    Thirty patients suffering from mass lesion in the parotid gland or cervical region were examined by computed tomography (CT). The photographed images were compared with the findings and pathological diagnoses obtained by surgical procedures. The conclusions were as follows: 1) Plain CT demonstrated the location of the parotid tumor. Contrast enhancement seemed to delineate the margin of the tumor more clearly. 2) By contrast enhancement, the branchiogenic cyst was differentiated from the parotid tumor, as a low density mass with an enhanced cyst wall. 3) Parotid tumors enhanced by contrast material did not always appear as solid tumors. 4) In some cases, CT numbers indicated the contents of the tumor. 5) The extension of the tumor to the parapharyngeal space was clearly depicted on CT. 6) It seemed to be difficult to evaluate the relationship of the parotid tumor to the facial nerve on plain CT.

    Full Text Available 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.

    Full Text Available A woman presented to the hospital due to postcoital vaginal bleeding. The patient was initially diagnosed with cervical carcinoma by clinicians at a local hospital. However, a biopsy of the cervical lesions revealed chronic inflammation and erosion of the cervical mucosa, and the rapid plasma reagin ratio titer was 1:256. The patient was eventually diagnosed with syphilitic cervicitis and treated with minocycline 0.1 g twice a day. The patient was cured with this treatment.

  5. Computerized axial tomography in traumatic cervical lesions

    Koyama, Tsunemaro

    1982-01-01

    Although plain computerized axial tomography cannot routinely demonstrate the spinal cord, it does provide excellent visualization of the bony outline of the spinal canal and vertebral column. So it should be reasonable to use this technique in cases of cervical traumatic disorders. In this paper we presented 10 cases of cervical traumatic lesions; 3 atlanto-axial dislocation, 2 cervical canal stenosis, 3 OPLL, 1 intramedullary hematoma and 1 C 2 -neurinoma. In some patients neurologic deficits were induced by cervical trauma. Bony lesions appeared more adequately deliniated than intraspinal lesions, however, in some cases intramedullary changes could also be demonstrated. The use of metrizamide with high resolution CT-scanner could improve the usefullness of this technique. (author)

    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. 

  8. Imaging in cardiac mass lesions

    Mundinger, A.; Gruber, H.P.; Dinkel, E.; Geibel, A.; Beck, A.; Wimmer, B.; Schlosser, V.

    1992-01-01

    In 26 patients with cardiac mass lesions confirmed by surgery, diagnostic imaging was performed preoperatively by means of two-dimensional echocardiography (26 patients), angiography (12 patients), correlative computed tomography (CT, 8 patients), and magnetic resonance imaging (MRI, 3 patients). Two-dimensional echocardiography correctly identified the cardiac masses in all patients. Angiography missed two of 12 cardiac masses; CT missed one of eight. MRI identified three of three cardiac masses. Although the sensitivity of two-dimensional echocardiography was high (100%), all methods lacked specificity. None of the methods allowed differentiation between myxoma (n=13) and thrombus (n=7). Malignancy of the lesions was successfully predicted by noninvasive imaging methods in all six patients. However, CT and MRI provided additional information concerning cardiac mural infiltration, pericardial involvement, and extracardiac tumor extension, and should be integrated within a preoperative imaging strategy. Thus two-dimensional echocardiography is the method of choice for primary assessment of patients with suspected cardiac masses. Further preoperative imaging by CT or MRI can be limited to patients with malignancies suspected on the grounds of pericardial effusion or other clinical results. (author)

    2009-07-01

    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

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

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

  14. New technologies in diagnosis of preinvasive cervical lesions

    Full Text Available Results of efficiency assessment of different diagnosis for preinvasive cervical lesions are represented in the article. During investigation the retrospective analysis of 353 patient histories of women with cervical intraepithelial neoplasia (primary and recurrent, who have been observed in Ivanovskiy regional oncological dispensary from 2002 to 2011, was performed. The accuracy rates of diagnosis of cervical intraepithelial neoplasia for one or several methods including cytological study, colposcopy and fluorescence cystoscopy were compared. Fluorescence diagnosis was performed with drug fotoditazin (LLC «VETA-GRAND», marketing authorisation №LS 001246 at dose of 1,0 mg/kg body weight. The final diagnosis was determined by results of histological study. The accuracy of cytological study accounted for 67,5–80,7%. Using colposcopy the exact diagnosis was determined in 67,9–74,4% of cases. Combination of cytological study with colposcopy improved the accuracy of diagnosis up to 82.1–88.9%. The superior results were for concurrent use of cytological study with colposcopy and fluorescence diagnosis – in such case the diagnosis was correct in 92,0–96,7% of patients. The analysis of results showed that using all methods of diagnosis the accuracy of diagnosis for recurrent cervical intraepithelial neoplasia was lower than for primary lesions. The decrease of diagnosis accuracy is probably related to previous diagnosis and therapeutic manipulations on cervix. Thus, multimodal diagnosis investigation with methods of fluorescence spectroscopy allows to improve accuracy of diagnosis for preinvasive cervical lesions

    We describe the technique and the results of the percutaneous aspiration biopsy (PAB) in a series of 9 patients presenting with neck pain and different degrees of myelopathy, in whom the cervical spine X-ray demonstrated lytic lesions of unknown origin. PAB is a useful, relatively safe technique, and leads to histological diagnosis between metastatic and inflammatory processes. Furthermore, in inflammatory lesions with negative hemoculture, PAB may help in detecting the micro-organism responsible and therefore allow a better antibiotic treatment. (orig.)

  16. [Analysis of etiological factors involved in noncarious cervical lesions].

    Tomasik, Małgorzata

    2006-01-01

    The etiopathology of noncarious cervical lesions (NCCL) is multifactorial and still not fully understood. Tooth wear is defined as loss of dental hard tissue by a chemical or mechanical process that does not involve bacteria. This form of tooth surface loss includes attrition, abrasion, erosion, and abfraction. Noncarious cervical lesions represent loss of tooth structure at the cementoenamel junction. The purpose of this clinical study of NCCL was to analyze the etiology in relation to age and to identify the most important risk factors associated with cervical lesions, as well as patients and teeth more susceptible to NCCL with a focus on more effective treatment of this condition. The study group comprised 124 patients with NCCL, aged 15-75 years (mean = 44). A questionnaire was distributed addressing medical history--gastric disorders, dietary habits--consumption of acidic drinks, dental history, oral hygiene practices, and parafunctional habits. Clinical examination of tooth wear was performed on four tooth surfaces after air-drying. The distribution and severity of tooth wear was graded using the tooth wear index (TWI) calculated with a computer programme allowing for tooth characteristic to be determined for each decade of life. Depth of the cervical defect was measured with a periodontal probe. TWI was devised to reveal the extent of tooth surface wear irrespective of the cause. Raw scores were compared with the computer using predetermined threshold values which are set to distinguish between acceptable and unacceptable pathological levels of tooth wear for each decade of life and each tooth surface. Dentition status, oral hygiene, periodontal status, gingival recession, number of teeth and their mobility, oral symptoms of parafunction and relationship to lateral and protrusive tooth contact schemes was assessed and analyzed. Statistical analyses were performed with the Stata Statistical Software: release 5. The risk of NCCL formation was estimated with

    Abnormal expression of Rho-GTPases has been reported in several human cancers. However, the expression of these proteins in cervical cancer has been poorly investigated. In this study we analyzed the expression of the GTPases Rac1, RhoA, Cdc42, and the Rho-GEFs, Tiam1 and beta-Pix, in cervical pre-malignant lesions and cervical cancer cell lines. Protein expression was analyzed by immunochemistry on 102 cervical paraffin-embedded biopsies: 20 without Squamous Intraepithelial Lesions (SIL), 51 Low- grade SIL, and 31 High-grade SIL; and in cervical cancer cell lines C33A and SiHa, and non-tumorigenic HaCat cells. Nuclear localization of Rac1 in HaCat, C33A and SiHa cells was assessed by cellular fractionation and Western blotting, in the presence or not of a chemical Rac1 inhibitor (NSC23766). Immunoreacivity for Rac1, RhoA, Tiam1 and beta-Pix was stronger in L-SIL and H-SIL, compared to samples without SIL, and it was significantly associated with the histological diagnosis. Nuclear expression of Rac1 was observed in 52.9% L-SIL and 48.4% H-SIL, but not in samples without SIL. Rac1 was found in the nucleus of C33A and SiHa cells but not in HaCat cells. Chemical inhibition of Rac1 resulted in reduced cell proliferation in HaCat, C33A and SiHa cells. Rac1 is expressed in the nucleus of epithelial cells in SILs and cervical cancer cell lines, and chemical inhibition of Rac1 reduces cellular proliferation. Further studies are needed to better understand the role of Rho-GTPases in cervical cancer progression

  5. Prevalence of high-grade squamous intraepithelial lesions and cervical cancer among patients with unsatisfactory colposcopic examination, without visible lesion

    Fernanda Rangel da Veiga

    Full Text Available CONTEXT AND OBJECTIVE: Cervical cancer is a serious public health problem in Brazil. For patients with unsatisfactory colposcopic examinations without visible lesions, but with cervical cytological tests suggesting high-grade squamous intraepithelial lesion (HSIL, the national recommendation is to repeat cervical cytological tests after three months. Our aim was to assess the prevalence of HSIL and cancer among patients with initial cervical cytological tests suggestive of HSIL but with unsatisfactory colposcopic examinations without visible lesions, in order to contribute towards the discussion regarding a more effective clinical approach that might diminish the likelihood of patient abandonment of follow-up before appropriate diagnosis and treatment. DESIGN AND SETTING: Cross-sectional study in Colposcopy Clinic of IFF/Fiocruz. METHOD: Patients admitted between December 1989 and April 2007 with cytological diagnoses of HSIL but with unsatisfactory colposcopic examinations without visible lesions underwent cervical cone biopsy. RESULTS: Sixty-five such patients were included, comprising 33.8% with HSIL and 4.6% with cancer, confirmed histologically. The other patients presented low-grade squamous intraepithelial lesion (26.1%, glandular dysplasia (1.5% and absence of disease (33.8%. CONCLUSION: The observed prevalence of cancer and HSIL does not seem to be enough to justify immediate referral for cone biopsies to investigate the cervical canal in these cases. The findings suggest that the recommendation of repeated cytological tests following an initial one with HSIL, among patients with unsatisfactory colposcopic examinations without visible lesions, is appropriate in our setting. Efforts are needed to ensure adherence to follow-up protocols in order to reduce the chances of losses.

  6. The value of thyroglobulin in washout of fine needle aspirate from 16 cervical lesions in patients with thyroid cancer.

    2013-11-01

    Thyroglobulin in the needle washout (Tg-FNA) and cytology of fine needle aspiration (cyto-FNA) are recommended for diagnosis of metastatic lymphadenopathies and recurrence of differentiated thyroid cancer. The objective of this study was to assess the value of these procedures in 16 cervical masses from patients with thyroid cancer of the follicular epithelium (TC). The study included six patients with TC and cervical lymphadenopathies evaluated before initial thyroid surgery and 10 patients followed up after TC surgery with cervical lumps discovered. FNA was performed in all 16 masses. Results of cyto-FNA, Tg-FNA and of the combined tests were compared to the final diagnosis of each lesion. Among 10 lesions proven to be malignant at surgery, cyto-FNA, Tg-FNA and the combination of both allowed for adequate diagnosis in 7, 9, and 10 cases respectively. Among 6 lesions considered to be benign, cyto-FNA was able to confirm diagnosis in 4, was non-diagnostic in one, and was falsely negative in the remaining case, while Tg-FNA was below the established cut-off value (to consider malignancy) in all cases. In patients with TC and suspect cervical masses, Tg-FNA improved the diagnostic yield of cyto-FNA alone, thus warranting its routine recommendation when FNA is performed. However, universal standardization of the technique and definition of valid cut-off thyroglobulin values (depending on the immunoassay used) above which the lesion should be considered to be malignant are still pending.

Cervical cell specimens from patients with histopathologically confirmed cervical lesions at 7 hospitals in Beijing were examined with a validated HPV kit for 13 hr-HPV genotypes during the study period. The patients were divided into a low-grade cervical lesions group (cervical intraepithelial neoplasia grade 1, CIN1) and a high-grade cervical lesions group (CIN2+, including cervical intraepithelial neoplasia grade 2, CIN2; cervical intraepithelial neoplasia grade 3, CIN3; squamous cervical cancer, SCC; and adenocarcinoma of the cervix, ACC) based on the histopathology results. A total of 2817 eligible patients were enrolled, including 610 cases identified as CIN1 and 2207 as CIN2+. The hr-HPV positive rates in the CIN1 and CIN2+ groups were 78.2% (477/610) and 93.3% (2060/2207), respectively. The most frequently detected genotypes were HPV16, 58, 52 and18 in the CIN1 group and HPV16, 58, 33, and 52 in the CIN2+ group, in descending order of prevalence. In addition, the prevalence of HPV18 among the patients with ACC was 28.6% (14/49), significantly >7.2% (54/752) prevalence among the SCC patients (P HPV infections gradually deceased to 44.2% in the CIN2 patients, 36.7% in the CIN3 patients, and 35.3% in the cervical cancer (CC) patients, which included SCC and ACC patients. In cases of multiple hr-HPV infections in the CIN2+ group, double infections accounted for ∼76.6%, and HPV16+58, HPV16+52, and HPV16+18 were the most common combinations, in descending order. The most frequent combination for triple infections was HPV16+58+31, with a rate of 4.2%. The highest positive rate occurred in the ≤24 year-old group for all types of cervical lesions. The prevalence of HPV genotypes in the targeted population with high-grade cervical lesions differs from that of other countries. This

    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.

    Full Text Available Aim: Our aim is to detect the incidence and rate of high risk HPV-DNA in patients with cervical cancer,HGSIL,LGSIL or ASCUS and compare those findings with patients presenting with totally benign servical smears as well as to search for the factors influencing these rates. Materials and Methods: 85 patients with cytologic and histologic proven cervical carcinoma, HGSIL, LGSIL, ASCUS and 178 patients with totally benign (normal or infecton smear results as a control group who attented to Atatürk Training and Research Hospital 3rd Obstetrics and Gynecology Clinics between the dates of January 2006- July 2008 were included to our study. Within these patients age, first sexual intercourse, age, smoking habit, number of sexual partners, age of menarche and contraception methods were recorded. Pap smears and smears for detection of high risk HPV were taken concurrently from cervical transformation zone and external cervical ostium and the incidence of high risk HPV-DNA were examined. Results: High risk HPV DNA rate was detected as 65.2% positive in cervical carcinoma patients in our study. High risk HPV-DNA was positive in 54.8% of patients with HGSIL while it was positive in 25% of patients with LGSIL. High risk HPV-DNA was positive in 5% of patients with benign cervical cytology results. Discussion: The positivity rates of high risk HPV-DNA results in cervical carcinoma, HGSIL, LGSIL patients and in patients with benign cervical cytologies were statistically significant. When the age of menarche and contraception method were considered the HPV-DNA positivity rates’ differences were statistically insignificant.The differences for the age of first sexual intercourse, number of sexual partners, age and smoking habits were statistically significant.

    Objective To evaluate the diagnostic accuracy of the 2011 International Federation for Cervical Pathology and Colposcopy (IFCPC) colposcopic terminology. Methods The clinicopathological data of 2262 patients who underwent colposcopy from September 2012 to September 2016 were reviewed. The colposcopic findings, colposcopic impression, and cervical histopathology of the patients were analyzed. Correlations between variables were evaluated using cervical histopathology as the gold standard. Results Colposcopic diagnosis matched biopsy histopathology in 1482 patients (65.5%), and the weighted kappa strength of agreement was 0.480 (Pterminology can improve the diagnostic accuracy for all lesion severities. The categorization of major changes and minor changes is appropriate. However, colposcopic diagnosis remains unsatisfactory. Poor reproducibility of type 2 transformation zone and the significance of leukoplakia require further study. PMID:29507681

    Background Data from Egyptian studies provide widely varying estimates on the prevalence of pre-malignant and malignant cervical abnormalities and human papilloma virus (HPVs) infection. To define the prevalence and risk factors of pre-invasive and invasive cervical cancer (cacx), a community based full-scale cross sectional, household survey including 5453 women aged between 35 and 60 years was conducted. Methods The study period was between February 2000 and December 2002. Initially, conventional Papanicolaou (Pap) smears were evaluated using the Bethesda system (TBS), followed by colposcopic guided biopsy (CGB) for all epithelial abnormalities (EA). In a third step, HPV was tested on all EA by in-situ hybridization (ISH) using first the broad spectrum HPV probe recognizing HPVs 6, 11, 16, 18, 30, 31, 35, 45, 51 and 52 followed by subtyping with probes 6/11, 16/18 and 31/33. Lastly, unequivocal cases were immunostained for herpes simplex type-2 (HSV-2), cytomegalovirus (CMV), and human immunodeficiency virus (HIV). Results EA representing 7.8% (424/5453), were categorized into atypical squamous cell of undetermined significance (ASCUS) (34.4%), atypical glandular cell of undetermined significance (AGCUS) (15.3%), combined ASCUS and AGCUS (3.1%), low grade squamous intraepithelial lesions (SIL) (41.0%), high grade SIL (5.2%) and invasive lesions (1%). CGB of EA (n = 281) showed non neoplastic lesions (12.8%), atypical squamous metaplasia (ASM) (19.2%), cervical intraepithelial neoplasia I (CIN) (44.4%), CIN II (4.4%), CINIII (2.8%), endocervical lesions (5.2%), combined squamous and endocervical lesions (10.0%), invasive squamous cell carcinoma (SCC) (0.02%) and extranodal marginal zone B cell lymphoma (MZBCL) (0.02%). The overall predictive value of cytology was 87% while the predictive value for high grade lesions was 80%. On histological basis, HPVs were present in 94.3% of squamous lesions while it was difficult to be identified in endocervical ones. ISH

    Cervical cancer prevalence in Rwanda has not been well-described. Visual inspection with acetic acid or Lugol solution has been shown to be effective for cervical cancer screening in low resource settings. The aim of the study is to understand the prevalence and risk factors for cervical cancer and pre- cancerous lesions among Rwandan women between 30 and 50 old undergoing screening. This cross-sectional analytical study was done in 3 districts of Rwanda from October 2010 to June 2013. Women aged 30 to 50 years screened for cervical cancer by trained doctors, nurses and midwives. Prevalence of pre-cancerous and cancerous cervical lesions was determined. Bivariate and multivariate logistic regressions were used to assess risk factors associated with cervical cancer. The prevalence of pre-cancer and invasive cervical cancer was 5.9% (95% CI 4.5, 7.5) and 1.7% (95% CI 0.9, 2.5), respectively. Risk factors associated with cervical cancer in multivariate analysis included initiation of sexual activity at less than 20 years (OR=1.75; 95% CI=(1.01, 3.03); being unmarried (single, divorced and widowed) (OR=3.29; 95% CI=( 1.26, 8.60)); Older age of participants (OR= 0.52; 95% CI= (0.28, 0.97)), older age at the first pregnancy (OR=2.10; 95% CI=(1.20, 3.67) and higher number of children born (OR=0.42; 95%CI =(0.23, 0.76)) were protective. Cervical cancer continues to be a public health problem in Rwanda, but screening using VIA is practical and feasible even in rural settings.

  19. Prevalence of Specific Types of Human Papiloma Virus in Cervical Intraepithelial Lesions and Cervical Cancer in Macedonian Women

    Aleksioska-Papestiev, Irena; Chibisheva, Vesna; Micevska, Megi; Dimitrov, Goran

    2018-01-01

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

    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.

    Cervical cancer is the third most common gynecological malignancy in Saudi women with an estimated incidence rate of 1.9 cases per 100 000 women-years. More than 40% of cervical cancer cases are diagnosed at advanced stages due to lack of a routine screening program in Saudi Arabia. Thus, national guidelines for routine screening and treatment of precancerous cervical lesions are needed. The Saudi Centre for Evidence-Based Healthcare invited a panel of local experts and partnered them with a team from McMaster University in Canada for methodological support, to develop national clinical practice guidelines on the screening and treatment of precancerous lesions for cervical cancer. After the panel identified key clinical questions, the McMaster University working group updated existing systematic reviews that had been used for the 2013 WHO Guidelines for screening and treatment of precancerous lesions for cervical cancer prevention. Recommendations were based on the GRADE (Grading of Recommendations, Assessment, Development and Evaluation) approach. Those recommendations took into account the available evidence, patient values and preferences, and resource use in the Saudi context. The panel provided recommendations on two major issues: screening for precancerous lesions (cervical intraepithelial neoplasia 2 & 3) and treatment of those lesions to prevent cervical cancer in women who tested positive after screening. The Saudi expert panel recommends using the HPV DNA test followed by colposcopy or cytology (Pap test) followed by colposcopy to screen for CIN2+ in women at risk of cervical cancer. The panel recommends cryotherapy or loop excision electrosurgery procedure (LEEP) over cold knife cone biopsy to treat women at risk of cervical cancer that tests positive for CIN2+. Universal screening for precancerous cervical dysplasia in women in Saudi Arabia is recommended using HPV testing and or cytology. Either cryotherapy or LEEP are preferred for treatment. National

    Ko, Eun Sook; Choi, Hye Young; Kim, Rock Bum; Noh, Woo-Chul

    2012-01-01

    Objectives: The purpose of this study was to determine the performance of the conventional ultrasonography (US) and sonoelastography (SE) in three conditions of all lesions, confined to mass, and confined to non-mass lesion and to compare the performance of each modality between mass and non-mass lesion. Materials and methods: A total 364 patients with 375 lesions were evaluated with US and subsequently SE before performing US-guided biopsy. Two radiologists retrospectively analyzed conventional US and elasticity images by consensus. The US findings were classified as mass or non-mass lesion. With final pathology as reference, in each case of all lesions, masses, and non-mass lesions, areas under the ROC curves (Az) were calculated and compared for the two techniques. The comparison of Az values between the curves for US and SE, and between the curves for mass and non-mass lesion was performed. Results: Among 375 lesions, 104 (28%) lesions were malignant and 271 (72%) lesions were benign. 36 (9.6%) of 375 lesions were classified as non-mass lesion at US. There were statistically significant difference of performance between US and SE in cases of all lesion (p = 0.003) and mass (p = 0.023). However, there was no statistically significant difference of performance in case of non-mass lesion (p = 0.5). Comparisons of the Az values of US and SE between mass and non-mass lesions were not statistically significant (p = 0.745, p = 0.415, respectively). Conclusion: There was no statistically significant difference of performance of US and SE between mass and non-mass lesion.

  5. Comparison of MRI pulse sequences for investigation of lesions of the cervical spinal cord

    2000-01-01

    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.)

    2017-02-01

    Full Text Available Abstract Background Cervical Cancer (CC is the number one cancer among women in sub-Saharan Africa. Although CC is preventable, most women in developing countries do not have access to screening. Methods This cross-sectional study was conducted to determine the prevalence and risk factors for cervical lesions using visual inspection with acetic acid (VIA among 112 HIV positive and 161 negative women aged 18–69 years. Results The presence of cervical lesions was greater among HIV positive (22.9% than HIV negative women (5.7%; p < 0.0001. In logistic models, the risk of cervical lesions among HIV positive women was 5.24 times higher when adjusted by age (OR 5.24, CI 2.31–11.88, and 4.06 times higher in a full model (OR 4.06, CI 1.61–10.25, than among HIV negative women. In the age-adjusted model women who had ≥2 lifetime sexual partners were 3 times more likely (OR 3.00, CI 1.02–8.85 to have cervical lesions compared to women with one lifetime partner and the odds of cervical lesions among women with a history of STIs were 2.16 greater (OR 2.16, CI 1.04–4.50 than among women with no previous STI. In the fully adjusted model women who had a previous cervical exam were 2.5 times more likely (OR 2.53, CI 1.06–6.05 to have cervical lesions than women who had not. Conclusions The high prevalence of HIV infection and the strong association between HIV and cervical lesions highlight the need for substantial scale-up of cervical screening to decrease the rate of CC in Swaziland.

  7. Human papillomavirus infection and cervical lesions in rheumatic diseases: a systematic review.

    Ana Raposo

    2016-07-01

    Full Text Available An association between immune-mediated diseases and cervical pre-malignant and malignant lesions is described, having the human papillomavirus (HPV infection a causal role. Related studies have been generally focused on systemic lupus erythematosus (SLE patients, but relatively to other diseases, such as rheumatoid arthritis (RA, Sjögren's syndrome (SS and systemic sclerosis (SSc, data has not been systematically evaluated. We conducted a systematic review analysis of the literature in PubMed, including articles published until March of 2015, in patients with RA, SS, SLE and SSc, to evaluate the frequency of HPV infection, cervical dysplasia and cervical cancer, and associated factors, with particular interest on the role of glucocorticoids and immunosuppressive treatment. Moreover, safety and efficacy of HPV vaccines in these patients was investigated. Of 476 articles identified, 27 were finally included. The studies showed an increased prevalence of cervical dysplasia and cancer, with the HPV infection being an important associated factor, in particular in SLE patients. The data relatively to other rheumatic diseases was very scarse, but an increased prevalence of smear abnormalities was also found in RA. Patients exposed to glucocorticoids and to long-term immunosuppression, particularly cyclophosphamide, have increased risk of presenting more pre-malignant lesions than the general population. The available vaccines seem to be generally safe and immunogenic in the short- period evaluation, but long-term follow-up is required to evaluate the impact of the vaccine in the protection against HPV infection and occurrence of high-grade cervical lesions.

  9. Prevalence of intraepithelial lesion in cervical screening cytology in a First-level Care Unit

    Solís, José Gabriel; Briones-Torres, Tomás Iván

    2018-01-01

    Cervical cancer represents the second leading cause of malignant neoplasm mortality in women globally. Cervical cytology is the most important screening study. It is therefore of interest to know the prevalence of cytological alterations in the Mexican population. In this study the objective was to calculate the prevalence of intraepithelial lesion in cervical screening cytology. An observational, descriptive and cross-sectional study was developed; the sample was 379 patients from 21 to 64 years of age; we included patients who underwent cervical screening cytology registered in the Detección Oportuna de Cáncer Cervicouterino (DOC-CACU) program database. A descriptive analysis of the data was performed. A prevalence of intraepithelial lesion of 4.49% was found. The 3.17% corresponded to LIEBG and 1.32% to LIEAG. No reports of invasive carcinoma were found. Of these patients, 64.71% corresponded to the age group from 41 to 60 years. 52.94% had had their last cytology in the previous 3 years or more and 35.29% were in postmenopause. A prevalence consistent with what was described in the literature was found. More than half of the affected patients had their last cytology in the previous 3 or more years and corresponded to the age group from 41 to 60 years. A high proportion of patients were in postmenopause.

    Full Text Available Eighty-nine patients with lower cervical spine fractures or dislocations were evaluated for risk factors of neurological lesion. The age, sex, level and pattern of fracture and sagittal diameter of the spinal canal were analysed. There were no significant differences on the age, gender, level and Torg's ratio between intact patients and those with nerve root injury, incomplete or complete spinal cord injuries. Bilateral facet dislocations and burst fractures are a significant risk factor of spinal cord injury.

    We describe the technique and the results of the percutaneous aspiration biopsy (PAB) in a series of 9 patients presenting with neck pain and different degrees of myelopathy, in whom the cervical spine X-ray demonstrated lytic lesions of unknown origin. PAB is a useful, relatively safe technique, and leads to histological diagnosis between metastatic and inflammatory processes. Furthermore, in inflammatory lesions with negative hemoculture, PAB may help in detecting the micro-organism responsible and therefore allow a better antibiotic treatment. (orig.).

    To characterize histopathological status, high-risk human papillomavirus (hr-HPV) infection status, and associated risk factors in patients with atypical squamous cells of undetermined significance (ASCUS). Cervical biopsies obtained from 130 ASCUS patients were subjected to histopathological examination and hr-HPV testing. Associations between advanced lesions and hr-HPV load or age were analyzed, and the confounding factors for high-grade cervical lesions were identified. Cervical biopsies from ASCUS patients had a wide range of pathological states, ranging from normal to invasive cervical carcinoma. High-risk HPV infection was significantly associated with advanced cervical lesions in ASCUS patients; hr-HPV infection and the number of gestations were risk factors for developing advanced cervical disease. A significant portion of ASCUS patients harbor advanced cervical lesions. The number of gestations and hr-HPV infection can increase the risk of developing advanced cervical lesions in ASCUS patients.

    2018-01-01

    Background The association of trigeminal neuralgia with pontine lesions has been well documented in multiple sclerosis, and we tested the hypothesis that occipital neuralgia in multiple sclerosis is associated with high cervical spinal cord lesions. Methods We retrospectively reviewed the records of 29 patients diagnosed with both occipital neuralgia and demyelinating disease by a neurologist from January 2001 to December 2014. We collected data on demographics, clinical findings, presence of C2-3 demyelinating lesions, and treatment responses. Results The patients with both occipital neuralgia and multiple sclerosis were typically female (76%) and had a later onset (age > 40) of occipital neuralgia (72%). Eighteen patients (64%) had the presence of C2-3 lesions and the majority had unilateral symptoms (83%) or episodic pain (78%). All patients with documented sensory loss (3/3) had C2-3 lesions. Most patients with progressive multiple sclerosis (6/8) had C2-3 lesions. Of the eight patients with C2-3 lesions and imaging at onset of occipital neuralgia, five (62.5%) had evidence of active demyelination. None of the patients with progressive multiple sclerosis (3/3) responded to occipital nerve blocks or high dose intravenous steroids, whereas all of the other phenotypes with long term follow-up (eight patients) had good responses. Conclusions A cervical spine MRI should be considered in all patients presenting with occipital neuralgia. In patients with multiple sclerosis, clinical features in occipital neuralgia that were predictive of the presence of a C2-3 lesion were unilateral episodic symptoms, sensory loss, later onset of occipital neuralgia, and progressive multiple sclerosis phenotype. Clinical phenotype predicted response to treatment.

    Vinceti, Giulia; Zini, Andrea; Nichelli, Paolo; Mandrioli, Jessica

    2012-01-01

    We describe the case of a 39-year-old woman with signs and symptoms suggesting cauda equina syndrome. Lumbosacral magnetic resonance imaging (MRI) demonstrated no lesion at this level, while cervical MRI showed a T2-hyperintense lesion in the middle-right anterolateral region of the cervical spinal cord, which may explain the symptoms by involving the anterior spinothalamic tract. We suggest that in cases with cauda equina syndrome presentation and normal lumbosacral MRI, a cervicodorsal lesi...

    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

  16. [The diagnostic value of ultrasonic elastography and ultrasonography comprehensive score in cervical lesions].

    Lu, R; Xiao, Y

    2017-07-18

    Objective: To evaluate the clinical value of ultrasonic elastography and ultrasonography comprehensive scoring method in the diagnosis of cervical lesions. Methods: A total of 116 patients were selected from the Department of Gynecology of the first hospital affiliated with Central South University from March 2014 to September 2015.All of the lesions were preoperatively examined by Doppler Ultrasound and elastography.The elasticity score was determined by a 5-point scoring method. Calculation of the strain ratio was based on a comparison of the average strain measured in the lesion with the adjacent tissue of the same depth, size, and shape.All these ultrasonic parameters were quantified, added, and arrived at ultrasonography comprehensive scores.To use surgical pathology as the gold standard, the sensitivity, specificity, accuracy of Doppler Ultrasound, elasticity score and strain ratio methods and ultrasonography comprehensive scoring method were comparatively analyzed. Results: (1) The sensitivity, specificity, and accuracy of Doppler Ultrasound in diagnosing cervical lesions were 82.89% (63/76), 85.0% (34/40), and 83.62% (97/116), respectively.(2) The sensitivity, specificity, and accuracy of the elasticity score method were 77.63% (59/76), 82.5% (33/40), and 79.31% (92/116), respectively; the sensitivity, specificity, and accuracy of the strain ratio measure method were 84.21% (64/76), 87.5% (35/40), and 85.34% (99/116), respectively.(3) The sensitivity, specificity, and accuracy of ultrasonography comprehensive scoring method were 90.79% (69/76), 92.5% (37/40), and 91.38% (106/116), respectively. Conclusion: (1) It was obvious that ultrasonic elastography had certain diagnostic value in cervical lesions. Strain ratio measurement can be more objective than elasticity score method.(2) The combined application of ultrasonography comprehensive scoring method, ultrasonic elastography and conventional sonography was more accurate than single parameter.

    Full Text Available Abstract Background The HVP vaccine is a useful tool for preventing cervical cancer. 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: Introduction: Characterization of neck lesions is usually not possible without histopathological examination. Objective: To evaluate whether adhesion diffusion coefficient (ADC) values calculated from diffusion weighted magnetic resonance imaging can be used to characterize neck lesions. Material and methods: Diffusion-weighted echo planar MR imaging with b factors of 0, 500 and 1000 sec/mm 2 was prospectively performed with a 1.5 T MR unit in 119 neck lesions in 119 patients. ADC values were measured by 2 radiologists independently on an independent workstation console. Intraclass correlation coefficients were calculated. The mean ADC values were compared using Mann-whitney u test. Results: There was a statistically significant difference between the mean ADC values of benign and malign solid lesions (1.13±0.62 x 10 -3 mm 2 /s and 0.82±0.21 x 10 -3 mm 2 /s respectively). There was no malign lesion with an ADC value more than 1.15 x 10 -3 mm 2 /s. The mean ADC value of malignant lymphomas (0.61±0.14 x 10 -3 ) was significantly smaller than the mean ADC values of other cervical lymphadenopathies. But there was no statistically significant difference between the mean ADC values of reactive, granulomatous and metastatic lymph nodes. Conclusion: ADC values cannot totally distinguish the histopathological subgroups of the neck lesions but shows significant differences between malign and benign lesions.

    To determine the potential clinical utility of tumor markers CEA, TPA, and SCC-Ag for early detection of cervical precancerous lesions. A case-control study was carried out on 120 women (46 patients with histologically confirmed cervical precancerous lesions and 74 healthy controls). The significance of serum selected tumor markers in early detection of cervical intraepithelial neoplasia (CIN) were assessed. Of the case group, the rates of CIN I, II, III, was 69.6%, 23.9%, and 6.5%, respectively. According to the manufacturer's cut-off values of 2 ng/ml, 5 ng/ml, and 70 U/ml for SCC-Ag, CEA and TPA tests, in that order, SCC-Ag test had a sensitivity of 13%, but CEA and TPA tests could not distinguish between case and control groups. The diagnostic sensitivities were highest at cut-off values of 0.55 ng/ml for SCC-Ag, 2.6 ng/ ml for CEA, and 25.5 U/ml for TPA which were 93%, 61%, and 50%, respectively. However, the area under the receiver operating characteristic curve was the largest for SCC-Ag (0.95 vs. 0.61 and 0.60 for CEA and TPA, respectively). Moreover, there was a highly significant direct correlation between SCC-Ag concentration and the degree of cervical precancerous lesions (r=0.847, ptumor marker in Iranian patients with CIN and it needs to be more evaluated by studies with larger populationa.

    Subjective classification of masses on mammograms is a difficult task. On average, about 25% of masses referred for surgical biopsy are actually malignant. The authors are developing, as an aid to radiologists, a computerized scheme for the classification of lesions in mammograms to reduce the false-negative and false-positive diagnoses of malignancies. The classification scheme involves the extraction of border information from the mammographic lesion in order to quantify the degree of spiculation, which is related to the possibility of malignancy. Clinical film mammograms are digitized with an optical drum scanner (0.1-mm pixel size) for analysis on a Micro VAX 3500 computer. Border information (fluctuations) is obtained from the difference between the lesion border and its smoothed border. Using the rms variation of the frequency content of these fluctuations, approximately 85% of the cancerous lesions were correctly classified as malignant, while 15% of benign lesions were misclassified, in a preliminary study

  2. Methylated Host Cell Gene Promoters and Human Papillomavirus Type 16 and 18 Predicting Cervical Lesions and Cancer.

    Nina Milutin Gašperov

    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.

    Five cystic mass lesions of the pancreas were exemined by MRI. Multiplocular fluid components were demonstrated as areas of various signal intensity in mucinous cystadenoma and cystadenocarcinoma. Gas within the cystic mass was noted in ductectatic mucinous cystadenocarcinoma. Honeycomb pattern and classification were not depicted in serous cystadenoma. Necrotic matter was demonstrated as area of lower signal than liver in pseudocyst. These results were then compared with CT and ultrasound and at present enhanced CT combined with ultrasound is more diagnostic than MRI for cystic mass lesions of the pancreas. (author)

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

    Cervical cancer is the leading cause of cancer deaths among females in Angola and human papillomavirus (HPV) is the main risk factor for the development of pre-cancerous squamous intraepithelial lesions. The diversity and frequency of HPV types in Angola has yet to be reported. To determine the frequency of HPV among women with squamous intraepithelial lesions from women in Luanda, Angola. Study participants included women diagnosed with cytological abnormalities that voluntarily provided Pap smears (n = 64). Genomic DNA was extracted from the samples for use as templates in the PCR amplification of HPV sequences. PCR products were sequenced to determine HPV type. HPV DNA was detected in 71.9% (46/64) in the samples. A higher diversity of HPV types was found in the cytological lesions, such as ASCUS and LSIL (HPV16, 6, 18, 31, 58, 66, 70 and 82, in order of frequency) than that detected for HSIL and SSC (HPV16, 18, 6 and 33). The most prevalent HPV type were: HPV16, HPV6 and HPV18. This is the first report on HPV type diversity and frequency in woman of Angola. The results suggest that large-scale studies across Africa would improve our understanding of interrelationship between HPV infections and cervical cancer. More directly, the identification of the HPV types most prevalent suggests that women in Angola would benefit from currently available HPV vaccines.

    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.

    The aim of the present study was confront the results of the cytological examination with hybrid capture II in the diagnosis of induced cervical intraepithelial lesion-HPV, correlating the cytological findings with biomoleculares. The research was carried through in a group of 160 sexually active women who had espontaneamente looked its gynecologists for consultation of routine, having been submitted to the collection of cervicovaginal material for cytology and for examination of hybrid capture II in the Centro de Patologia Clínica and the Hospital e Maternidade Promater, in the city of the Natal-RN. The results had shown to relatively high numbers of positive cases for HPV using hybrid capture II (41.87%) and the cytology (23.75%). The agreement between the two studied methods relatively was raised (59.38%). It was evident also that the viruses with high oncogênico potential had presented found in the compatible cytology with Lesion of low risk (11.88%), followed of Lesion of high risk (NIC II and III); already the viruses with low oncogênico potential were more associates the Lesion of low risk (6.25%), followed of Lesion of high risk. The cytology, exactly with its limitations, is an important method in the detention of attributable patologias to the HPV, emphasizing that the molecular method comes to complement it and to consolidate the cytological findings.

  8. Abfraction, abrasion, biocorrosion, and the enigma of noncarious cervical lesions: a 20-year perspective.

    Grippo, John O; Simring, Marvin; Coleman, Thomas A

    2012-02-01

    Hitherto, noncarious cervical lesions (NCCLs) of teeth have been generally ascribed to either toothbrush-dentifrice abrasion or acid "erosion." The last two decades have provided a plethora of new studies concerning such lesions. The most significant studies are reviewed and integrated into a practical approach to the understanding and designation of these lesions. A paradigm shift is suggested regarding use of the term "biocorrosion" to supplant "erosion" as it continues to be misused in the United States and many other countries of the world. Biocorrosion embraces the chemical, biochemical, and electrochemical degradation of tooth substance caused by endogenous and exogenous acids, proteolytic agents, as well as the piezoelectric effects only on dentin. Abfraction, representing the microstructural loss of tooth substance in areas of stress concentration, should not be used to designate all NCCLs because these lesions are commonly multifactorial in origin. Appropriate designation of a particular NCCL depends upon the interplay of the specific combination of three major mechanisms: stress, friction, and biocorrosion, unique to that individual case. Modifying factors, such as saliva, tongue action, and tooth form, composition, microstructure, mobility, and positional prominence are elucidated. By performing a comprehensive medical and dental history, using precise terms and concepts, and utilizing the Revised Schema of Pathodynamic Mechanisms, the dentist may successfully identify and treat the etiology of root surface lesions. Preventive measures may be instituted if the causative factors are detected and their modifying factors are considered. © 2011 Wiley Periodicals, Inc.

  9. Examining the prevalence and characteristics of abfractionlike cervical lesions in a population of U.S. veterans.

    2001-12-01

    Abfraction is believed to be caused by biomechanical loading forces. It may be due to flexure and ultimate fatigue of tooth tissues that occur away from the point of occlusal loading. Other possible causes of cervical lesions include toothbrush abrasion and erosion. The purpose of this study was to investigate the characteristics and prevalence of abfraction-like lesions in a population of U.S. veterans. The authors evaluated 103 teeth with noncarious cervical lesions in 32 subjects and characterized them based on the surface on which the lesion was located, history of toothbrush abrasion, size of the lesion, presence of plaque, surface texture, and presence and size of occlusal wear facets. Clinical examination revealed that adjacent control teeth had a significantly lower percentage of surfaces with plaque than did teeth with cervical lesions. Control teeth also had significantly less gingival recession than did affected teeth. Seventy-five percent of subjects reported a history of using a firm toothbrush, and 78.1 percent reported using a brushing technique that is known to cause toothbrush abrasion in the affected area. Affected teeth had neither significantly different occlusal wear facets nor occlusal contacts than control teeth. No significant correlations were found between cervical lesion dimensions and facet area. Toothbrush abrasion is strongly suspected as contributing to the formation of the majority of wedge-shaped lesions in this group of subjects. A small subset of lesions is thought to have resulted from some other phenomenon. Although the presence or contribution of occlusal stresses in the direct formation of these lesions could not be measured directly, the possibility of abfraction could not be eliminated. Because the existence of abfraction could not be ruled out in about 15 percent of the cases, teeth with noncarious, wedge-shaped lesions warrant careful occlusal evaluation, with the possible need for occlusal adjustment or bitesplint therapy

    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.

    1984-01-01

    Until recently, solitary coin lesion of pulmonary disease has been a conspicuous problem in radiologic diagnosis. It is now well informed that CT has offered high resolution with its objective CT numbers to provide additional information in terms of anatomic and pathologic changes. Here by the aid of CT, the authors has retrospectively patients with various shape of round masses thus illustrating the advantage of it over conventional X-ray in diagnosis. 1. Total 53 patients, including 34 males and 19 females, aging between 19 to 76 years old with nodule or mass of any size ranging 1 to 13 cm in diameter were observed. 2. On plain chest X-ray they were identified where 50 patients has single round nodular or mass, only one had two masses which were ecchinococcal cysts, and the rest two had invisible lesions, only detected by CT. 3. With philips tomoscan 310, CT scan was taken 12 mm thicken slice during quiet respiration. Using the ROI cursor the average CT number of the central area was calculated 1.0 cm in side the outer border of the mass. 4. As a consequence of their pathologic features, they were itemized to 4 group as 36 solid, 9 cystic, 4 consolidative and 4 cavitary lesions. 5. Correct diagnosis of 3 cystic lesions, 4 diffuse calcification, 1 A-V malformation were available by CT densitometry. 6. By the aid of better resolution and additional cross-sectional orientation of CT, 3 extrapulmonary lesions, 3 segmental consolidations, 2 bronchocele, and 2 solitary metastasis, were helpful in diagnosis. 7. Also helpful in determining the extent of intrathoracic extent of bronchogenic carcinoma for the same reason but given clues were not more than the ordinary. 8. However, the limitation of the CT densitometry led to miss diagnosis of 3 examples of cystic vs.solid lesions, and CT density of noncalcified granuloma together with bronchogenic carcinoma, did not have a clear cut separation in between.

    2010-09-01

    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

    Full Text Available Aim. To assess feasibility of integrating family planning counselling into mass screening for cervical cancer in Guinea. Methodology. This was a descriptive cross-sectional study conducted over a month in Guinea regional capital cities. The targeted population comprised women aged 15 to 49 years. Nearly 4000 women were expected for the screening campaigns that utilized VIA and VIL methods with confirmation of positive tests through biopsy. A local treatment was immediately performed when the patient was eligible. Results. Overall 5673 women aged 15 to 60 years were received, a surplus of 42% of the expected population. 92.3% of women were aged 15–49 years and 90.1% were 25–49 years. Long-acting methods were the most utilized (89.2% of family planning users. 154 precancerous and cancerous lesions were screened, a global positivity rate of 2.7%. Conclusion. Integration of counselling and family planning services provision during cervical cancer mass screening is a feasible strategy. A cost-effective analysis of this approach would help a better planning of future campaigns and its replication in other contexts.

  14. Space-occupying, inflammatory and dyplastic lesions of the cranio-cervical junction seen in nuclear magnetic resonance imaging (MRI)

    Friedburg, H.; Schumacher, M.; Hennig, J.

    1987-01-01

    Lesions of the cranio-cervical junction have acquired a special place amongst lesions of the posterior cranial fossa and the upper cervical region. This is due to the unusually long period between the appearance of the first symptoms and reaching a conclusive diagnosis. Frequently such lesions cannot be detected by either normal X-rays or conventional tomographic techniques. The introduction, however, of computer tomography (CT) and, in particular, magnetic resonance imaging (MRI) has made the examination of the critical zone of the cranio-cervical junction much easier and the diagnosis of thee lesions has now become largely dependent upon those techniques. Because soft tissue contrast is intrinsic to MRI this technique, in particular, has made possible substantial improvements in the quality of images of ligaments and soft tissue than those provided by standard CT. In this paper, the advantages which are provided by MRI in the context of the diagnosis of non-bony lesions in the cranio-cervical region are presented and discussed

  15. High-grade cervical lesions among women attending a reference clinic in Brazil: associated factors and comparison among screening methods.

    Neide T Boldrini

    Full Text Available Although screening for cervical cancer is recommended for women in most countries, the incidence of cervical cancer is greater in developing countries. Our goal was to determine the prevalence and factors associated with high-grade lesions/cervical cancer among women attending a reference clinic in Brazil and evaluate the correlation of histology with cytology, colposcopy and the high-risk HPV (HR-HPV tests.A cross-sectional study of women attending a colposcopy clinic was carried out. The patients were interviewed to collect demographic, epidemiological and clinical data. Specimens were collected for cervical cytology, Chlamydia trachomatis and HPV testing using the Hybrid Capture (HC and PCR tests. Colposcopy was performed for all patients and biopsy for histology when cell abnormalities or cervical intraepithelial neoplasia (CIN were present.A total of 291 women participated in the study. The median age was 38 years (DIQ: 30-48 years. The prevalence of histologically confirmed high-grade lesions/cervical cancer was 18.2% (95%, CI: 13.8%-22.6%, with 48 (16.5% cases of CIN-2/CIN-3 and 5 (1.7% cases of invasive carcinoma. In the final logistic regression model, for ages between 30 and 49 years old [OR = 4.4 (95%: 1.01-19.04, history of smoking [OR = 2.4 (95%, CI: 1.14-5.18], practice of anal intercourse [OR = 2.4 (95%, CI: 1.10-5.03] and having positive HC test for HR-HPV [OR = 11.23 (95%, CI: 4 0.79-26, 36] remained independently associated with high-grade lesions/cervical cancer. A total of 64.7% of the cases CIN-3\\Ca in situ were related to HPV-16. Non-oncogenic HPV were only found in CIN-1 biopsy results. Compared to histology, the sensitivity of cytology was 31.8%, the specificity 95.5%; the sensitivity of colposcopy for high-grade lesions/cervical cancer was 51.0%, specificity was 91.4% and the concordance with HPV testing was high.The results confirm an association of HR-HPV with precursor lesions for cervical cancer

    Non-carious cervical lesions (NCCL) are defined as the loss of tooth substance at the cemento-enamel junction and are caused by abrasion, erosion and/or occlusal overload. In this paper we proved that our fast swept source OCT system is a valuable tool to track the evolution of NCCL lesions in time. On several extracted bicuspids, four levels of NCCL were artificially created. After every level of induced lesion, OCT scanning was performed. B scans were acquired and 3D reconstructions were generated. The swept source OCT instrument used in this study has a central wavelength of 1050 nm, a sweeping range of 106 nm (measured at 10 dB), an average output power of 16 mW and a sweeping rate of 100 kHz. A depth resolution determined by the swept source of 12 μm in air was experimentally obtained. NCCL were measured on the B-scans as 2D images and 3D reconstructions (volumes). For quantitative evaluations of volumes, the Image J software was used. By calculating the areas of the amount of lost tissue corresponding to each difference of Bscans, the final volumes of NCCL were obtained. This swept source OCT method allows the dynamic diagnosis of NCCL in time.

    2010-09-01

    To assess the work performance and productivity impact of human papillomavirus (HPV). A cross-sectional study compared 94 employed women with clinically significant HPV-related cervical lesions with 118 healthy controls. Data were collected by self-administered web-based questionnaire. At-work performance limitations and productivity loss (presenteeism) and absenteeism were measured. Univariate and multivariate case-control group and clinical subgroup differences were tested. Based on adjusted mean scores, the HPV group had significantly more at-work limitations and productivity loss than controls (P = 0.009), higher absence rates (P = 0.002), and significantly more productivity loss because of absences (P = 0.007). At-work limitations varied in association with martial status (P = 0.025); at-work productivity loss was associated with years of education (P = 0.039). HPV is costly for working women, their employers, and the economy.

  19. Interlimb Dynamic after Unilateral Focal Lesion of the Cervical Dorsal Corticospinal Tract with Endothelin-1

    Walther A. Carvalho

    2017-10-01

    Full Text Available Handedness is one of the most recognized lateralized behavior in humans. Usually, it is associated with manual superiority regarding performance proficiency. For instance, more than 90% of the human population is considered more skilled with the right hand, which is controlled by the left hemisphere, than with the left. However, during the performance of bimanual tasks, the two hands usually assume asymmetric roles, with one hand acting on objects while the other provides support, stabilizing the object. Traditionally, the role of the two hands is viewed as fixed. However, several studies support an alternate view with flexible assignments for the two hands depending on the task. The supporting role of the hand depends on a closed loop pathway based on proprioceptive inputs from the periphery. The circuit’s efferent arm courses through the dorsal corticospinal tract (dCST in rodents and terminate on spinal cord interneurons which modulate the excitability of motoneurons in the ventral horn. In the present work, we developed an experimental model of unilateral lesion targeting the cervical dCST with microinjections of the vasoconstrictor endothelin-1 (ET-1 to evaluate the degree of flexibility of forelimb assignment during a food manipulation task. Our results show that just 3 days after unilateral corticospinal tract (CST injury in the cervical region, rats display severe motor impairment of the ipsilateral forepaw together with a remarkable reversal of motor assignment between the forelimbs.

    Ahmadi, Shahrzad; Goudarzi, Hossein; Jalilvand, Ahmad; Esmaeilzadeh, Abdolreza

    2017-12-29

    Objective: Cervical cancer is one of the most common cancers among women all over the world, and main cause is persistent infection with high risk human papillomavirus (HPV) strains. It has been reported that the distribution and prevalence of HPV types varies by geographical region, so that this is important for prevention by type-specific vaccines. The aim of current study was to determine the genotype distribution of HPV using the INNO-LiPA genotyping assay in Zanjan province, North West Iran. Methods: A total of 112 formalin-fixed paraffin embedded (FFPE) tissue samples from cases of low-grade intraepithelial lesion (LSIL), high-grade intraepithelial lesion (HSIL) and squamous cell carcinoma (SCC) were collected. The polymerase chain reaction (PCR) was used to amplify DNA for genotyping. Results: Among the 112 samples from females (ranging from 20 to 69 years, mean age 43.8 ± 10.1) tested for HPV DNA, 50 samples were positive. Based on results of genotyping, most common HPV genotypes were HPV18 (48%) followed by HPV-6 (24%), HPV73 (16%), HPV-51(8%), HPV-31(8%), HPV-16 (8%), HPV-56 (4%), HPV-44 (4%). Conclusion: While HPV infection is the major etiological factor for cervical cancer, presence was relatively low in our survey. In the positive cases, however, HPV18 was the most common in line with many other populations. The fact that types vary among different populations must clearly be taken into account in design of vaccines for our country. Creative Commons Attribution License

    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.

    2018-05-06

    Objective: To study the prevalence of high-risk HPV (HR HPV) in women who accepted cervical cancer screening in Beijing and its distribution in cervical precancerous lesions. Methods: From January 2014 to March 2015, all women aged 35-64 years old and received free screening in institutions of cervical cancer in Beijing were recruited. Stratified cluster random sampling method was used in selecting 31 091 women for gynecological examination and genotyping of HR-HPV. Those positive for HR-HPV (except for HPV 16/18) were examined for cervical cell. For those atypical squamous cells of uncertain significance (ASCUS) and above, who were positive for HPV 16/18 and with uncertain results for cervical cell, were transferred for colposcopy examination. For those with suspicious or abnormal results for colposcopy, were transferred for histopathology. The prevalence of HR-HPV, cervical cancer and precancerous lesions among the participants were analyzed. Results: Totally 31 091 women aged from 35-year-old to 64-year-old, with 44.3% (13 780 women) in the 35-49 age group and 55.7% (17 311 women) in the 50-64 age group. 66.1% (20 536 women) were rural women. The infection rate of HR-HPV was 7.4%(2 305 cases) among the women. High-risk infection rates of HPV except HPV 16/18 were 5.7% (1 758 cases), and multi-infection rate was 1.5% (477 cases). The highest infection rate was 7.9% (1 044 cases) among the 45-49 year-old and 50-54 year-old age groups (χ(2)=14.07, P= 0.015). The rate in rural women was significantly higher than that of the urban women (6.2%, 507 cases; 7.9%, 1 798 cases) (χ(2)=25.75, Page group.

    2013-08-01

    Although there is a high prevalence of noncarious cervical lesions (NCCLs), the etiology of these lesions remains contentious. To evaluate the combined effects of cyclic fatigue stress and biocorrosion activity on NCCLs. Extracted premolar teeth were allocated into four groups (N = 10). Two groups were cyclically fatigue loaded (100 N; 72 cycles per minute; 9,200 cycles) and placed in either hydrochloric acid gel (pH = 0.1) or orange juice (pH = 4). The other two groups were stored in identical chemical solutions without fatigue load. The buccal-lingual width of each tooth was measured before and after testing. The depth of biocorrosion, normalized by the percentage change in buccolingual width, normalized by time (hour) was calculated. The data were analyzed using a two-way analysis of variance and Tukey's HSD multiple comparison test (α = 0.05). Mean (SD) of the depth of biocorrosion values were as follows: teeth receiving fatigue loading with hydrochloric acid gel exposure (1.003%/hour [0.063]) revealed a significantly higher depth of biocorrosion than the fatigue-loaded group with orange juice exposure (0.511%/hour [0.281]) (p biocorrosion than the group with orange juice (0.009%/hour [0.004]) (p biocorrosion than either group without fatigue loading (p biocorrosion had a significant effect on the depth of the NCCLs. In order to manage the destructive NCCLs lesions properly, it is essential to understand the etiology of these lesions. The present study indicated that the combined mechanisms of cyclic fatigue stress and biocorrosion could contribute to the formation of NCCLs. © 2013 Wiley Periodicals, Inc.

    Magnetic resonance (MR) images of 13 intracranial mass lesions taken with the intravenous administration of gadolinium-DTPA were evaluated in comparison with precontrast computed tomography (CT), postcontrast CT, and precontrast MR. In the MR images taken with Gd-DTPA, tumor delineation improved in eight of 13 cases (62%) in comparison with precontrast MR images, and in seven of 13 cases (54%) in comparison with the overall evaluation of precontrast CT, postcontrast CT, and precontrast MR images. Tumor demarcation was unchanged in the remaining cases; no deterioration was observed with Gd-DTPA administration. MR imaging with Gd-DTPA should be performed to better evaluate the extent of intracranial mass lesions and to provide additional information. (author)

    1988-01-01

    CT findings of 35 patients with proven 31 parotid gland mass lesions (23 benign tumors, 5 malignant tumors, 3 inflammatory diseases) and 4 infraauricular lymphadenopathy (2 inflammatory nodes, 2 neoplastic nodes) were reviewed. CT accurately diagnosed the parotid origin in 29 of 31 parotid gland diseases. In all four patients with infraauricular lymphadenopathy, differentiation from parotid tumor was difficult. CT differentiation between superficial and deep lobe tumors agreed with surgical findings in 18 of 21 parotid gland tumors. Twenty out of 23 benign parotid gland tumors appeared as discrete masses with smooth margins. All five malignant parotid gland tumors appeared as poorly defined masses. It is concluded that when a tumor is located in the superficial lobe and appears as a sharply circumscribed mass on plain CT, it should be diagnosed as a benign lesion and contrast CT is not required. Secondly, contrast CT would be beneficial when a tumor is indistinct, or located in the deep portion of the parotid gland on plain CT. Finally, CT-sialography is considered unnecessary in the diagnosis of parotid masses. (author)

    This study aims to evaluate and to compare the performance of cervical digital photography (CDP) to the visual inspection with acetic acid (VIA) and visual inspection with Lugol's iodine (VILI) methods for screening the uterine cervix cancer and its precursor lesions in developing countries. A cross-sectional study was performed in Brazil. 176 women were evaluated by VIA, VILI, CDP with acetic acid and CDP with Lugol's iodine. Kappa statistic was used to estimate the interobserver and intermethod agreement. Sensitivity, specificity and diagnostic accuracy of the four methods (VIA, VILI, CDP with acetic acid, CDP with Lugol's iodine) was calculated. Interobserver agreement for CDP with acetic acid was K = 0.441 and for CDP with Lugol's iodine was K = 0.533; intermethod agreement of VIA and CDP with acetic acid, K = 0.559; and of VILI and CDP with Lugol's iodine, K = 0.507. Sensitivity and specificity of CDP with acetic acid were 84.00 and 95.83 %, and of CDP with Lugol's iodine were 88.00 and 97.26 %, respectively. The diagnostic accuracy of CDP with acetic acid and CDP with Lugol's iodine was 92.78 and 94.90 %, respectively. This was the first study to assess the CDP with Lugol's iodine performance, which had similar performance to the CDP with acetic acid. CDP is considered a promising method for screening the uterine cervix cancer and its precursor lesions in developing countries.

    2015-01-01

    To identify the associated factors of cervical pre-malignant lesions among the married fisher women residing in the coastal areas of Sadras, Tamil Nadu. The study was conducted in five fishermen communities under Sadras, a coastal area in Tamil Nadu, India. Two hundred and fifty married fisher women residing in the area. Quantitative descriptive approach with a cross-sectional study design was used. Data were collected using a structured interview schedule for identifying the associated factors and Pap smear test was performed for identifying the pre-malignant cervical lesions among the married fisher women. Data were analyzed using descriptive and inferential statistics. 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. 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.

    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.

    To evaluate the short-term consequences and cost-effectiveness associated with the use of novel biomarkers to triage young adult women with minor cervical cytological lesions. Model-based economic evaluation using primary epidemiological data from Norway, supplemented with data from European and American clinical trials. Organised cervical cancer screening in Norway. Women aged 25-33 years with minor cervical cytological lesions detected at their primary screening test. We expanded an existing simulation model to compare 12 triage strategies involving alternative biomarkers (i.e. reflex human papillomavirus (HPV) DNA/mRNA testing, genotyping, and dual staining) with the current Norwegian triage guidelines. The number of high-grade precancers detected and resource use (e.g. monetary costs and colposcopy referrals) for a single screening round (3 years) for each triage strategy. Cost-efficiency, defined as the additional cost per additional precancer detected of each strategy compared with the next most costly strategy. Five strategies were identified as cost-efficient, and are projected to increase the precancer detection rate between 18 and 57%, compared with current guidelines; however, the strategies did not uniformly require additional resources. Strategies involving HPV mRNA testing required fewer resources, whereas HPV DNA-based strategies detected >50% more precancers, but were more costly and required twice as many colposcopy referrals compared with the current guidelines. Strategies involving biomarkers to triage younger women with minor cervical cytological lesions have the potential to detect additional precancers, yet the optimal strategy depends on the resources available as well as decision-makers' and women's acceptance of additional screening procedures. Women with minor cervical lesions may be triaged more accurately and effectively using novel biomarkers. © 2016 Royal College of Obstetricians and Gynaecologists.

    Chromosome 3 amplification affecting the 3q26 region is a common genomic alteration in cervical cancer, typically marking the transition of precancerous intraepithelial lesions to an invasive phenotype. Though potential 3q encoded target genes of this amplification have been identified, a functional correlation of potential oncogenic function is still missing. In this study, we investigated copy number changes and the expression level of SEC62 encoded at 3q26.2 as a new potential 3q oncogene in dysplastic cervical lesions and analyzed its role in cervical cancer cell biology. Expression levels of Sec62 and vimentin were analyzed in liquid based cytology specimens from 107 women with varying grades of cervical dysplasia ranging from normal cases to cancer by immunofluorescence cytology. Additionally, a subset of 20 representative cases was used for FISH analyses targeting SEC62. To further explore the functional role of Sec62 in cervical cancer, HeLa cells were transfected with a SEC62 plasmid or SEC62 siRNA and analyzed for their proliferation and migration potential using real-time monitoring and trans-well systems as well as changes in the expression of EMT markers. FISH analyses of the swabbed cells showed a rising number of SEC62 gains and amplifications correlating to the grade of dysplasia with the highest incidence in high grade squamous intraepithelial lesions and squamous cell carcinomas. When analyzing the expression level of Sec62 and vimentin, we found a gradually increasing expression level of both proteins according to the severity of the dysplasia. In functional analyses, SEC62 silencing inhibited and SEC62 overexpression stimulated the migration of HeLa cells with only marginal effects on cell proliferation, the expression level of EMT markers and the cytoskeleton structure. Our study suggests SEC62 as a target gene of 3q26 amplification and a stimulator of cellular migration in dysplastic cervical lesions. Hence, SEC62 could serve as a potential

    Early detection of breast cancer from the periodic screening of asymptomatic women could reduce breast cancer mortality by at least 40%. The authors are developing a computerized scheme for the detection of mass lesions in digital mammograms as an aid to radiologists in such high volume screening programs. Based on left-right architectural symmetry and gray-level histogram analysis, bilateral subtraction of left and right breast images is performed. False-positive detections included in bilateral-difference images are reduced with various images feature-extraction techniques. The database involves clinical film mammograms digitized by a TV camera and analyzed on a Micro-VAX workstation. Among five different bilateral subtraction techniques investigated, a nonlinear approach provided superior lesion enhancement. Feature-extraction techniques reduced substantially the remaining false-positives. Preliminary results, for 32 pairs of clinical mammograms, yielded a true-positive rate of approximately 95% with a false-positive rate of about 2 per image

  15. Can a Morel-Lavallée lesion be misdiagnosed as a mass like lesion?

    Lee, Yoon Jae; Kim, Jun Hyeok; Kim, Ji Young; Han, Hyun Ho

    2017-12-01

    The Morel-Lavallée lesion (MLL) is a post-traumatic closed soft tissue degloving injury. Common complaints of MLL patients are a haematoma or fluid collection on the trunk or the lower extremity. However, the authors introduce unique cases of MLL that present an atypical appearance. The fluid collection was not apparent, and the capsule formation was not detected on preoperative image study. The main complaint of patients was the uncomfortable mass-like lesion that was regarded as a simple benign lump. The purpose of this case study is to introduce the atypical cases of MLL and to help other physicians make accurate diagnosis based on trial and error of our cases. © 2017 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

    Full Text Available SurePath specimens from women referred to colposcopy were treated with Aptima Transfer Solution (ATS before testing in Aptima HPV (AHPV and Aptima HPV 16, 18/45 (AHPV-GT assays. Untreated SurePath specimens were tested with the cobas HPV test. PreservCyt specimens were assessed for cytology and tested with AHPV. High-grade cervical intraepithelial neoplasia lesions served as the reference standard. Excellent agreement (95.5%; k=0.91 was observed for ATS-treated SurePath specimens between Tigris and Panther systems and between the PreservCyt and ATS-treated SurePath specimens (91.1%, k=0.81 with the AHPV assay on Tigris. Agreement between the AHPV and cobas assays with SurePath specimens was substantial (89.9%, k=0.80. AHPV sensitivity for CIN2+(n=147 was 91.2% for SurePath and PreservCyt. Cobas HPV sensitivity was 93.9% for SurePath specimens. AHPV testing of SurePath specimens was more specific (59.4% than cobas (54.7% (p<0.001. Detection and genotyping showed similar absolute and relative risks. ATS-treated SurePath specimens tested with AHPV and AHPV-GT assays showed similar performance with greater specificity than cobas HPV on SurePath specimens. Similar overall results were seen using a CIN3 disease endpoint. Keywords: Human papillomavirus, SurePath, PreservCyt, Cervical intraepithelial neoplasia, CIN2+, Aptima transfer solution (ATS

    Ruschel, V C; Shibata, S; Stolf, S C; Chung, Y; Baratieri, L N; Heymann, H O; Walter, R

    To evaluate the clinical performance of Scotchbond Universal (3M Oral Care) and Prime & Bond Elect (Dentsply Sirona) in the restoration of noncarious cervical lesions (NCCLs). This was a randomized controlled clinical trial involving 63 subjects. Two hundred and three NCCLs were restored using Scotchbond Universal and Prime & Bond Elect using both an etch-and-rinse and a self-etch technique. Lesions were notch-shaped NCCLs, and the restorations were placed without any mechanical retention. Restorations were finished immediately after placement and scored with regard to retention, marginal discoloration, marginal adaptation, and secondary caries. Similar assessment of the restorations was performed 18 months after placement. Logistic regression was performed for each outcome separately with a compound symmetric variance-covariance structure assumed to consider a correlation of restorations within subjects. All analyses were conducted using SAS version 9.4 (SAS Inc). One hundred and fifty-eight teeth (77.8% of the restorations placed) in 46 subjects (73% of subjects enrolled) were available for the 18-month follow-up. A statistically significant difference was reached only for the comparison Scotchbond Universal/self-etch (SU_SE) and Prime & Bond Elect/etch-and-rinse (PBE_E&R) groups ( p=0.01), where a restoration with SU_SE was 66% less likely to maintain a score of Alpha for marginal discoloration than a restoration performed with PBE_E&R. Scotchbond Universal and Prime & Bond Elect presented acceptable clinical performance after 18 months of clinical service. However, Scotchbond Universal, when applied with a self-etch approach, did demonstrate a relatively high level of marginal discoloration when compared to the other groups.

    In patients with spinal cord injury after blunt trauma, several studies have observed a correlation between neurologic impairment and radiologic findings. Few studies have been performed to correlate spinal cord injury with ligamentous injury. The purpose of this study was to retrospectively evaluate whether ligamentous injury or disk disruption after spinal cord injury correlates with lesion length. We retrospectively reviewed 108 patients diagnosed with traumatic spinal cord injury after cervical trauma between 1990-2011. Plain films, CT, and MR imaging were performed on patients and then reviewed for this study. MR imaging was performed within 96 hours after cervical trauma for all patients. Data regarding ligamentous injury, disk injury, and the extent of the spinal cord injury were collected from an adequate number of MR images. We evaluated anterior longitudinal ligaments, posterior longitudinal ligaments, and the ligamentum flavum. Length of lesion, disk disruption, and ligamentous injury association, as well as the extent of the spinal cord injury were statistically assessed by means of univariate analysis, with the use of nonparametric tests and multivariate analysis along with linear regression. There were significant differences in lesion length on T2-weighted images for anterior longitudinal ligaments, posterior longitudinal ligaments, and ligamentum flavum in the univariate analysis; however, when this was adjusted by age, level of injury, sex, and disruption of the soft tissue evaluated (disk, anterior longitudinal ligaments, posterior longitudinal ligaments, and ligamentum flavum) in a multivariable analysis, only ligamentum flavum showed a statistically significant association with lesion length. Furthermore, the number of ligaments affected had a positive correlation with the extension of the lesion. In cervical spine trauma, a specific pattern of ligamentous injury correlates with the length of the spinal cord lesion in MR imaging studies

    To explore the value of whole-lesion apparent diffusion coefficient (ADC) histogram and texture analysis in predicting tumor recurrence of advanced cervical cancer treated with concurrent chemo-radiotherapy (CCRT). 36 women with pathologically confirmed advanced cervical squamous carcinomas were enrolled in this prospective study. 3.0 T pelvic MR examinations including diffusion weighted imaging (b = 0, 800 s/mm 2 ) were performed before CCRT (pre-CCRT) and at the end of 2nd week of CCRT (mid-CCRT). ADC histogram and texture features were derived from the whole volume of cervical cancers. With a mean follow-up of 25 months (range, 11 ∼ 43), 10/36 (27.8%) patients ended with recurrence. Pre-CCRT 75th, 90th, correlation, autocorrelation and mid-CCRT ADC mean , 10th, 25th, 50th, 75th, 90th, autocorrelation can effectively differentiate the recurrence from nonrecurrence group with area under the curve ranging from 0.742 to 0.850 (P values range, 0.001 ∼ 0.038). Pre- and mid-treatment whole-lesion ADC histogram and texture analysis hold great potential in predicting tumor recurrence of advanced cervical cancer treated with CCRT.

  1. The performance of multimodal hyperspectral spectroscopy in the detection of precancerous cervical lesions

    Trahmono; Lusiana, N.; Indarti, J.

    2017-08-01

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

    Full Text Available 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.

    2011-09-01

    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.

    Full Text Available Malignant mixed Mullerian tumors are composed of a mixture of sarcoma and carcinoma. The carcinomatous element is usually glandular, whereas the sarcomatous element may resemble normal endometrial stroma (homologous or so-called carcinosarcoma. Here, we present a homologous type of malignant mixed Mullerian tumor of the uterus that presented as a cervical mass. We describe a 55-year-old patient who had a cervical mass arising from the uterus. We performed total abdominal hysterectomy and bilateral salpingo-oophorectomy and surgical staging (including (peritoneal washings, suspicious areas or peritoneal surfaces sampled, infracolic omental sampling, pelvic and paraaortic lymph node sampling, and appendectomy. Carcinosarcomas of the uterine cervix are extremely rare, and when a post-menopausal woman with a cervical mass is admitted to the gynecology clinic, the physician should keep in mind that the mass might be a carcinosarcoma.

    Stoian, M; Repanovici, R; Corniţescu, F

    1995-01-01

    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.

    1984-01-01

    Careful palpation, plain X-rays and angiography are useful in the diagnosis of lateral cervical masses, but accurate preoperative evaluation sometimes needs further examinations. Recently several new auxiliary procedures have become available such as RI-scintigraphy, Ultrasound, and CT-scanning but even these may not be sufficient when used singly. When all these procedures were combined preoperatively in the case of lateral cervical masses and the results were compared with the findings at time of surgery and the pathology of the extirpated masses, acurate preoperative diagnose were possible.

  10. HPV prevalence and type distribution in women with or without cervical lesions in the Northeast region of Romania

    2011-01-01

    Background Cervical cancer is a major public health problem worldwide. While Romania has the highest incidence of cervical cancer in Europe, the prevalence of HPV has not been evaluated. We report the first data on HPV prevalence and type distribution in Northeast Romania. Methods HPV prevalence and genotype distribution was investigated in 514 consecutively women with or without cervical lesions in Northeast Romania. Genotyping was performed with Linear Array Genotyping/Roche kit. Results In our study group, 192/514 (37.4%) patients were positive for HPV (infected with single and with multiple HPV types). Most frequent types were: 16 (10.5%), 53 (5.44%), 51 (5.05%), 52 (4.08%) 18 (2.91%) and 31 (2.73%). Conclusions Infection with high risk types of HPV is common in Northeast Romania. Enhanced and systematic screening for cervical cancer is needed. Our results call for the implementation of a National HPV vaccine program in Romania. PMID:22192090

  11. HPV genotype distribution and anomalous association of HPV33 to cervical neoplastic lesions in San Luis Potosí, Mexico.

    DelaRosa-Martínez, Raúl; Sánchez-Garza, Mireya; López-Revilla, Rubén

    2016-01-01

    The association of human papillomavirus (HPV) types to neoplastic lesions increase as a function of their oncogenicity and the duration of the infection since lesion severity progresses from low-grade to high-grade and cancer. In an outbreak, the prevalence of the HPV type involved would increase and the proportion of the associated low-grade lesions would predominate over severe lesions. In this study, the prevalence of HPV types and their association to neoplastic lesions was determined in women subjected to colposcopy in San Luis Potosí, Mexico. DNA from high-risk (HR) and low-risk (LR) HPV types was identified by E6 nested multiplex PCR in cervical scrapes from 700 women with normal cytology, atypical squamous cells of undetermined significance (ASCUS), low-grade squamous intraepithelial lesions (LSIL), high-grade squamous intraepithelial lesions (HSIL) or invasive cervical cancer (CC). Overall HPV-DNA prevalence was 67.7 %, that of HR-HPV was 63.1 %, and that of LR-HPV was 21.3 %. The highest prevalence (78.2 %) occurred in the 15-24 year group, whereas that of single infections was 52 % and that of multiple infections (i.e., by 2-6 HPV types) was 48 %. The most prevalent HR types were HPV33 (33.1 %), HPV16 (16.6 %), HPV18 and HPV51 (6.7 % each). HR-HPV prevalence was 29.6 % in normal cytology, 26.7 % in ASCUS, 63.3 % in LSIL, 68.2 % in HSIL, and 90.5 % in CC. Three prevalence trends for HR-HPV types were found in neoplastic lesions of increasing severity: increasing (LSIL  CC) for HPV33. Two-thirds of the women subjected to colposcopy from 2007 to 2010 in San Luis Potosí have HPV infections which predominate in the 15-24 years group. Around half of the infections are by one viral type and the rest by 2-6 types. HPV33 is the most prevalent type, followed by HPV16. Overall HR-HPV prevalence increases with the severity of neoplastic lesions. HPV33 prevalence is highest in LSIL and its U-shaped trend with progressing neoplastic lesions

  12. Treatment of Gingival Recessions Associated to Cervical Abrasion Lesions with Subepithelial Connective Tissue Graft: A Case Report

    Deliberador, Tatiana M.; Bosco, Alvaro F.; Martins, Thiago M.; Nagata, Maria J. H.

    2009-01-01

    Extensive gingival recessions associated with cervical abrasions are common among the population. Several different surgical and/or restorative therapies have been proposed to correct these lesions. This manuscript reports the treatment of multiple gingival recessions associated to cervical abrasions. The procedure involved the utilization of subepithelial connective tissue graft (SCTG) combined with coronally advanced flap onto a previously restored root surface. At the postoperative follow-up visits, the success of the restorative/surgical approach was confirmed by the absence of bleeding to probing and periodontal pockets as well as presence of gingival tissue with normal color, texture and contouring. After 18 months of follow-up, the clinical conditions are stable with satisfactory root coverage and periodontal health. An excellent esthetical outcome was achieved and the patient is satisfied with case resolution. PMID:19826605

  13. Integration, viral charge and E2 mRNA levels in the progresion of intraepitelial cervical lesions

    2018-01-01

    Full Text Available It is important to distinguish among squamous intraepithelial lesions (SIL those associated with increased risk cervical cancer. Our aim was to evaluate if the expression level of gen E2 in women with SIL and evidence of viral integration is associated to the grade of lesion. Cervical scrapes HPV16 positive from 19 women with normal histology, 45 women with low-grade SIL (LSIL and 45 women with high-grade SIL (HSIL were analyzed. Real-time PCR was used to quantify the mRNA of E2 and E2 and E6 genes to calculate viral load (E6 and the ratio E2/E6 to assess viral integration. Similar frequencies of E2 expression were found in LSIL and HSIL15/45 (33 %, the frequency in women without SIL was lower 3/19 (15.8 %, and all cases with E2 gene expression had mixed episomal and integrated viral DNA. The viral load increased significantly with the grade of SIL (p= 0.049, while E2/E6 ratio decreased (p=0.049. The ROC analysis showed low capacity of the three viral parameters analyzed to distinguish between low and high grade SIL. In conclusion although SIL with mixed and integrated viral DNA with E2 expression could be at lower risk of progression, and viral load and integration were associated with higher severity of the lesion, its clinical value as biomarkers of HSIL is limited.

    Full Text Available Summary: A community-based cross-sectional study was conducted in brothel-based sex workers of West Bengal, Eastern India, to determine their oncogenic human papillomavirus (HPV status and the presence of pre-cancerous lesions. A total of 229 sex workers from three districts of West Bengal participated in the study. All the study participants were interviewed with the aid of a pre-tested questionnaire to determine their sociodemographics, risk behaviour and risk perceptions after obtaining informed verbal consent. The interview was followed by collection of cervical cells from all participants using a disposable vaginal speculum and cervical cytobrush. Oncogenic HPV DNA was detected by real-time polymerase chain reaction (PCR. A simultaneous Papanicolaou test (‘Pap smear’ was performed to detect cervical cytological abnormalities. Overall, the prevalence of oncogenic HPV was found to be 25% (58/229 among the studied population. A subset (n = 112 of the sample was tested separately to determine the existence and magnitude of HPV genotypes 16 and 18. The results showed that genotype 16 was prevalent in 10% (11/112, genotype 18 in 7% (8/112 and both genotype 16 and 18 in 7% (8/112. The HPV prevalence rate showed a decreasing trend with age, being 71.4% in the 10–19 years age group, 32.3% in the 20–29 years age group, 18.3% in the 30–39 years age group and 2.5% in the ≥40 years age group (statistically significant differences, P ≤ 0.00001. Considering the duration of sex work, oncogenic HPV prevalence was found to be 55% (n = 21 and 19% (n = 35 in sex workers with a sex working duration of ≤1 year and >1 year, respectively. This difference was found to be statistically significant both by univariate and multivariate analysis. In this study, it was observed that sex workers with an average number of daily clients of six or more had an HPV prevalence of 67% (n = 6, those with four to five clients had a prevalence of 45% (n

    Although the natural history of cervical and oral human papillomavirus infection has been intensively investigated in the past years, the ability of this virus to infect oral and genital mucosae in the same individual and its potential to co-infect both cervical and oral mucosa are still unclear. The aim of the authors was to assess the presence of oropharyngeal human papillomavirus infection in women with cervical lesions in the South-Eastern Hungarian population. The total of 103 women have been included in the study between March 1, 2013 and January 1, 2015. Brushing was used to collect cells from the oropharyngeal mucosa. Human papillomavirus DNA was detected using polymerase chain reaction, and Amplicor line blot test was used for genotyping. Oropharyngeal human papillomavirus infection was detected in 2 cases (3%). The detected genotypes were 31, 40/61 and 73 in the oropharyngeal region. The results indicate that in women with cervical lesions oropharyngeal human papillomavirus infection rarely occurs.

    2015-07-17

    OBJECT The progression of cervical ossification of the posterior longitudinal ligament (OPLL) can lead to increase in the size of the OPLL mass and aggravation of neurological symptoms. In the present study, the authors aimed to analyze the progression of cervical OPLL by using CT imaging, elucidate the morphology of OPLL masses, and evaluate the factors associated with the progression of cervical OPLL. METHODS Sixty patients with cervical OPLL were included. All underwent an initial CT examination and had at least 24 months' follow-up with CT. The mean duration of follow-up was 29.6 months. Fourteen patients (Group A) had CT evidence of OPLL progression, and 46 (Group B) did not show evidence of progression on CT. The 2 groups were compared with respect to the following variables: sex, age, number of involved segments, type of OPLL, and treatment methods. The CT findings, such as the connection of an OPLL mass with the vertebral body and formation of trabeculation in the mass, were evaluated. RESULTS Sex and treatment modality were not associated with OPLL progression. The mean age of the patients in Group A was significantly lower than that in Group B (p = 0.03). The mean number of involved segments was 5.3 in Group A and 3.6 in Group B (p = 0.002). Group A had a higher proportion of cases with the mixed type of OPLL, whereas Group B had a higher proportion of cases with the segmental type (p = 0.02). A connection between the vertebral body and OPLL mass and trabeculation formation were more common in Group B (p cervical OPLL is associated with younger age, involvement of multiple levels, and mixed-type morphology. OPLL masses that are contiguous with the vertebral body and have trabecular formation are useful findings for identifying masses that are less likely to progress.

    In the cervical disc disease, computed tomography (CT) myelographic and conventional myelographic findings were surgically confirmed. The authors classified the disc protrusion into two types, and demonstrated the characteristic features of these two types in CT myelography and conventional myelography. Moreover, the correlation with the localization of the disc protrusion and the laterality of the myelopathy are discussed. All cases were obtained using a late generation scanner and the patient in the supine position with the neck in the neutral position. Using conventional myelography, all examinations were obtained with the neck in a flexion, neutral and extended positions. Twenty-two patients with cervical disc disease operated on by an anterior approach were studied by CT myelography and conventional myelography. According to the style of the compression on the spinal cord, the cervical disc protrusion was classified into two main groups, the subligamentous type and epiligamentous type. This study included 10 patients of the subligamentous type and 12 patients of the epiligamentous type. The localization of the disc protrusion and the laterality of the myelopathy often corresponded with each other. Not only the localization of the lesion, but also the pincer effect, especially the oblique pincer effect, which is reinforced by dynamic factors, are important in the understanding of the manifestations of myelopathy. In the subligamentous type, the main cause of the myelopathy is considered to be the mechanical pressure by the prolapsed nucleus pulposus. In the epiligamentous type, on the other hand, it is believed to be the pincer effect, reinforced by dynamic factors. (author)

  20. Congenital cervical cysts, sinuses, and fistulae in pediatric surgery.

    LaRiviere, Cabrini A; Waldhausen, John H T

    2012-06-01

    Congenital cervical anomalies are essential to consider in the clinical assessment of head and neck masses in children and adults. These lesions can present as palpable cystic masses, infected masses, draining sinuses, or fistulae. Thyroglossal duct cysts are most common, followed by branchial cleft anomalies and dermoid cysts. Other lesions reviewed include median ectopic thyroid, cervical teratomas, and midline cervical clefts. Appropriate diagnosis and management of these lesions requires a thorough understanding of their embryology and anatomy. Correct diagnosis, resolution of infectious issues before definitive therapy, and complete surgical excision are imperative in the prevention of recurrence. Copyright © 2012 Elsevier Inc.

    The burden of cervical cancer remains huge globally, more so in sub-Saharan Africa. Effectiveness of screening, rates of recurrence following treatment and factors driving these in Africans have not been sufficiently studied. The purpose of this study therefore was to investigate factors associated with recurrence of cervical intraepithelial lesions following thermo-coagulation in HIV-positive and HIV-negative Nigerian women using Visual Inspection with Acetic Acid (VIA) or Lugol's Iodine (VILI) for diagnosis. A retrospective cohort study was conducted, recruiting participants from the cervical cancer "see and treat" program of IHVN. Data from 6 sites collected over a 4-year period was used. Inclusion criteria were: age ≥18 years, baseline HIV status known, VIA or VILI positive and thermo-coagulation done. Logistic regression was performed to examine the proportion of women with recurrence and to examine factors associated with recurrence. Out of 177 women included in study, 67.8 % (120/177) were HIV-positive and 32.2 % (57/177) were HIV-negative. Recurrence occurred in 16.4 % (29/177) of participants; this was 18.3 % (22/120) in HIV-positive women compared to 12.3 % (7/57) in HIV-negative women but this difference was not statistically significant (p-value 0.31). Women aged ≥30 years were much less likely to develop recurrence, adjusted OR = 0.34 (95 % CI = 0.13, 0.92). Among HIV-positive women, CD4 count thermo-coagulation occurs in a significant proportion of women. HIV-positive women with low CD4 counts are at increased risk of recurrent lesions and may be related to immunosuppression.

    Background: Cervical spine and intervertebral discs are potentially prone to functional disorders. 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. Materials 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 the neck were closely associated with the degenerative signs on the MR images

    Objective: To investigate the affection of lesion blood supply on apparent diffusion coefficient (ADC) of focal hepatic mass. Methods: Diffusion-weighted imaging (DWI) with different b values was performed in 87 patients with 159 focal hepatic lesions. ADCs of lesion, liver, spleen, gallbladder were measured in every case. Results: On DWI with small b value and small b value remainder, ADCs were affected by blood perfusion of tissues or lesions. The mean ADC of hypervascular lesions was significantly higher than that of hypovascular lesions on DWI with small b value, and hemoangiomas got the highest mean ADC. The mean ADC of hepatic cysts was not affected by b value. Conclusion: Blood perfusion affects ADC of tissue or focal hepatic lesion, particularly on DWI with small b value, and to some degree, DWI and ADC can reflect the blood supply of focal hepatic lesion

    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. 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. 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. 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

  6. Efficacy in Treatment of Cervical HrHPV Infection by Combination of Beta Interferon, and Herbal Therapy in Woman with Different Cervical Lesions

    Full Text Available Cervical dysplasia, a premalignant lesion that can progress to cervical cancer, is caused primarily by a sexually transmitted infection with an oncogenic strain of the human papillomavirus (HPV. The HPV infections are treated through destroying the clinical lesions: laser, cryotherapy, podophyllin. The hope is that by causing local tissue inflammation that the body will be stimulated to mount an antibody response and thereby prevent recurrence. In contrast to other prevention approaches, vaccines can reduce susceptibility in uninfected partners by stimulating the immune system. Aloe vera has also been reported to retard tumour growth and stimulate the immune response to viruses. A list of possible actions of propolis includes: antibacterial, antifungal, antiviral, antioxidant, anticarcinogenic, antithrombotic and immunomodulatory. Research on the possible role of some B vitamins in preventing cancer began in the last few decades, but however this complex have an influence on immune status. The aim of our study is to try to treat the HPV infection as confirmed cause of neoplastic transformation with some herbal therapy and interferon and to try define the guidelines in the management of the HPV positive patients. Goal of this paper is to search for evidence of efficacy of any treatment for HPV infection of the cervix mostly in woman with no concomitant CIN. Fifty five woman affected by HPV genital infection were enrolled in the study from September 2005 to April 2006. Patients were classified according to the results of the HPV testing prior and after the therapy. Patients were randomized into two groups: the first group was HPV positive woman treated with other than recommended therapy (n=20, (control group; the second group was pharmacologically treated with intravaginal administration of an interferon and aloe vera-propolis in recommended scheme (n=35 with treatment of the possible fungal or bacterial genital infection prior to the specific

    2017-01-01

    In South African breast care centres, full-field digital mammography units provide breast imaging services to symptomatic and asymptomatic women simultaneously. This study evaluated the technical exposure parameters of 800 mammograms of which 100 mammograms had obvious mass lesions in the fibro-glandular tissue. The average breast compression force of mammograms with mass lesions in the fibro-glandular tissue was 18.4% less than the average breast compression force of mammograms without mass lesions. The average mean glandular dose (MGD), tube potential (kV p ) and compressed breast thickness (CBT) values were 2.14 mGy, 30.5 kV p and 63.9 mm, respectively, for mammograms with mass lesions, and 1.45 mGy, 29.6 kV p and 56.9 mm, respectively, for mammograms without mass lesions. Overall, the average MGD and mean CBT of mammograms with mass lesion were significantly higher compared to those without mass lesions (p < 0.05), although there was no significant difference in their tube potentials (p > 0.05).

  8. Unicameral bone cyst of a cervical vertebral body and lateral mass with associated pathological fracture in a child. Case report and review of the literature.

    Snell, B E; Adesina, A; Wolfla, C E

    2001-10-01

    The authors present the case of a 10-year-old girl with a history of cervical trauma in whom a cystic lesion was found to involve all three columns of C-7 with evidence of pathological fracture. Computerized tomography scanning revealed a lytic lesion with sclerotic margins involving the left vertebral body, pedicle, lateral mass, and lamina of C-7 with an associated pathological compression fracture. Magnetic resonance imaging demonstrated mixed signal on both T1- and T2-weighted sequences, with cystic and enhancing solid portions. Magnetic resonance angiography demonstrated anterior displacement of the left vertebral artery at C-7. The patient underwent C-7 subtotal corpectomy and posterior resection of the tumor mass; anterior and posterior fusion were performed in which instrumentation was placed. Histological examination disclosed cystic areas lined by fibromembranous tissue with calcification and osteoid deposits consistent with unicameral bone cyst. Of the four previously reported cases of unicameral bone cysts in the cervical spine, none involved all three columns simultaneously or was associated with pathological fracture. The most common differential diagnostic considerations for cystic lesions in the spine are aneurysmal bone cyst, osteoblastoma, or giant cell tumor of bone. Unicameral bone cyst, in this location, although rare, must be considered in the differential diagnosis and may require resection and spinal reconstruction.

    Objectives To estimate efficacy of a visual triage of human papillomavirus (HPV)– positive women to either immediate cryotherapy or referral if not treatable (eg, invasive cancer, large precancers). Methods We evaluated visual triage in the HPV-positive women aged 25 to 55 years from the 10,000-woman Guanacaste Cohort Study (n = 552). Twelve Peruvian midwives and 5 international gynecologists assessed treatability by cryotherapy using digitized high-resolution cervical images taken at enrollment. The reference standard of treatability was determined by 2 lead gynecologists from the entire 7-year follow-up of the women. Women diagnosed with histologic cervical intraepithelial neoplasia grade 2 or worse or 5-year persistence of carcinogenic HPV infection were defined as needing treatment. Results Midwives and gynecologists judged 30.8% and 41.2% of women not treatable by cryotherapy, respectively (P cryotherapy. The proportion of women judged not treatable by a reviewer varied widely and ranged from 18.6%to 61.1%. Interrater agreement was poor with mean pairwise overall agreement of 71.4% and 66.3% and κ ’s of 0.33 and 0.30 for midwives and gynecologists, respectively. Conclusions In future “screen-and-treat” cervical cancer prevention programs using HPV testing and cryotherapy, practitioners will visually triage HPV-positive women. The suboptimal performance of visual triage suggests that screen-and-treat programs using cryotherapy might be insufficient for treating precancerous lesions. Improved, low-technology triage methods and/or improved safe and low-technology treatment options are needed. PMID:19509579

    2010-02-01

    To compare the clearance rate of HPV infection among women aged older than 30 years with biopsy-confirmed cervical low-grade squamous intraepithelial lesions (LSIL) 1 year after cryotherapy with the spontaneous clearance rate (observation). HPV DNA typing by polymerase chain reaction and reverse line blot hybridization were used to identify 14 high-risk types and 23 low-risk types. HPV DNA sequencing was also used for other types. Between December 2007 and March 2009, 100 women were recruited to the study and 60 cases had positive results on HPV testing. Twenty-nine patients were randomly allocated to the cryotherapy group and 31 to the observation group. At 1 year, 89.7% (26/29; 95% CI, 78.6-100%) of the cryotherapy group and 90.3% (28/31; 95% CI, 79.9-100%) of the observation group had negative results on HPV testing (0.6% difference; 95% CI, -15.8 to 14.6%, P=0.94). Cryotherapy failed to increase the clearance of prevalent HPV infections among women with LSIL, although in both arms the clearance rates were above 80%. However, in coupling with visual inspection with acetic acid as a single visit approach, its effect on prevention of HSIL and cervical cancer is still promising. Therefore, cryotherapy should not be withdrawn from such programs. Copyright 2009 Elsevier Ireland Ltd. All rights reserved.

  12. Is screen-and-treat approach suited for screening and management of precancerous cervical lesions in Sub-Saharan Africa?

    Fokom-Domgue, Joël; Vassilakos, Pierre; Petignat, Patrick

    2014-08-01

    The World Health Organization guidelines for screening and management of cervical precancerous lesions updated in 2013 made an emphasis on the use of the 'screen-and-treat' approach for cervical cancer prevention. In order to facilitate scaling-up in low income settings, most of these screen-and-treat strategies do not involve confirmatory biopsy. This yields a certain rate of overtreatment. In other words, a majority of people undergoing screen-and-treat intervention who are treated does not necessarily benefit from the treatment. Therefore, the issue of potential short term and long term complications of the recommended treatment procedures (cryotherapy and Loop Electrosurgical Excision Procedure) arises. This question has seldom been studied in resource poor countries, particularly in Sub-Saharan Africa where Human Immunodeficiency Virus infection is rampant in an epidemic fashion and where the procreative capacities are socially rewarding for women. We draw the attention of the scientific community and policy makers to the fact that the lack of evidence supporting the safety of these treatment procedures in African populations may have an impact on the acceptability of these strategies and therefore on the effectiveness of screening programs.

    2014-01-01

    To evaluate the clinical significance of atypical squamous cells of undetermined significance (ASCUS) in PAP test in post-menopausal women and compare with reproductive age women. A total of 367 patients who referred to our gynecologic oncology clinic were included to the study between September 2012 and August 2013. Data for 164 post-menopausal (group 1) and 203 pre-menopausal (group 2) women with ASCUS cytology were evaluated retrospectively. Immediate colposcopy and endocervical curettage was performed for both groups and conization for all women with a result suggestive of CIN2-3. Histopathological results and demographic features of patients were compared between the two groups. Mean age of the patients was 54.6±6.5 years in group 1 and 38±6.6 years in group 2. Some 14 (8.5%) of post- menopausal women and 36 (17.7%) of pre-menopausal women were current smokers (p=011). Totals of 38 (23.2%) post-menopausal and 64 (31.5%) pre-menopausal women were assessed for HPV-DNA. High risk HPV was detected in 7 (4.3%) and 21 (10.3%), respectively (p=0.029). Final histopathological results recorded were normal cervix, low grade cervical intra-epithelial neoplasia (CIN 1), and high grade cervical intra-epithelial neoplasia (CIN2-3). In group 1 results were 84.8%, 12.2% and 1.8%, respectively, and in group 2 were 71.9%, 23.2% and 4.9%. There were no cases of micro invasive or invasive cervical carcinoma in either group. Two cases were detected as endometrial carcinoma in the menopausal group (1.2%). In current study we found that preinvasive lesions were statistically significantly higher in pre-menopausal women than post- menopausal women with ASCUS. Cervicitis was more common in menopausal women. Therefore, we think that in case of ASCUS in a post-menopausal woman there is no need for radical management.

  15. Nuclear magnetic resonance tomography of the cervical canal

    Terwey, B.; Koschorek, F.; Jensen, H.P.

    1985-12-01

    170 patients with suspected lesions of the cervical part of the medulla were examined using nuclear magnetic resonance (NMR) tomography. 27 cases revealed no pathological changes in the regions of the cervical medulla, the cervical canal and of the cervical spine. 143 cases produced pathological findings whose diagnoses determined therapeutical approach. Verified pathological changes comprised anomalies of the cranio-cervical junction like basilar impression and Arnold-Chiari malformation, various types of cavity formation in the cervical medulla (syringomyelia, hydromyelia), demyelinization processes, intramedullary and extramedullary tumours, intervertebral disk degeneration processes, dislocation of intervertebral disks and spondylophytes with spinal stenoses. Sagittal sections in different functional positions allowed to demonstrate the biomechanical effects of extramedullary masses on the cervical medulla. However, proven tumours could not be differentiated successfully using histological methods. Nevertheless, NMR tomography will replace invasive methods like conventional cervical myelography and CT myelography in diagnostic clarification of diseases of the cervical medulla.

    Full Text Available Aims: We aimed to investigate the immunocytoexpression profiles of a novel assay ProEx C for topoisomerase II alpha (TOP2A and minichromosome maintenance protein 2 (MCM2 in abnormal interpreted smears. Settings and Design: Screening programs with Papanicolaou smear and high risk group human papilloma virus testing have yielded a dramatic reduction of cervical cancer incidence. However, both of these tests have limited specificity for the detection of clinically significant cervical high grade lesions. ProEx C for topoisomerase II alpha (TOP2A and minichromosome maintenance protein 2 (MCM2 has been considered to have tight association with high grade intraepithelial lesions. Materials and Methods: A total number of 54 SurePath cervical cytology specimens of patients previously interpreted as atypical squamous cells-undetermined significance (ASC-US, atypical squamous cells-cannot exclude high grade squamous intraepithelial lesion (ASC-H, low grade squamous intraepithelial lesion (LSIL, and high grade squamous intraepithelial lesion (HSIL were included in our study. Results and Conclusions: ProEx C was positive in 14 of HSILs (100%, 3 of 19 LSILs (16%, 2 of 4 ASC-Hs, and none of ASC-USs (0%. The ProEx C test showed very intense nuclear staining in all cytologically abnormal cells. Further studies are indicated to evaluate the diagnostic role of ProEx C.

    2015-01-01

    The Official Mexican Norm for the prevention, treatment and control of Cervical Cancer (CC) indicates that the Papanicolau (Pap) is the procedure for the detection of this neoplasia; therefore, it is of interest to know the prevalence of suspected cases by this technique in Mexican population. In this study, we show the diagnosed cases in the State of Jalisco, México. A retrospective study was made to the samples that arrived for their analysis to the Laboratorio Regional de Citología Exfoliativa (LARCE), of the Instituto Mexicano del Seguro Social (IMSS) in Guadalajara, Jalisco. We considered all cases from January 2010 to December 2012. We analyzed 188 095 cases, from which 5.3 % had a diagnosis of low dysplasia, 0.18 % of moderated dysplasia and 0.05 % of high dysplasia. Microinvasive and invasive cancer showed a low frequency (0.03 %). The frequency of abnormal findings identified by vaginal cervical cytology is relatively low. The number of inadequate and limited samples for cytological assessment is high; there is a high proportion of women attending for the first time in life to cytology evaluation in older age groups.

  19. Association between cervical lesion grade and micronucleus frequency in the Papanicolaou test

    2014-09-01

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

  20. Impact of visual inspection with acetic acid plus cryotherapy "see and treat" approach on the reduction of the population burden of cervical preinvasive lesions in Southeast Nigeria.

    2017-02-01

    The aim of this study is to determine the impact of visual inspection with acetic acid (VIA) plus immediate cryotherapy on the prevalence of VIA-detected cervical squamous intraepithelial lesion (SIL). Women in four rural communities in Southeast Nigeria were screened with VIA. Women who tested positive to VIA were offered either immediate cryotherapy or large loop excision of the transformation zone based on predetermined eligibility criteria. Cervical biopsies were taken before cryotherapy and examined by consultant histopathologists. All participants were rescreened 1 year later. The main outcome measures were population prevalence of cervical precancers before and after intervention, cure rates, and over-treatment rates. A total of 653 women participated in the study. The prevalence of cervical SIL before the intervention was 8.9% (58/653). The prevalence 1 year later was 1.4% (9/649). This gave an 84.3% reduction in the population prevalence of SIL. The reduction in cervical SIL prevalence was statistically significant (P = 0.0001). The prevalence of high-grade SIL reduced significantly from 4.1% (27/653) preintervention to 0.5% (3/649) 1 year postintervention (P = 0.0001). This gave an 87.8% reduction in the population prevalence of high-grade SIL. Cryotherapy provided a cure rate of 87.9% (95% confidence interval: 76.82-94.33). Population cervical cancer prevention using VIA plus immediate cryotherapy leads to significant reduction in the population prevalence of cervical SIL. This has the potential of being an acceptable supplement to cervical cytology for cervical cancer prevention in low-income populations.

    Dall'Orologio, Giovanni Dondi; Lorenzi, Roberta

    2014-10-01

    An equivalence randomized controlled trial within the subject was organized to evaluate the clinical long-term success of a new 2-step etch & rinse adhesive and a new nano-filled ormocer. 50 subjects, 21 males and 29 females aged between 21 and 65, were randomized to receive 150 restorations, 100 with the new restorative material, 50 with the composite as control, placed in non-carious cervical lesions with the same bonding system. The main outcome measure was the cause of failure at 8 years. Randomization was number table-generated, with allocation concealment by opaque sequentially numbered sealed and stapled envelopes. Subjects, examiner, and analyst were blinded to group assignment. Two interim analyses were performed. Data were analyzed by ANOVA and Cox test (P failures in the experimental group and four failures in the control group. The cumulative loss rate was 7% for both restorative materials, with the annual failure lower than 1%, without any statistically significant difference. There were two key elements of failure: the presence of sclerotic dentin and the relationship between lesion and gingival margin.

    Full Text Available Vertebral body may get displaced anterior or posteror with elements of rotation. However, burst cervical spine vertebral fracture may migrate anteriorly and posteriorly simultaneously. However anterior displaced fragment forming armor like mass is very rare. Similarly, the posteriorly propelled fragments migrating caudally and posterolaterally producing a large osseous mass inside spinal canal mimicking bony tumour causing severe cervical canal stenosis and presenting with marked myelopathy is extremely rare. To the best knowledge of authors, association of such traumatic dual pathology represents first of its kind in western literature, who was neglected early medical advice and presenting with marked compressive cervical myelopathy. She underwent successful surgical decompression with gradual recovery of spastic limb weakness and recovery of sensation. Authors also highlights the importance of early resuscitation and adequate maintainace of mean arterial pressure following acute spinal cord injury. Pertinent literature is briefly reviewed.

    Full Text Available CONTEXT AND OBJECTIVE: The latest update of the Bethesda System divided the category of atypical squamous cells of undetermined significance (ASCUS into ASC-US (undetermined significance and ASC-H (high-grade intraepithelial lesion cannot be ruled out. The aims here were to measure the prevalence of pre-invasive lesions (cervical intraepithelial neoplasia, CIN II/III and cervical cancer among patients referred to Instituto Fernandes Figueira (IFF with ASC-H cytology, and compare them with ASC-US cases. DESIGN AND SETTING: Cross-sectional study with retrospective data collection, at the IFF Cervical Pathology outpatient clinic. METHODS: ASCUS cases referred to IFF from November 1997 to September 2007 were reviewed according to the 2001 Bethesda System to reach cytological consensus. The resulting ASC-H and ASC-US cases, along with new cases, were analyzed relative to the outcome of interest. The histological diagnosis (or cytocolposcopic follow-up in cases without such diagnosis was taken as the gold standard. RESULTS: The prevalence of CIN II/III in cases with ASC-H cytology was 19.29% (95% confidence interval, CI, 9.05-29.55% and the risk of these lesions was greater among patients with ASC-H than with ASC-US cytology (prevalence ratio, PR, 10.42; 95% CI, 2.39-45.47; P = 0.0000764.

    1997-01-01

    To assess the characteristic features of MR findings which would be useful for the differentiation of various spinal diseases involving paraspinal soft tissue mass. We retrospectively reviewed MR findings in 31 cases(M : F = 20 : 11) of spinal disease in which paraspinal mass was involved. The breakdown of cases was as follows : spinal tuberculosis, 12; spinal metastasis, 13; multiple myeloma, 3; pyogenic spondylitis, 2; spinal aspergillosis, 1. The pattern of bone marrow invasion in spinal metastasis, multiple myeloma, spinal tuberculosis and aspergillosis was mixed; focal, homogeneously diffuse and inhomogeneously patterns were seen. Pyogenic spondylitis showed inhomogeneously diffuse invasion; an intravertebral abscess was seen in the only five cases of spinal tuberculosis. Vertebral posterior compartment invasion was observed in seven cases of spinal tuberculosis, two of multiple myeloma, the one case of spinal aspergillosis and in all 13 cases of spinal metastasis. This and multiple myeloma showed no disc space invasion, in any case, but all cases of infectious spondylitis showed such invasion. Peripheral rim-enhancement in the paravertebral mass was seen in 11 cases of spinal tuberculosis, one case of pyogenic spondylitis and the case of aspergillosis. Bilobate anterior epidural mass was noted in 60% of spinal tuberculosis cases, 36% of spinal metastasis and one case of pyogenic spondylitis. MR findings of spinal disease involving a paraspinal soft tissue mass were useful for differentiation

  9. Dose-mass inverse optimization for minimally moving thoracic lesions

    Mihaylov, I. B.; Moros, E. G.

    2015-05-01

    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

  11. A COMPARATIVE ANALYSIS OF SINGLE AND COMBINATION FEATURE EXTRACTION TECHNIQUES FOR DETECTING CERVICAL CANCER LESIONS

    S. Pradeep Kumar Kenny

    2016-02-01

    Full Text Available Cervical cancer is the third most common form of cancer affecting women especially in third world countries. The predominant reason for such alarming rate of death is primarily due to lack of awareness and proper health care. As they say, prevention is better than cure, a better strategy has to be put in place to screen a large number of women so that an early diagnosis can help in saving their lives. One such strategy is to implement an automated system. For an automated system to function properly a proper set of features have to be extracted so that the cancer cell can be detected efficiently. In this paper we compare the performances of detecting a cancer cell using a single feature versus a combination feature set technique to see which will suit the automated system in terms of higher detection rate. For this each cell is segmented using multiscale morphological watershed segmentation technique and a series of features are extracted. This process is performed on 967 images and the data extracted is subjected to data mining techniques to determine which feature is best for which stage of cancer. The results thus obtained clearly show a higher percentage of success for combination feature set with 100% accurate detection rate.

  12. Mass lesions in chronic pancreatitis: benign or malignant? An "evidence-based practice" approach.

    Gerstenmaier, Jan F

    2012-02-01

    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.

    Human papillomavirus (HPV) E2 and L1 proteins are expressed in cervical cells during the lytic stage of infection. Overexpression of p16 INK4A is a biomarker of HPV-associated cervical neoplasia. This study investigated antibodies to HPV16 E2, HPV16 L1, and p16 INK4A in sera from women with no squamous intraepithelial lesion (No-SIL) of the cervix, low-grade SIL, high-grade SIL, and cervical squamous cell carcinoma (SCC). HPV DNA was detected by polymerase chain reaction. Anti-E2, -L1, and -p16 INK4A antibodies in sera were determined by western blot. Among 116 samples, 69 (60%) were HPV DNA-positive. Percentages seropositive for anti-E2, -L1, and -p16 INK4A antibodies were 39.6, 22.4, and 23.3%, respectively. Anti-E2 antibody was significantly correlated with HPV DNA-positive cases. Eighty-seven women (75%) were regarded as infected with HPV, having at least one positive result from HPV DNA, L1, or E2 antibody. Antibody to p16 INK4A was associated with HPV infection (odds = 5.444, 95% CI 1.203-24.629, P = 0.028) and precancerous cervical lesions (odds = 5.132, 95% CI 1.604-16.415, P = 0.006). Interestingly, the concurrent detection of anti-E2 and -p16 INK4A antibodies was significantly associated with HPV infection (odds = 1.382, 95% CI 1.228-1.555, P = 0.044). These antibodies might be good candidate biomarkers for monitoring HPV-associated cervical lesion development to cancer.

  14. Resolución endovascular de lesiones por arma de fuego en la región cervical

    2016-01-01

    Full Text Available Introducción: Las heridas producidas por armas de fuego que comprometen la región cervical son materia de controversia en cuanto a cuál es el mejor método para tratarlas. La resolución endovascular de este tipo de patología ha cobrado gran relevancia en los últimos años debido al desarrollo de nuevos dispositivos y, consecuentemente, a la menor incidencia de complicaciones inherentes al procedimiento. Objetivo: Determinar el rol del tratamiento endovascular en la resolución de las lesiones cervicales por arma de fuego. Material y métodos: Se incluyeron 76 pacientes que sufrieron lesiones cervicales por arma de fuego, a los cuales se les realizó angiografía de los vasos supraaórticos para decidir la conducta a seguir. Resultados: Del total de 76 pacientes, 47 (61,8% presentaron una angiografía patológica; de estos, en 26 se decidió la resolución endovascular de la lesión, implantándose 1,1 stents por paciente. La estadía intrahospitalaria fue en promedio de 10,4 días. A los 30 días de seguimiento, 2 pacientes presentaron secuela neurológica y uno evolucionó con sepsis. En el seguimiento alejado con un promedio de 4 años se registró una muerte a los 117 días de realizado el procedimiento. Conclusiones: La intervención endovascular ha ganado mayor protagonismo con el desarrollo de nuevos dispositivos que permiten el tratamiento de patologías cada vez más complejas y reducir el tiempo de internación intrahospitalaria, como también las complicaciones relacionadas con el procedimiento.

    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.

    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

    To identify the best available evidence for the effect of toothbrushing on the initiation and progression of gingival recession and non-carious cervical lesions (NCCLs). A protocol was developed for the questions: Does traumatic toothbrushing, compared to normal toothbrushing, lead to an increased prevalence of non-inflammatory gingival recession? [FQ1] and NCCLs? [FQ2]. The search covered four electronic databases. Bibliographies of review articles, relevant texts, World and European Workshops were screened. Hand searches were performed of the Journals of Clinical Periodontology, Periodontology, Periodontal Research and IADR abstracts. A meta-analysis included 159 subjects and showed that subjects who used MTBs (manual toothbrush) had greater gingival recession after 12 months when compared with those using PTBs (powered toothbrush). Thirteen cross-sectional studies identified the most frequent toothbrushing factors associated with gingival recession as being toothbrushing frequency, a horizontal or scrub toothbrushing method, bristle hardness, toothbrushing duration and the frequency of changing a toothbrush. The principal toothbrushing factors associated with NCCLs were toothbrushing method and frequency. The data to support or refute the association between toothbrushing and gingival recession and NCCLs remain largely inconclusive. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available The objective of the study was to determine the dynamics of precancerous lesions in women of a cohort treated for cervical intraepithelial neoplasia (CIN and followed up over the next two years. The conditional probability of failure was calculated using the Kaplan-Meier method, and the raw and adjusted hazard ratios (HR were determined using Cox regression with a p-value entry of < 0.05. Of the 237 women who were treated, 51.5% were accompanied over 24 months, and treatment failed for 21.9% of those accompanied. Women who had five or more pregnancies (adjusted HR = 3.10, 95%CI: 1.28-7.51 or an initial histological diagnosis of CIN II/III demonstrated an independent risk of treatment failure (adjusted HR = 3.14, 95%CI: 1.20-8.19. Being in a stable relationship was a protective factor against treatment failure (adjusted HR = 0.47, 95%CI: 0.24-0.89. A history of more frequent pregnancies and a histological diagnosis of CIN II/III are directly correlated with risk of CIN treatment failure, whereas being in a stable relationship is inversely correlated with this risk.

    Human papillomavirus (HPV) inactivates the retinoblastoma 1 (RB1) gene by promoter methylation and reduces cellular E-cadherin expression by overexpression of DNA methyltransferase 1 (DNMT1). The Epstein-Barr virus (EBV) is an oncogenic virus that may be related to cervical carcinogenesis. In gastric cancer, it has been demonstrated that E-cadherin gene (CDH1) hypermethylation is associated with DNMT1 overexpression by EBV infection. Our aim was to analyze the gene promoter methylation frequency of RB1 and CDH1 and verify the association between that methylation frequency and HPV and EBV infection in cervical lesions. Sixty-five samples were obtained from cervical specimens: 15 normal cervices, 17 low-grade squamous intraepithelial lesions (LSIL), 15 high-grade squamous intraepithelial lesions (HSIL), and 18 cervical cancers. HPV and EBV DNA testing was performed by PCR, and the methylation status was verified by MSP. HPV frequency was associated with cervical cancer cases (p = 0.005) but not EBV frequency (p = 0.732). Viral co-infection showed a statistically significant correlation with cancer (p = 0.027). No viral infection was detected in 33.3% (5/15) of controls. RB1 methylated status was associated with cancer (p = 0.009) and HPV infection (p = 0.042). CDH1 methylation was not associated with cancer (p = 0.181). Controls and LSIL samples did not show simultaneous methylation, while both genes were methylated in 27.8% (5/18) of cancer samples. In the presence of EBV, CDH1 methylation was present in 27.8% (5/18) of cancer samples. Only cancer cases presented RB1 promoter methylation in the presence of HPV and EBV (33.3%). The methylation status of both genes increased with disease progression. With EBV, RB1 methylation was a tumor-associated event because only the cancer group presented methylated RB1 with HPV infection. HPV infection was shown to be significantly correlated with cancer conditions. The global methylation frequency was

    We retrospectively reviewed the pathologic changes and housfield unit of the low density lesion in solid mass on CT. Pathologically proved solid mass was evaluated in regard to the shape and margin of the low density in the mass on the CT scans of 23 patient. The CT number of the low density lesion was correlated with the pathologic changes. Pathologic changes of the low density lesions were; necrosis (n=17), hemorrhage (n=13), cyst (n=4), myxoid degeneration (n=2), hyaline degeneration (n=1), fibrosis (n=1), and mixed cellularity (n=1). In 14 cases, more than 2 pathologic changes were seen. In 11 cases, necrosis was associated with hemorrhage. The CT number ranged from 11.5 to 44.9 Housfield unit(HU) (mean, 25.2 HU). The average CT number was 26.9 HU in hemorrhage and necrosis, 17.2 HU in cystic change, 20.9 HU in myxoid degeneration, 35.7 HU in hyaline de generation, 22.3 HU in fibrosis, and 21.4 HU in mixed cellularity. The hemorrhage and necrosis in 17 cases showed irregular margin, amorphous shape, and showed centrifugal distribution. The cystic change in 4 cases showed well defined margin, round shape, and peripheral location in solid mass. The low density lesions in solid mass on CT represented variable pathologic changes; necrosis, hemorrhage, cyst, myxoid degeneration, hyaline degeneration, fibrosis, and mixed cellularity. Pathologic changes would not be differentiated on the basis of CT number

    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 lesions were

    2012-01-01

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

    2011-06-01

    Cervical cancer is an important cause of mortality among women in developing countries, especially in the Latin America and Caribbean (LAC) region. Infection with high-risk (HR) human papillomavirus (HPV) has been identified as the primary cause of cervical cancer. The aim of this study was to determine the frequency of HR-HPV genotypes in low-grade and high-grade squamous intraepithelial lesions (LSIL, HSIL) and cervical carcinoma (CC) among Venezuelan women. Subjects with histopathological diagnosis of LSIL, HSIL, and CC (LSIL=200; HSIL=100; CC=150) were enrolled in the study after obtaining informed consent. Biopsy samples of these subjects were analyzed to determine the lesion type. HPV detection and typing was done using polymerase chain reaction (PCR) and reverse hybridization. HPV type specific prevalence was determined in subjects with single and multiple infections. HPV DNA was detected in 68%, 95%, and 98.7% of LSIL, HSIL, and CC cases, respectively. HR-HPV and low-risk oncogenic HPV (LR-HPV) was observed in 66.9%/11.8% of LSIL cases, 87.3%/3.2% of HSIL cases, and 91.2%/0.7% of CC cases. HPV types -16/-18 (65%) were the most common high-risk HPV types observed, followed by types -52, -33, -45, and -31. Cervical cancer burden in Venezuelan women is substantial. HPV types -16/-18 were the most common types prevalent among Venezuelan women followed by types -52, -33, -45, and -31 (prevalence, ~90.1%). The results of this study provide baseline information on the HPV type distribution, which may facilitate the development of a cervical cancer prevention and control program in Venezuela.

    2013-09-01

    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.

  12. Stress Analysis of Occlusal Forces in Canine Teeth and Their Role in the Development of Non-Carious Cervical Lesions: Abfraction

    Shihab A. Romeed

    2012-01-01

    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.

    This study aimed to provide more information for cancer prevention strategies by determining the distribution of human papilloma virus (HPV) genotype prevalence in invasive cervical carcinoma (ICC) and precancerous lesion patients in the Yangtze River Delta area in China. This multi-centre descriptive cross-sectional study involves four university hospitals in the Jiangzhehu area. Women with histologically confirmed cervical intraepithelial neoplasia (CIN) 1, CIN2, CIN3 or ICC who were diagnosed and treated in the four selected hospitals between February 2012 and April 2014 were eligible for recruitment. The average age of the patients was 40.93 ± 11.87 years old, among whom the youngest was 17 years old and the oldest was 76 years old.Those with immunodeficiency diseases or a previous history of cancer or CIN were excluded. HPV genotyping was performed by a central laboratory. The distribution and age and disease specificity of the HPV genotype prevalence were analysed. Of the 2181 collected samples, 251 were ICC and 1930 were CIN. The mean age of cervical cancer and CIN patients was 40.93 ± 11.8 years (range, 17-76 years). The five most commonly identified HPV types in each lesion class were as follows: CIN1: 52, 58, 16, 33, and CP; CIN2: 16, 58, 52, 33, and 31; CIN3: 16, 58, 33, 52, and 31; and ICC: 16, 58, 18, 52, and 33. CIN1 had an earlier age of onset (30-40 years) than CIN2, CIN3, and cervical cancer. The age of onset of cervical cancer exhibited two peaks at 40-44 and 50-54 years of age. In all infected patients, the frequency of HPV infection with a single type was 62.9%, and with multiple types, it was 38.1%. There was no difference in the frequencies of multiple types amongst the different cervical lesions. The most prevalent genotypes in the investigated area (52, 58, 16 and 18) justify the necessity of anti-HPV vaccination in teenagers and young girls under 24 years old in the Yangtze River Delta area in China.

    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.

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. (author)

    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.

    Full Text Available Several causes are known to induce the right precordial ST elevation mimicking Brugada syndrome. Right ventricular outflow area is assumed to be responsible for such ECG changes. We experienced a case of anterior mediastinal infective mass lesion with a Brugada-like ECG. A 52-year-old female, who has pulmonary stenosis and recurrent episodes of right ventricular heart failure, complained of high fever, abdominal discomfort, and edema. On physical examination, jugular vein dilation, hepatomegaly, and facial and leg edema were noted. Leucocytosis was also noted on blood examination. An ECG showed right ventricular hypertrophy, incomplete right bundle branch block pattern and marked ST elevation on precordial leads mimicking Brugada syndrome. Magnetic resonance imaging revealed an abnormal mass shadow located on the anterior mediastinum and compressing the right ventricle (Figure 1A. Trans-thoracic echocardiography also showed the high echogenic mass lesion at the anterior side of right ventricle and the vicinity of pulmonary valve. After treatment with antibiotics, the mass lesion gradually shrunk. Concomitantly, the ST elevation disappeared with improvement of inflammatory markers (Figure 1B. The symptoms suggesting right ventricular failure were also ameliorated. The mechanism of Brugada-like ST elevation in this patient was considered to be compression, by the abnormal infective mass, of the right ventricular outflow tract with/without focal pericardial inflammation.

    2012-01-01

    Mammography is at present one of the available method for early detection of masses or abnormalities which is related to breast cancer.The calcifications. The challenge lies in early and accurate detection to overcome the development of breast cancer that affects more and more women throughout the world. Breast cancer is diagnosed at advanced stages with the help of the digital mammogram images. Masses appear in a mammogram as fine, granular clusters, which are often difficult to identify in a raw mammogram. The incidence of breast cancer in women has increased significantly in recent years. This paper proposes a computer aided diagnostic system for the extraction of features like mass lesions in mammograms for early detection of breast cancer. The proposed technique is based on a four-step procedure: (a) the preprocessing of the image is done, (b) regions of interest (ROI) specification, (c) supervised segmentation method includes two to stages performed using the minimum distance (M D) criterion, and (d) feature extraction based on Gray level Co-occurrence matrices GLC M for the identification of mass lesions. The method suggested for the detection of mass lesions from mammogram image segmentation and analysis was tested over several images taken from A L-llwiya Hospital in Baghdad, Iraq.The proposed technique shows better results.

    Lymphatic malformations in the neck can present as large fetal neck masses causing airway obstructions with potential perinatal demise and can pose a therapeutic challenge. We present a rare case of prenatally diagnosed large fetal neck mass with features of lymphatic malformation with intralesional hemorrhage of uncertain origin. Postnatal evaluation showed a complex cystic-solid lesion eroding through the skin with an open wound that made it clinically hard to differentiate from a teratoma. Given that malignancy could not be completely ruled out, surgery was favored. Final pathology showed a complex lymphatic malformation with intralesional hemorrhage, despite having no associated capillary, venous or arterial malformations.

    2016-01-01

    A Morel-Lavallée lesion, a type of soft tissue degloving injury that has also been referred to as a chronic expanding hematoma, is a relatively rare condition that usually develops following traumatic injury. Here, we present a case of a 60-year-old male with a Morel-Lavallée lesion diagnosed over 5 years after a traumatic injury of the hip. He presented with a large fungating mass and overlying skin ulceration, which was highly suspicious for sarcoma. However, lack of other systemic findings and constitutional complaints, as well as negative imaging studies, did not support a diagnosis of malignancy. This information, combined with the history of remote trauma to the affected area, instead led us to suspect the alternative diagnosis of a Morel-Lavallée lesion. The diagnosis was later confirmed by pathology showing a chronic expanding hematoma. To our knowledge, a Morel-Lavallée lesion presenting as a fungating mass has not been previously described.

  5. Triage of Women with Low-Grade Cervical Lesions - HPV mRNA Testing versus Repeat Cytology

    Sørbye, Sveinung Wergeland; Arbyn, Marc; Fismen, Silje; Gutteberg, Tore Jarl; Mortensen, Elin Synnøve

    2011-01-01

    Background In Norway, women with low-grade squamous intraepithelial lesions (LSIL) are followed up after six months in order to decide whether they should undergo further follow-up or be referred back to the screening interval of three years. A high specificity and positive predictive value (PPV) of the triage test is important to avoid unnecessary diagnostic and therapeutic procedures. Materials and Methods At the University Hospital of North Norway, repeat cytology and the HPV mRNA test PreTect HPV-Proofer, detecting E6/E7 mRNA from HPV types 16, 18, 31, 33 and 45, are used in triage of women with ASC-US and LSIL. In this study, women with LSIL cytology in the period 2005–2008 were included (n = 522). Two triage methods were evaluated in two separate groups: repeat cytology only (n = 225) and HPV mRNA testing in addition to repeat cytology (n = 297). Histologically confirmed cervical intraepithelial neoplasia of grade 2 or worse (CIN2+) was used as the study endpoint. Results Of 522 women with LSIL, 207 had biopsies and 125 of them had CIN2+. The sensitivity and specificity of repeat cytology (ASC-US or worse) were 85.7% (95% confidence interval (CI): 72.1, 92.2) and 54.4 % (95% CI: 46.9, 61.9), respectively. The sensitivity and specificity of the HPV mRNA test were 94.2% (95% CI: 88.7, 99.7) and 86.0% (95% CI: 81.5, 90.5), respectively. The PPV of repeat cytology was 38.4% (95% CI: 29.9, 46.9) compared to 67.0% (95% CI: 57.7, 76.4) of the HPV mRNA test. Conclusion HPV mRNA testing was more sensitive and specific than repeat cytology in triage of women with LSIL cytology. In addition, the HPV mRNA test showed higher PPV. These data indicate that the HPV mRNA test is a better triage test for women with LSIL than repeat cytology. PMID:21918682

    Hwang, H. S; Yun, M. J.; Lee, J. D

    2004-01-01

    Fluorodeoxyglucose positron emission tomography has been known to be useful in diagnosis and staging of malignancy. FDG PET has high sensitivity and easily detects malignant lesions that are missed and overlooked in anatomic imaging modality. We assessed the impact of FDG PET/CT compared to echocardiogram and enhanced CT scan. Five patients of intra- and pericardiac lesions were included in this study. All patients underwent PET/CT(GE Discovery ST), enhanced CT scan and echocardiogram. Two patients were non-small cell lung cancer, one of RV metastatic mass, the other of pericardial metastasis in RV region. One of melanoma with systemic metastases, had RA malignant masses. One of suspicious lung cancer and intracardiac mass, has proved to benign LA thrombosis. One of lymphoma showed suspicious cardiac mass, but revealed no abnormality in echocardiogram. FDG PET/CT is sensitive and useful method to detect intra- and pericardiac mass in patients with suspected malignancy. All patients except lymphoma were correctly diagnosed using FDG PET/ICT

  9. Age trends in the prevalence of cervical squamous intraepithelial lesions among HIV-positive women in Cameroon: a cross-sectional study

    Atashili, Julius

    2012-10-29

    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.

  10. Differentiating between endocervical glandular neoplasia and high grade squamous intraepithelial lesions in endocervical crypts: cytological features in ThinPrep and SurePath cervical cytology samples.

    Thiryayi, Sakinah A; Marshall, Janet; Rana, Durgesh N

    2009-05-01

    A recent audit at our institution revealed a higher number of cases diagnosed as endocervical glandular neoplasia on ThinPrep (TP) cervical cytology samples (9 cases) as opposed to SurePath (SP) (1 case), which on histology showed only high-grade cervical intraepithelial neoplasia (CIN) with endocervical crypt involvement (CI). We attempted to ascertain the reasons for this finding by reviewing the available slides of these cases, as well as slides of cases diagnosed as glandular neoplasia on cytology and histology; cases diagnosed as high-grade squamous intraepithelial lesions (HSIL) on cytology which had CIN with CI on histology and cases with mixed glandular and squamous abnormalities diagnosed both cytologically and histologically. Single neoplastic glandular cells and short pseudostratified strips were more prevalent in SP than TP with the cell clusters in glandular neoplasia 3-4 cells thick, in contrast to the dense crowded centre of cell groups in HSIL with CI. The cells at the periphery of groups can be misleading. Cases with HSIL and glandular neoplasia have a combination of the features of each entity in isolation. The diagnosis of glandular neoplasia remains challenging and conversion from conventional to liquid based cervical cytology requires a period of learning and adaptation, which can be facilitated by local audit and review of the cytology slides in cases with a cytology-histology mismatch.

    Full Text Available BACKGROUND Textile industry workers face so many health-related challenges compared to the general population. Lymphadenopathy is one of the most common presenting symptoms of these people. This study is done in inhabitants of Tiruppur, a major textile industry area in the state of Tamil Nadu, India, where people work in garment factories for low wages. The aim of the study is to- 1. Evaluate the usefulness of Fine Needle Aspiration Cytology (FNAC as a diagnostic tool in cases of cervical lymphadenopathy. 2. Analyse the various cytomorphological presentations of tuberculous lymphadenopathy. MATERIALS AND METHODS In this study, a spectrum of lesions was diagnosed by fine needle aspiration of lymph nodes of 56 patients presenting with cervical lymphadenopathy. The diseases were categorised into suppurative lymphadenitis, granulomatous lymphadenitis, metastatic tumour deposits and lymphoproliferative disorder. Various morphological presentations of tuberculous lymphadenitis were also analysed. RESULTS From this study, it is observed that the most common diagnosis of cervical lymphadenopathy is reactive lymphadenitis (34%, followed by granulomatous lymphadenitis (30%. Also, among the tuberculosis cases, it is found that majority of cases had only granulomas (45% followed by caseous necrosis with granulomas (28%. CONCLUSION Knowing the usefulness of FNAC, it is concluded that it is a valuable, noninvasive, reliable and cost-effective technique in such a high-risk population. It also helps the clinician to start treatment based on FNAC findings and do the necessary at the earliest.

    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.

    Patients who are ventilator dependent as a result of combined cervical spinal cord injury and phrenic nerve lesions are generally considered to be unsuitable candidates for diaphragmatic pacing due to loss of phrenic nerve integrity and denervation of the diaphragm. There is limited data regarding efficacy of simultaneous nerve transfers and diaphragmatic pacemakers in the treatment of this patient population. A retrospective review was conducted of 14 consecutive patients with combined lesions of the cervical spinal cord and phrenic nerves, and with complete ventilator dependence, who were treated with simultaneous microsurgical nerve transfer and implantation of diaphragmatic pacemakers. Parameters of interest included time to recovery of diaphragm electromyographic activity, average time pacing without the ventilator, and percent reduction in ventilator dependence. Recovery of diaphragm electromyographic activity was demonstrated in 13 of 14 (93%) patients. Eight of these 13 (62%) patients achieved sustainable periods (> 1 h/d) of ventilator weaning (mean = 10 h/d [n = 8]). Two patients recovered voluntary control of diaphragmatic activity and regained the capacity for spontaneous respiration. The one patient who did not exhibit diaphragmatic reinnervation remains within 12 months of initial treatment. Surgical intervention resulted in a 25% reduction (p nerve transfers and pacemaker implantation can result in reinnervation of the diaphragm and lead to successful ventilator weaning. Our favorable outcomes support consideration of this surgical method for appropriate patients who would otherwise have no alternative therapy to achieve sustained periods of ventilator independence.

    2012-11-01

    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.

    2008-02-01

    Non-carious cervical lesions (NCCLs) are often encountered in clinical practice and their aetiology attributed to toothbrush abrasion, erosion and tooth flexure. This paper aims to determine the prevalence and severity of NCCLs in a sample of patients attending a university clinic in Trinidad and to investigate the relationship with medical and dental histories, oral hygiene practices, dietary habits and occlusion. Data were collected via a questionnaire and clinical examination. Odds ratios were used to determine the association of the presence of lesions and the factors examined. One hundred and fifty-six patients with a mean age of 40.6 years were examined of whom 62.2% had one or more NCCLs. Forty five per cent of the lesions were sensitive to compressed air. Younger age groups had a significantly lower correlation with the presence of NCCLs than older age groups. Other significant factors included patients who reported heartburn, gastric reflux, headaches, bruxism, sensitive teeth and swimming or had a history of broken restorations in the last year. There was also significant correlation of NCCLs in patients who brushed more than once a day or used a medium or hard toothbrush. Patients with vegetarian diets and those who reported consuming citrus fruits, soft drinks, alcohol, yoghurt and vitamin C drinks were associated with the presence of lesions. Significant associations were also found in patients with group function, faceting, clicking joints or those who wore occlusal splints.

  17. Risk of progression of early cervical lesions is associated with integration and persistence of HPV-16 and expression of E6, Ki-67, and telomerase

    Full Text Available Background: Low-grade squamous intraepithelial lesions (LSIL are the earliest lesions of the uterine cervix, the persistence and integration of high-risk human papillomavirus (HR-HPV as type 16, which promotes the development of more aggressive lesions. Aim: To select more aggressive lesions with tendency to progress to invasive cervical cancer. Materials and Methods: A total of 75 cytological specimens in liquid base (Liqui-PREP were analyzed: 25 specimens were with no signs of SIL (NSIL and without HPV; 25 NSIL with HPV-16, and 25 with both LSIL and HPV-16. The expression of Ki-67, telomerase, and viral E6 was evaluated by immunocytochemistry; and the detection of viral DNA was done by polymerase chain reaction (PCR and restriction fragment length polymorphism (RFLPs for genotyping or sequencing of HPV-16. The physical state of HPV-16 was evaluated by in situ hybridization with amplification with tyramide. Results: Of the total group, 58.6% had LSIL associated with persistence and of these 59.3% was associated with integrated state of HPV as intense expression of E6, Ki-67 (P = 0.013, P = 0.055 has except for the expression of telomerase present a non-significant association (P<0.341. Conclusions: Overexpression of E6 and Ki-67 is associated with the integration of HPV-16, favoring viral persistence, and increasing the risk of progression in women with NSIL and LSIL.

  18. Is {sup 99m}Tc-MDP mammoscintigraphy useful in patients with breast mass lesions?

    1998-06-01

    Piccolo et al. advocated the usefulness of {sup 99m}Tc-MDP breast scan in differential diagnosis of breast mass with high accuracy. But there are little or no follow-up studies about it as we know. We studied {sup 99m}Tc-MDP uptake pattern and lesion/background ratio in patients complaining palpable breast lesions to evaluate the clinical usefulness of {sup 99m}Tc-MDP scan. Total 34 patients were studied with physical examination, mammogram and {sup 99m}Tc-MDP scan prospectively. Anteroposterior and both lateral view of breast were obtained 5 minutes after iv injection of 740 MBq {sup 99m}Tc-MDP. Breast uptake pattern of {sup 99m}Tc-MDP was analyzed by a grade system: 0=no uptake, grade 1=bilateral diffuse uptake, grade 2=asymmetric faint uptake, grade 3=focal hot uptake. 20 cases were pathologically confirmed by excision biopsy or aspiration biopsy. 14 cases were normal in physical examination and mammogram. Pathologic results showed 7 carcinomas, 6 benign solid tumors, and 7 fibrocystic changes. Grade 3 pattern of {sup 99m}Tc-MDP uptake was noted in 4/7 carcinomas, 3/5 benign solid tumors, and 1/7 fibrocystic changes. Grade 2 pattern was 2/7, 0/7, 3/7 respectively.

    Piccolo et al. advocated the usefulness of 99m Tc-MDP breast scan in differential diagnosis of breast mass with high accuracy. But there are little or no follow-up studies about it as we know. We studied 99m Tc-MDP uptake pattern and lesion/background ratio in patients complaining palpable breast lesions to evaluate the clinical usefulness of 99m Tc-MDP scan. Total 34 patients were studied with physical examination, mammogram and 99m Tc-MDP scan prospectively. Anteroposterior and both lateral view of breast were obtained 5 minutes after iv injection of 740 MBq 99m Tc-MDP. Breast uptake pattern of 99m Tc-MDP was analyzed by a grade system: 0=no uptake, grade 1=bilateral diffuse uptake, grade 2=asymmetric faint uptake, grade 3=focal hot uptake. 20 cases were pathologically confirmed by excision biopsy or aspiration biopsy. 14 cases were normal in physical examination and mammogram. Pathologic results showed 7 carcinomas, 6 benign solid tumors, and 7 fibrocystic changes. Grade 3 pattern of 99m Tc-MDP uptake was noted in 4/7 carcinomas, 3/5 benign solid tumors, and 1/7 fibrocystic changes. Grade 2 pattern was 2/7, 0/7, 3/7 respectively. The average L/B ratio was 1.66 in carcinomas, 1.68 in benign solid masses, 1.20 in fibrocystic diseases, 1.05 in normal patients. L/B ratio was higher in carcinoma and benign mass groups than in fibrocystic change and normal control groups(p=0.005). But there was no statistical difference between L/B ratio of malignant mass group and benign mass group. 99m Tc-MDP scan is not suitable to routine clinical use for breast mass diagnosis.

  20. Early Parenteral Nutrition in Patients with Biliopancreatic Mass Lesions, a Prospective, Randomized Intervention Trial.

    Janine Krüger

    Full Text Available Patients with biliopancreatic tumors frequently suffer from weight loss and cachexia. The in-hospital work-up to differentiate between benign and malignant biliopancreatic lesions requires repeated pre-interventional fasting periods that can aggravate this problem. We conducted a randomized intervention study to test whether routine in-hospital peripheral intravenous nutrition on fasting days (1000 ml/24 h, 700 kcal has a beneficial effect on body weight and body composition.168 patients were screened and 100 enrolled in the trial, all undergoing in-hospital work-up for biliopancreatic mass lesions and randomized to either intravenous nutrition or control. Primary endpoint was weight loss at time of hospital discharge; secondary endpoints were parameters determined by bioelectric impedance analysis and quality of life recorded by the EORTC questionnaire.Within three months prior to hospital admission patients had a median self-reported loss of 4.0 kg (25*th: -10.0 kg and 75*th* percentile: 0.0kg of body weight. On a multivariate analysis nutritional intervention increased body weight by 1.7 kg (95% CI: 0.204; 3.210, p = 0.027, particularly in patients with malignant lesions (2.7 kg (95% CI: 0.71; 4.76, p < 0.01.In a hospital setting, patients with suspected biliopancreatic mass lesions stabilized their body weight when receiving parenteral nutrition in fasting periods even when no total parenteral nutrition was required. Analysis showed that this effect was greatest in patients with malignant tumors. Further studies will be necessary to see whether patient outcome is affected as well.ClinicalTrials.gov NCT02670265.

    Our objective was to evaluate the progression and regression of cervical dysplasia in human immunodeficiency virus (HIV)-positive women during the late antiretroviral era. Risk factors as well as outcomes after treatment of cancerous or precancerous lesions were examined. This is a longitudinal retrospective review of cervical Pap tests performed on HIV-infected women with an intact cervix between 2004 and 2011. Subjects needed over two Pap tests for at least 2 years of follow-up. Progression was defined as those who developed a squamous intraepithelial lesion (SIL), atypical glandular cells (AGC), had low-grade SIL (LSIL) followed by atypical squamous cells-cannot exclude high-grade SIL (ASC-H) or high-grade SIL (HSIL), or cancer. Regression was defined as an initial SIL with two or more subsequent normal Pap tests. Persistence was defined as having an SIL without progression or regression. High-risk human papillomavirus (HPV) testing started in 2006 on atypical squamous cells of undetermined significance (ASCUS) Pap tests. AGC at enrollment were excluded from progression analysis. Of 1,445 screened, 383 patients had over two Pap tests for a 2-year period. Of those, 309 had an intact cervix. The median age was 40 years and CD4+ cell count was 277 cells/mL. Four had AGC at enrollment. A quarter had persistently normal Pap tests, 64 (31%) regressed, and 50 (24%) progressed. Four developed cancer. The only risk factor associated with progression was CD4 count. In those with treated lesions, 24 (59%) had negative Pap tests at the end of follow-up. More studies are needed to evaluate follow-up strategies of LSIL patients, potentially combined with HPV testing. Guidelines for HIV-seropositive women who are in care, have improved CD4, and have persistently negative Pap tests could likely lengthen the follow-up interval.

    1977-08-01

    A case of radionecrosis of the brain in a patient previously treated for squamous cell carcinoma of the scalp is presented. Cerebral angiography revealed a mass effect primarily in the right frontal area. Computed tomography showed extensive hemispheric edema. A frontal lobectomy was performed, and the recovery was excellent. The lower limit for brain tolerance for irradiation is about 5000 rads given in five weeks. This dose should not be exceeded when extracranial lesions are treated. Although computed tomography cannot diagnose brain necrosis, specifically, it should, along with the clinical history, be very helpful.

    Riboflavin deficiency can cause a variety of metabolic problems that lead to skin and mucosal disorders. Limited evidence suggests that high intake of riboflavin may reduce overall risks of cancer. However, association of this deficiency with cervical cancer and precancerous lesions are still not definitively known. In this study, we characterized the relationship between plasma and tissue riboflavin levels and C20orf54 protein expression in patients with cervical intraepithelial neoplasia (CIN) and cervical squamous cell carcinoma (CSCC) as well as the relationship of these levels with human papillomavirus virus 16, 18 (HPV16/18) infections. High-performance liquid chromatography (HPLC) was used to measure blood riboflavin levels in patients with CIN and CSCC, and an enzyme-linked immunosorbent assay (ELISA) was used to determine tissue riboflavin levels in patients with CSCC and matched normal mucous epithelia. The expression of C20orf54 in fresh CSCC and matched tissues were detected by qRT-PCR and western blot, respectively. And it was further confirmed by immunohistochemistry (IHC) with formalin-fixed, paraffin-embedded CIN and CSCC. An HPV genotyping chip was used to analyze HPV infection and typing. The results showed that patients with CIN and CSCC had decreased plasma riboflavin levels as compared with normal controls. There was also significantly decreased riboflavin in tissues from CSCC patients, when compared with normal cervical epithelia. C20orf54 expression were significantly up-regulated in CSCC compared to matched control on both mRNA and protein level. Tissue riboflavin levels were significantly lower in HPV16/18 positive tissue compared with HPV16/18-negative tissue, and an inverse association was found between tissue riboflavin levels and C20orf54 mRNA and protein expression in CSCC. Additionally, C20orf54 was significantly correlated with tumor stages. In conclusion, C20orf54 tend to play a protective role in Uyghur cervical carcinogenesis of

    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

    Full Text Available Primary pancreatic lymphoma is an unlikely malignancy accounting for less than 0.5% of pancreatic tumors. Clinical presentation is often nonspecific and may be clinically misdiagnosed as pancreatic adenocarcinoma. Here we present an Iranian case of primary pancreatic lymphoma in a 47-year-old male suffering from jaundice and 20% weight loss. Endoscopic ultrasound revealed a mixed echoic mass lesion at the head of pancreas. The patient underwent endoscopic ultrasound-guided fine needle aspiration of solid pancreatic mass and histopathologic diagnosis revealed granuloma. Computed tomography-guided core needle biopsy was performed and eventually histological examination showed granuloma that was coherent with the diagnosis of primary pancreatic lymphoma. Primary pancreatic lymphoma is a rare entity presenting with nonspecific symptoms, laboratory and radiological findings. Computed tomography results in combination with clinical and radiological studies generally provide guidance for appropriate investigation.

    2014-01-01

    Objective To determine the effect of supratentorial intraparenchymal mass lesions of various volumes on dural venous sinuses structure and transluminal pressures. Methods Three set of preparations were made using adult isolated head derived from fresh human cadaver. A supratentorial intraparenchymal balloon was introduced and inflated at various volumes and effect on dural venous sinuses was assessed by serial intravascular ultrasound, computed tomographic (CT), and magnetic resonance (MR) venograms. Contrast was injected through a catheter placed in sigmoid sinus for both CT and MR venograms. Serial trasluminal pressures were measured from middle part of superior sagittal sinus in another set of experiments. Results At intraparenchymal balloon inflation of 90 cm3, there was attenuation of contrast enhancement of superior sagittal sinus with compression visualized in posterior part of the sinus without any evidence of compression in the remaining sinus. At intraparenchymal balloon inflation of 180 and 210 cm3, there was compression and obliteration of superior sagittal sinus throughout the length of the sinus. In the coronal sections, at intraparenchymal balloon inflations of 90 and 120 cm3, compression and obliteration of the posterior part of superior sagittal sinus were visualized. In the axial images, basal veins were not visualized with intraparenchymal balloon inflation of 90 cm3 or greater although straight sinus was visualized at all levels of inflation. Trasluminal pressure in the middle part of superior sagittal sinus demonstrated a mild increase from 0 cm H2O to 0.4 cm H2O and 0.5 cm H2O with inflation of balloon to volume of 150 and 180 cm3, respectively. There was a rapid increase in transluminal pressure from 6.8 cm H2O to 25.6 cm H2O as the supratentorial mass lesion increased from 180 to 200 cm3. Conclusions Our experiments identified distortion and segmental and global obliteration of dural venous sinuses secondary to supratentorial mass lesion and

    2011-01-01

    Full Text Available Background: Various lateral mass screw fixation methods have been described in the literature with various levels of safety in relation to the anterior neurovascular structures. This study was designed to radiologically determine the minimum lateral angulations of the screw to avoid penetration of the vertebral artery canalusing three of the most common techniques: Roy-Camille, An, and Magerl. Materials and Methods: Sixty normal cervical CT scans were reviewed. A minimum lateral angulation of a 3.5 mm lateral mass screw which was required to avoid penetration of the vertebral artery canal at each level of vertebra were measured. Results: The mean lateral angulations of the lateral mass screws (with 95% confidence interval to avoid vertebral artery canal penetration, in relation to the starting point at the midpoint (Roy-Camille, 1 mm medial (An, and 2 mm medial (Magerl to the midpoint of lateral mass were 6.8° (range, 6.3-7.4°, 10.3° (range, 9.8-10.8°, and 14.1° (range, 13.6-14.6° at C3 vertebrae; 6.8° (range, 6.2-7.5°, 10.7° (range, 10.0-11.5°, and 14.1° (range, 13.4-14.8° at C4 vertebrae; 6.6° (range, 6.0-7.2°, 10.1° (range, 9.3-10.8°, and 13.5° (range, 12.8-14.3° at C5 vertebrae and 7.6° (range, 6.9-8.3°, 10.9° (range, 10.3-11.6°, and 14.3° (range, 13.7-15.0° at C6 vertebrae. The recommended lateral angulations for Roy-Camille, Magerl, and An are 10°, 25°,and 30°, respectively. Statistically, there is a higher risk of vertebral foramen violation with the Roy-Camille technique at C3, C4 and C6 levels, P < 0.05. Conclusions: Magerl and An techniques have a wide margin of safety. Caution should be practised with Roy-Camille′s technique at C3, C4, and C6 levels to avoid vertebral vessels injury in Asian population.

    The clinically validated high-risk human papillomavirus (hrHPV) Hybrid Capture 2 (HC2) and GP5+/6+-PCR assays were analyzed on an Indicating FTA Elute cartridge (FTA cartridge). The FTA cartridge is a solid dry carrier that allows safe transport of cervical samples. FTA cartridge samples were compared with liquid-based samples for hrHPV and high-grade cervical intraepithelial neoplasia (CIN) detection. One cervical sample was collected in a liquid-based medium, and one was applied to the FTA cartridge. DNA was eluted directly from the FTA cartridge by a simple elution step. HC2 and GP5+/6+-PCR assays were performed on both the liquid-based and the FTA-eluted DNA of 88 women. Overall agreement between FTA and liquid-based samples for the presence of hrHPV was 90.9% with GP5+/6+-PCR and 77.3% with HC2. The sensitivity for high-grade CIN of hrHPV testing on the FTA cartridges was 84.6% with GP5+/6+-PCR and only 53.8% with HC2. By comparison, these sensitivities on liquid-based samples were 92.3% and 100% for GP5+/6+-PCR and HC2, respectively. Therefore, the FTA cartridge shows reasonably good overall agreement for hrHPV detection with liquid-based media when using GP5+/6+-PCR but not HC2 testing. Even with GP5+/6+-PCR, the FTA cartridge is not yet capable of detecting all high-grade CIN lesions.

    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.

    To assess the diagnostic value of cervical cytology and HPV HR DNA testing for the diagnosis of low grade and high-grade squamous intraepithelial lesions across different age groups. The study included 1103 patients, age 25-70 years. All patients underwent in-depth diagnostic tests following either an abnormal Pap test result or a clinically suspicious cervical lesion. In all women the following examinations were performed: a molecular test detecting 14 high-risk types of HPV, a colposcopy examination, as well as directed-biopsy of the cervix. The studied population was subdivided into four age groups. It was observed that the percentage of high grade squamous intraepithelial lesions (HSIL) and cancers increased with women's age. Sensitivity of both methods for detecting high-grade squamous intraepithelial lesions was highest for women aged 40-49 years. Sensitivity values of HPV testing was higher than that of cervical cytology among women under age 50. Specificity of HPV testing increased significantly with age of women and was several fold higher across all age groups than the specificity of cervical cytology.

    2002-01-01

    Aim: This prospective study is to compare the results of primary (recurrence) and metastatic lesions detection, based on pathologic results, with computed tomography (CT) and/or magnetic resonance imaging (MRI) and positron emission tomography (PET) with [18F]-fluoro-2-deoxy-D-glucose (FDG) in invasive cervical cancer (ICC). Materials and Methods: An FDG PET scan was performed in 136 patients with ICC (107 squamous cell carcinoma [SCC], 18 adenocarcinoma [AdenoCa], 5 adeosquamous cell carcinoma, 4 small cell carcinoma, and 2 poorly differentiated carcinoma; from FIGO staging IB to IVB prior to operation). CT and/or MRI image were performed within one week before or after FDG PET scan was done. The accuracy of lymph node status was based on histological result or a second FDG PET combined with a CT and/or MRI image images. Results: Totally, 68 main tumor and 147 metastatic lesions were recognized by either histopathology or a follow up study. On a lesion basis, CT and/or MRI image images demonstrated 63 (92.6 %) main tumor and 103 (70.1 %) metastatic lesions. For lymph node metastatic lesions detection, there were 6(75 %) enlarged inguinal lymph nodes, 38(76 %) enlarged pelvic lymph nodes (PLN), 28(73.7 %) enlarged para-aortic lymph nodes (PAN), 8(50 %) enlarged supraclavicular lymph nodes (SLNs), and 5(62.5 %) enlarged mediastinal lymph nodes (MLNs). Liver metastases were found in 4(100 %), in lung in 7(70 %) and in bone in 5(83.3 %). Peritoneal metastases were found in 2(28.6 %). FDG PET demonstrated 63 (92.6 %) and 135 (91.8 %) metastatic lesions. For lymph node metastases, FDG PET found 8(100 %) enlarged inguinal lymph nodes, 44(88 %) enlarged PLNs, 36(94.7 %) enlarged PANs, 15(93.8 %) enlarged SLNs, and 8(100 %) enlarged MLNs. Liver metastases were found in 4(100 %), in lung in 9(90 %) and in bone in 6(100 %). Peritoneal metastases were found in 5(71.4 %). On a patient basis, with FDG PET scan, 31(22.8%) were upstaging while 4(2.9%) were down staging. 35

    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 cervical cancer

  15. Loss of Dependence on Continued Expression of the Human Papillomavirus 16 E7 Oncogene in Cervical Cancers and Precancerous Lesions Arising in Fanconi Anemia Pathway-Deficient Mice

    Soyeong Park

    2016-05-01

    Full Text Available Fanconi anemia (FA is a rare genetic disorder caused by defects in DNA damage repair. FA patients often develop squamous cell carcinoma (SCC at sites where high-risk human papillomaviruses (HPVs are known to cause cancer, including the cervix. However, SCCs found in human FA patients are often HPV negative, even though the majority of female FA patients with anogenital cancers had preexisting HPV-positive dysplasia. We hypothesize that HPVs contribute to the development of SCCs in FA patients but that the continued expression of HPV oncogenes is not required for the maintenance of the cancer state because FA deficiency leads to an accumulation of mutations in cellular genes that render the cancer no longer dependent upon viral oncogenes. We tested this hypothesis, making use of Bi-L E7 transgenic mice in which we temporally controlled expression of HPV16 E7, the dominant viral oncogene in HPV-associated cancers. As seen before, the persistence of cervical neoplastic disease was highly dependent upon the continued expression of HPV16 E7 in FA-sufficient mice. However, in mice with FA deficiency, cervical cancers persisted in a large fraction of the mice after HPV16 E7 expression was turned off, indicating that these cancers had escaped from their dependency on E7. Furthermore, the severity of precancerous lesions also failed to be reduced significantly in the mice with FA deficiency upon turning off expression of E7. These findings confirm our hypothesis and may explain the fact that, while FA patients have a high frequency of infections by HPVs and HPV-induced precancerous lesions, the cancers are frequently HPV negative.

    The aim of the present study was to gather information regarding the molecular epidemiology of Human papillomavirus (HPV) and related risk factors in a group of women with low- and high-grade cervical lesions and cancer from the coastal region of Ecuador. In addition, we studied the evolution of HPV variants from the most prevalent types and provided a temporal framework for their emergence, which may help to trace the source of dissemination within the region. We analyzed 166 samples, including 57 CIN1, 95 CIN2/3 and 14 cancer cases. HPV detection and typing was done by PCR-sequencing (MY09/MY11). HPV variants and estimation of the time to most recent common ancestor (tMRCA) was assessed through phylogeny and coalescence analysis. HPV DNA was found in 54.4% of CIN1, 74.7% of CIN2/3 and 78.6% of cancer samples. HPV16 (38.9%) and HPV58 (19.5%) were the most prevalent types. Risk factors for the development of cervical lesions/cancer were the following: three or more pregnancies (OR=4.3), HPV infection (OR=3.7 for high-risk types; OR=3.5 for HPV16), among others. With regard to HPV evolution, HPV16 isolates belonged to lineages A (69%) and D (31%) whereas HPV58 isolates belonged only to lineage A. The period of emergence of HPV16 was in association with human populations (tMRCA=91052 years for HPV16A and 27000 years for HPV16D), whereas HPV58A preceded Homo sapiens evolution (322257 years). This study provides novel data on HPV epidemiology and evolution in Ecuador, which will be fundamental in the vaccine era. Copyright © 2017 Asociación Argentina de Microbiología.

    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

  19. Loss of Dependence on Continued Expression of the Human Papillomavirus 16 E7 Oncogene in Cervical Cancers and Precancerous Lesions Arising in Fanconi Anemia Pathway-Deficient Mice

    Park, Soyeong; Park, Jung Wook; Pitot, Henry C.

    2016-01-01

    ABSTRACT   Fanconi anemia (FA) is a rare genetic disorder caused by defects in DNA damage repair. FA patients often develop squamous cell carcinoma (SCC) at sites where high-risk human papillomaviruses (HPVs) are known to cause cancer, including the cervix. However, SCCs found in human FA patients are often HPV negative, even though the majority of female FA patients with anogenital cancers had preexisting HPV-positive dysplasia. We hypothesize that HPVs contribute to the development of SCCs in FA patients but that the continued expression of HPV oncogenes is not required for the maintenance of the cancer state because FA deficiency leads to an accumulation of mutations in cellular genes that render the cancer no longer dependent upon viral oncogenes. We tested this hypothesis, making use of Bi-L E7 transgenic mice in which we temporally controlled expression of HPV16 E7, the dominant viral oncogene in HPV-associated cancers. As seen before, the persistence of cervical neoplastic disease was highly dependent upon the continued expression of HPV16 E7 in FA-sufficient mice. However, in mice with FA deficiency, cervical cancers persisted in a large fraction of the mice after HPV16 E7 expression was turned off, indicating that these cancers had escaped from their dependency on E7. Furthermore, the severity of precancerous lesions also failed to be reduced significantly in the mice with FA deficiency upon turning off expression of E7. These findings confirm our hypothesis and may explain the fact that, while FA patients have a high frequency of infections by HPVs and HPV-induced precancerous lesions, the cancers are frequently HPV negative. Importance   Fanconi anemia (FA) patients are at high risk for developing squamous cell carcinoma (SCC) at sites where high-risk human papillomaviruses (HPVs) frequently cause cancer. Yet these SCCs are often HPV negative. FA patients have a genetic defect in their capacity to repair damaged DNA. HPV oncogenes cause an

  20. Enhancing Mass Lesion of the Sphenoid: Atypical Presentation of Ongoing Pneumatization

    2016-01-01

    Full Text Available Sinus pneumatization is a complex variable process that begins in early life and continues for many years. We present a case of a 6-year-old boy with progressive headaches and neurologic symptoms suggestive of intracranial pathology. The presence of enhancing tissue within the sphenoid sinus created a diagnostic dilemma which leads to a transsphenoidal biopsy. Knowledge of imaging characteristics associated with incomplete pneumatization can help differentiate it from more ominous skull base pathology and prevent unnecessary testing. We describe four-year imaging follow-up in a patient with incomplete pneumatization of the sphenoid sinus presenting as an enhancing mass lesion with subsequent follow-up imaging demonstrating gradual regression and increased aeration of the sphenoid sinus.

  1. Apparent Diffusion Coefficient Maps of Pediatric Mass Lesions with Free-Breathing Diffusion-Weighted Magnetic Resonance: Feasibility Study

    Olsen, Oe.E.; Sebire, N.J.

    2006-01-01

    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 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.

    Crystal-storing histiocytosis (CSH) is an uncommon finding in lymphoplasmacytic disorders that presents histiocytes with abnormal intralysosomal accumulations of immunoglobulin light chains as crystals of unknown etiology. A 38-year-old woman with antiphospholipid syndrome had a surgical lung biopsy because of multiple lung mass lesions. In a right middle lobe lesion, lymphoplasmacytic cells had a monocytoid appearance, destructive lymphoepithelial lesions, and positive immunoglobulin heavy chain (IGH) gene rearrangements. A right upper lobe lesion manifested proliferating rounded histiocytes with abundant, deeply eosinophilic cytoplasm and negative IGH gene rearrangements. Electron microscopy and mass spectrometry revealed a case of pulmonary CSH: abnormal proliferation of the immunoglobulin κ chain of a variable region that may be crystallized within plasma cells and histiocytes. We report a rare case of localized pulmonary CSH complicating pulmonary mucosa-associated lymphoid tissue lymphoma with multiple mass lesions. We demonstrate advances in the understanding of the pathogenesis of CSH by various analyses of these lesions. Copyright © 2017 Elsevier Inc. All rights reserved.

    Apuzzo, M.L.; Sabshin, J.K.

    1983-01-01

    A prototype Brown-Roberts-Welles stereotactic instrument has been used as both a diagnostic and a therapeutic surgical adjunct in cases of intracranial mass lesions. Eighty-three procedures (142 point placements) required computerized guidance stereotaxy. The unit accomplished point intracranial access with an accuracy of greater than 1 mm. Pathological processes included a variety of neoplasms (56 cases), strokes (7 cases), and infections (20 cases) affecting deep regions of the cerebral hemispheres, the ventricular system, the cerebellum, and the rostral brain stem. Procedures were undertaken with the patient under local anesthesia for biopsy (300 point specimens), culture, evacuation, aspiration, endoscopic excision, and implantation of radioisotopes. The techniques and instrumentation for each of these procedures are described. Procedural objectives were satisfactorily accomplished with no mortality and an overall complication rate of 4%. Recovery of tissue specific to establish a histological diagnosis or the etiological factors related to each disease process was realized in 94% of the cases. These results were obtained with scanner utilization times averaging 15 minutes and procedurally related patient recovery periods of less than 4 hours. The value and adaptability of the instrumentation and techniques are illustrated, and potential future applications are discussed

    2014-01-01

    Full Text Available Objectives. The aims of this study were to compare the characteristics of women who got a Pap-test during the mass media campaign, carried out in an Italian region by broadcasts advertising, and two years later and to identify the determinants of knowledge of cervical cancer etiology and of the adherence to the mass media campaign. Methods. A cross-sectional survey was carried out through a self-administered questionnaire. Results. A total of 8570 randomly selected women were surveyed, 823 of these had a Pap-test during the mass media campaign period and 7747 two years later. Higher educational level, being not married, and living in urban areas were the main independent characteristics associated with a higher level of knowledge of cervical cancer etiology, although a previous treatment following a Pap smear abnormality was the strongest predictor (OR = 2.88; 95% CI: 2.43–3.41. During the campaign period women had the Pap-test more frequently as a consequence of the mass media campaign (OR = 8.28; 95% CI; 5.51–12.45. Conclusions. Mass media campaign is a useful tool to foster cervical screening compliance; however, its short-term effect suggests repeating it regularly.

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

    2015-01-01

    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

  11. Age-specific prevalence of HPV genotypes in cervical cytology samples with equivocal or low-grade lesions

    Brismar-Wendel, S; Froberg, M; Hjerpe, A; Andersson, S; Johansson, B

    2009-01-01

    Background: To define the spectrum of human papillomavirus (HPV) types and establish an age limit for triage HPV testing in atypical squamous cells of undetermined significance (ASCUS) and low-grade squamous intraepithelial lesion (LSIL). Materials and methods: 343 liquid-based cytological samples from the population-based screening programme with minor abnormalities were subjected to HPV genotyping (Linear Array, Roche, Basel, Switzerland). Results: High-risk human papillomavirus (HR-HPV) was found in 71% of LSIL and 49% of ASCUS cases (Page-dependent in LSIL (P=0.01), with decreasing prevalence until the age of 50 years, followed by a slight increase. Human papillomavirus type 16 was the most common HR-HPV, found in 23% of HPV-positive women. Human papillomavirus type 18 was the sixth most common, found in 9.9% (Page-dependent quadratic trend was observed for multiple infections (P=0.01) with a trough at about 42 years. The most common HR-HPV types to show a coinfection with HPV16 (clade 9) were HPV39 (28%), 45 (38%), and 59 (46%), belonging to HPV18 clade 7. The frequency of low-risk (LR) vs probable HR and HR-HPV also followed an age-dependent quadratic trend. Conclusions: After the age of 25 years, HR-HPV prevalence is similar in LSIL and ASCUS cases, motivating a low age limit for triage HPV testing. Multiple infections and LR/HR-HPV dominance are age-dependent. Genotyping in longitudinal design is needed to elucidate the importance of multiple infections in cancer progression and in cross-protection from vaccination. PMID:19623178

Conclusions: The discussed technique is safe and provides a strong fixation and a ground for ultimate arthrodesis.

  14. Colposcopic triage methods for detecting cervical intraepithelial neoplasia grade 3 after cytopathological diagnosis of low-grade squamous intraepithelial lesion: a systematic review on diagnostic tests

    Flávia de Miranda Corrêa

    Full Text Available CONTEXT AND OBJECTIVE: The age-stratified performance of the oncogenic HPV-DNA (human papillomavirus deoxyribonucleic acid test for triage of low-grade squamous intraepithelial lesions (LSIL requires investigation. The objective of this study was to evaluate and compare the age-stratified performance (cutoff point: 35 years of oncogenic HPV-DNA testing and repeated cytological tests, for detecting cervical intraepithelial neoplasia grade 3 (CIN3, in order to triage for LSIL. DESIGN AND SETTING: Systematic review. Studies were identified in nine electronic databases and in the reference lists of the articles retrieved. METHODS: The eligibility criteria consisted of initial cytological findings of LSIL; subsequent oncogenic HPV-DNA testing and repeated cytological tests; and CIN3 detection. The Quality Assessment of Diagnostic Accuracy Studies (QUADAS guidelines were used for quality assessment. Qualitative information synthesis was performed. RESULTS: Out of 7,776 studies, 284 were identified as pertinent and three fulfilled the eligibility criteria. The CIN3 prevalence ranged from 6% to 12%. The HPV-DNA positivity rate ranged from 64% to 83%; sensitivity for CIN3 detection ranged from 95.2% to 100%; and specificity was available in two studies (27% and 52%. The sensitivity of repeated cytological tests, in relation to the threshold for atypical squamous cells of undetermined significance (ASCUS, was available in two studies (33% and 90.8%; and specificity was available in one study (53%. CONCLUSIONS: Currently, there is no scientific evidence available that would prove that colposcopic triage using oncogenic HPV-DNA testing to detect CIN3 performs better than repeated cytological tests, among women with LSIL aged 35 years and over.

    2000-01-01

    Objective: To probe into the technique and diagnostic value of MR virtual colonoscopy (MRVC) compared with CT virtual colonoscopy (CTVC) and colonoscopy. Methods: Two approximately 25-cm-long-sections of fresh pit colon in vitro had 20 mass lesions created ranging from 3 mm to 12 mm in diameter. MR scanning, as well as CT scanning of the water- or air-insufflated colon was performed, and CT data were obtained with collimation of 3 mm at a pitch of 1.0 and reconstruction intervals of 1.5 mm. MRI data were acquired with the same matrix and reformatting slab, and with heavily T 2 -weighted fast spin-echo pulse sequences. Post processed image sets were performed by the same experienced doctor on a workstation using navigator software based on CT or MRI source imaging data. One section was also underwent electron colonoscopy. Results: MRVC and CTVC displayed colon morphology in a manner similar to colonoscopy. The sensitivity of MRVC and CTVC were all 100%, and the accuracy was 71.4% for MRVC and 100% for CTVC. With the combined analysis of the four-in-one multi-view images, they accurately demonstrated the site and size of lesions and distinguished the lesions from the artifacts such as small air bubbles, and the accuracy of MRVC was improved up to 100%. CTVC was better than MRVC (P<0.05), but both were inferior to colonoscopy in depicting mucosal details of the colon and lesions (P < 0.025). Conclusion: Virtual colonoscopy (CTVC or MRVC, the former appears better) provided noninvasive endoscope-like display of the colon, and permitted identification of colonic mass lesions as small as 3 mm in diameter, the diagnostic accuracy could be improved by combining with source images and other reformations

    Trichomonas vaginitis (TV) infection has obviously been implicated in gynecological morbidity but still unclear in cervical lesions. To evaluate the risk of hr-HPV infection and cervical intraepithelial neoplasia grade 2 or worse (CIN2 + ) by TV infection. The pooled study was conducted among 12 population-based, cervical cancer screening studies throughout China (N = 24,054). HPV was detected by Hybrid Capture ® 2 (HC2) test. Past TV infection was measured by self-reporting, current TV infection was diagnosed by liquid-based cytology (LBC), cervical lesions was diagnosed by histopathology. Respective prevalence of hr-HPV and CIN2+ were 17.4% and 3.3%. Out of 24,054 women, 14.6% reported past TV infection, and out of 11,853 women, 9.9% had current TV infection. Current TV-positive women had an increased risk for hr-HPV (OR 1.31, 95%CI: 1.11-1.56). The risk of CIN2+ decreased for hr-HPV positive women with current TV infection (adjusted OR 0.50, 95% CI: 0.30-0.84) and past TV infection (adjusted OR 0.68, 95% CI: 0.54-0.86). Among hr-HPV negative women, no significant associations were observed between past or current TV infection and risk of CIN2+. Women infected with HPV are more likely to be infected by other types of sexually transmitted diseases. Current TV-positive women had an increased risk for hr-HPV infection compared to currently TV-negative women. Both past and current TV-positive women had a decreased risk for CIN2+, especially among high-risk HPV positive women. More direct investigation into the interaction between TV, HPV, inflammatory signals, and risk of carcinogenesis are further needed. Copyright © 2017. Published by Elsevier B.V.

    Objectives: To assess the value of T/NT in FDG imaging with a coincidence camera for diagnosis of pulmonary nodules and mass lesions. Methods: 18F-FDG imaging were performed in 57 patients with a mean age of 62.18 (range from 33 83 years old) for diagnosis of pulmonary nodules and mass lesions using a gamma camera with 1 inch crystal in coincidence mode (Siemens E.comduet). 175 296 MBq (5 8 mci) of 18F-FDG was given by iv on an empty stomach at least for 6 hours, and a whole body imaging without brain and legs was performed after 40 60 minutes. The count rate of target ROI and no-target ROI (T/NT) were calculated as a semiquantative analysis to differentiate malignant from inflammatory lesions. The result was compared with CT, MRI, and/or pathology. Results: The mean value of T/NT in malignant lesions (N=45) in lungs is 4.32 (range 1.61 10.62). But it is 1.52 (range 1.37 1.95) in inflammatory lesions (N=17) in lungs, and 4.09 (range 2.2 7.01) in lung tuberculosis lesions (N=5). In 45 malignant, the value of T/NT is less than 2.0 in only 3 lesions. So the overlapping of T/NT value is very little between malignant and inflammatory lesions. But there is full overlapping of T/NT value between malignant and tuberculosis lesions. Conclusions: Focal pulmonary nodules and mass lesions are commonly encountered in clinical practice, and PET with 18F-FDG has proved to be an accurate noninvasive test for identifying pulmonary malignant lesions. The technique of semiquantity with T/NT is useful to differentiate malignant from inflammatory lesions. But it is invalidate for distinguishing malignant from tuberculosis lesions. (authors)

    Little is known about the characteristics of high-risk papillomavirus (HR-HPV) infection in men. The aims of this cross-sectional study were: (a) to investigate HR-HPV prevalence and genotype distribution in men, sexual partners of women presenting with high-grade cervical intraepithelial neoplasia (HG-CIN), according to epidemiological characteristics, and (b) to assess type-specific concordance between partners. A total of 125 men were recruited within the first 6 months after HG-CIN diagnosis of their partner. Samples from the coronal sulcus, glans penis shaft, and scrotum were tested with linear array HPV genotyping assay (Roche Diagnostics, Mannheim, Germany). Type-specific concordance within 120 couples was studied. Epidemiological factors were evaluated by multivariate logistic regression analysis. SPSS 19 (IBM, Chicago, USA). The prevalence of HR-HPV infection in males was 50.4% (63/125). HPV16/53/52/51/66/31 were the most frequent genotypes (24/10.4/9.6/8.8/8/7.2%, respectively). Current smoking was associated with an increased risk for HR-HPV infection in men (38.2% (21/55) vs 60% (42/70), OR 2.4, p=0.025). Among 60 infected couples, 62% shared at least one genotype: 41.7% couples were concordantly HPV16 positive and 18.3% were HPV16 negative (kappa value: 0.21). The proportion of women with the same genotype as their male partner was higher than the proportion of men sharing the same genotype as their female partner: 58.7% (37/63) vs 30.8% (37/120), p<0.0001. Sexual partners of women with HG-CIN are a significant reservoir and vector of HPV infection, a fact that could contribute to making viral clearance more difficult to achieve in their partners after treatment of their HG-CIN lesions.

    Women persistently infected with human papillomavirus (HPV) type 16 are at high risk for development of cervical intraepithelial neoplasia grade 3 or cervical cancer (CIN3+). We aimed to identify biomarkers for progression to CIN3+ in women with persistent HPV16 infection. In this prospective study......, 11,088 women aged 20-29 years were enrolled during 1991-1993, and re-invited for a second visit two years later. Cervical cytology samples obtained at both visits were tested for HPV DNA by Hybrid Capture 2 (HC2), and HC2-positive samples were genotyped by INNO-LiPA. The cohort was followed for up...... to 19 years via a national pathology register. To identify markers for progression to CIN3+, we performed microarray analysis on RNA extracted from cervical swabs of 30 women with persistent HPV16-infection and 11 HPV-negative women. Six genes were selected and validated by quantitative PCR. Three genes...

  4. Automated analysis of non-mass-enhancing lesions in breast MRI based on morphological, kinetic, and spatio-temporal moments and joint segmentation-motion compensation technique

    2013-12-01

    Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) represents an established method for the detection and diagnosis of breast lesions. While mass-like enhancing lesions can be easily categorized according to the Breast Imaging Reporting and Data System (BI-RADS) MRI lexicon, a majority of diagnostically challenging lesions, the so called non-mass-like enhancing lesions, remain both qualitatively as well as quantitatively difficult to analyze. Thus, the evaluation of kinetic and/or morphological characteristics of non-masses represents a challenging task for an automated analysis and is of crucial importance for advancing current computer-aided diagnosis (CAD) systems. Compared to the well-characterized mass-enhancing lesions, non-masses have no well-defined and blurred tumor borders and a kinetic behavior that is not easily generalizable and thus discriminative for malignant and benign non-masses. To overcome these difficulties and pave the way for novel CAD systems for non-masses, we will evaluate several kinetic and morphological descriptors separately and a novel technique, the Zernike velocity moments, to capture the joint spatio-temporal behavior of these lesions, and additionally consider the impact of non-rigid motion compensation on a correct diagnosis.

    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

    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

  7. Reduction in the copy number and expression level of the recurrent human papillomavirus integration gene fragile histidine triad (FHIT predicts the transition of cervical lesions.

    Liming Wang

    Full Text Available Cervical cancer is the second most common cancer and the third leading cause of cancer death in females worldwide, especially in developing countries. High risk human papillomavirus (HR-HPV infection causes cervical cancer and precancerous cervical intraepithelial neoplasia (CIN. Integration of the HR-HPV genome into the host chromatin is an important step in cervical carcinogenesis. The detection of integrated papillomavirus sequences-PCR (DIPS-PCR allowed us to explore HPV integration in the human genome and to determine the pattern of this integration. We performed DIPS-PCR for 4 cell lines including 3 cervical cancer cell lines and 40 tissue samples. Overall, 32 HR-HPV integration loci were detected in the clinical samples and the HeLa and SiHa cell lines. Among all the integration loci, we identified three recurrent integration loci: 3p14.2 (3 samples, 13q22.1 (2 samples and a SiHa cell line and 8q24 (1 sample and a HeLa cell line. To further explore the effect of HR-HPV integration in the 3p14.2 locus, we used fluorescence in situ hybridization (FISH to determine the copy number of the 3p14.2 locus and immunohistochemistry (IHC to determine the protein expression levels of the related FHIT gene in the clinical samples. Both the 3p14.2 locus copy number and FHIT protein expression levels showed significant decreases when CIN transitioned to cervical cancer. HPV copy number was also evaluated in these clinical samples, and the copy number of HPV increased significantly between CIN and cervical cancer samples. Finally, we employed receiver operating characteristic curve (ROC curve analysis to evaluate the potential of all these indexes in distinguishing CIN and cervical cancer, and the HPV copy number, FHIT copy number and FHIT protein expression levels have good diagnostic efficiencies.

    North American paragonimiasis is well described in omnivorous and carnivorous animals on this continent. Humans are rarely infected, largely because of dietary customs, but are at risk for infection if raw or undercooked crayfish are consumed. We describe a patient with a pleuropulmonary infection due to Paragonimus kellicotti that presented as recurrent pneumothoraces and a cavitary lesion. This is the first case of North American paragonimiasis in which the diagnosis was based on the morphology of the eggs present in histologic sections.

  9. Phase sensitive reconstruction of T1-weighted inversion recovery in the evaluation of the cervical cord lesions in multiple Sclerosis; is it similarly eligible in 1.5 T magnet fields?

    Shayganfar, A; Sarrami, A H; Fathi, S; Shaygannejad, V; Shamsian, S

    2018-04-22

    In primary studies with 3 T Magnets, phase sensitive reconstruction of T1-weighted inversion recovery (PSIR) have showed ability to depict the cervical multiple sclerosis (MS) lesions some of which may not be detected by short tau inversion recovery (STIR). Regarding to more availability of 1.5 T MRI, this study was designed to evaluate the eligibility of PSIR in 1.5 T for detection of spinal cord MS lesions. In a study between September 2016 till March 2017 the patients with proven diagnosis of MS enrolled to the study. The standard protocol (sagittal STIR and T2W FSE and axial T2W FSE) as well as sagittal PSIR sequences were performed using a 1.5 T magnet. The images were studied and the lesions were localized and recorded as sharp or faint on each sequence. Of 25 patients (22 females and 3 males, with mean age of 33.5 ± 9.8 years and mean disease duration of 5.4 ± 3.9 years) 69 lesions in STIR, 53 lesions in T2W FSE, 47 lesions in Magnitude reconstruction of PSIR (Magnitude), and 30 lesions in phase sensitive (real) reconstruction PSIR were detected. A Wilcoxon signed-rank test showed STIR has a statistically significant higher detection rate of the plaques rather than other three sequences. (STIR and T2W FSE, Z = -4.000, p definition of the plaques rather than other three sequences. This study shows that in the setting of a 1.5 T magnet field, STIR significantly has a superiority over both of the PSIR reconstructions (i.e. real and magnitude) for the detection as well as the boundary definition of the cervical cord lesions of MS. These results have a good relevance to clinical practice by using MRI scanners and sequences routinely available, however, it is discrepant with other reports performed by 3 T Magnet fields.

    Multifocal tumors within the same parotid gland are very rare. We treated 13 patients with multiple tumorous lesions within the unilateral parotid gland. We evaluated the multiple nodules by CT-sialography or magnetic resonance imaging (MRI). These imagings showed clearly two or more distinct nodular-appearing lesions. Recurrent pleomorphic adenoma (6 patients) was predominant, followed by Whartin's tumor (3 patients). The other lesions were two differential parenchymal tumors (polymorphous low grade adenoma/adenoma) within the same gland, a malignant lymphoma, a squamous cell carcinoma metastatic to the gland, and a tuberculous lesion. On palpitation, 9 of the patients had an unilateral tumor, one a palpable parotid mass in the gland, and the other four had two or more tumors in the unilateral gland. The patients with intra-parotid lymph node and metastatic lesions had extra-parotid cervical adenopathy. The clinical features and the differential diagnosis of the unilateral multiple tumors lesions of the parotid gland are discussed. (author)

    2018-01-01

    A 13-year-old male presents for evaluation of a right-sided posterolateral neck mass, first noted four years prior to presentation; incisional biopsy two years ago suggested a benign lymph node. Recent growth and increased pain prompted referral to our tertiary care center. MR imaging revealed a densely calcified mass in the right posterior paraspinous muscles with intense enhancement with gadolinium contrast, approximately 5 cm × 2.8 cm x 4.6 cm. Incisional biopsy showed leiomyoma with extensive dystrophic calcifications. This case describes a rare finding of extraesophageal leiomyoma of the neck; this is only the second such case reported in a pediatric patient. Copyright © 2017 Elsevier B.V. All rights reserved.

    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 (EMRA(null/dim)), and the CD16+/CD56 + CD8+ T cells of women with low-grade cervical lesions are altered at a systemic level. We enrolled in this study women controls and women with Human papilloma virus infection (HPV-I) without associated cellular neoplastic changes and with Cervical Intraepithelial Neoplastic-I (CIN-I). Flow cytometry (FC) was performed for measurement of CD28-, memory subset, and NK-like CD8 + T cells, and IL-17, IFN-gamma, Tumor necrosis factor (TNF)-alpha, Interleukin (IL)-10, IL-6, IL-4, and IL-2. Finally, we genotyped the HPV. The CIN-I group increased the CD8 + CD28- and CD16+/56+ T cell percentage compared with that of HPV-I and controls (p levels among all groups. Increased levels of CD28-, EMRA(null/dim), and CD16+/CD56 + CD8+ T cells of peripheral blood in women with CIN-I may be associated with persistent HPV infection and could exert an influence on progression to cervical cancer.

    More information is needed about time between sexual initiation and human papillomavirus (HPV) infection and development of cervical precancer. The objectives were to investigate the time between first sexual activity and detection of first cervical HPV infection or development of first cervical intraepithelial neoplasia (CIN), and associated factors in women from the double-blind, multinational, 4-year PATRICIA trial. PATRICIA enroled women aged 15-25 years with no more than 6 lifetime sexual partners. Women were randomized 1:1 to the HPV-16/18 AS04-adjuvanted vaccine or to control, but only women from the control arm who began sexual intercourse during the study or within 6 months before enrolment, and had no HPV infection detected before the recorded date of their first sexual intercourse, were included in the present analysis. The time between onset of sexual activity and detection of the first cervical HPV infection or development of the first CIN lesion was analyzed using Kaplan-Meier and univariate and multivariable Cox proportional-hazards models. A total of 9337 women were enroled in the control arm of PATRICIA of whom 982 fulfilled the required inclusion criteria for analysis. A cumulative total of 28%, 44%, and 62% of the subjects had HPV infection within 12, 24, and 48 months, respectively. The overall incidence rate was 27.08 per 100 person-years. The most common oncogenic types associated with 6-month persistent infection were HPV-16 (incidence rate: 2.74 per 100 person-years), HPV-51 (2.70), HPV-52 (1.66), HPV-66 (1.14), and HPV-18 (1.09). Increased infection risk was associated with more lifetime sexual partners, being single, Chlamydia trachomatis history, and duration of hormone use. CIN1+ and CIN2+ lesions were most commonly associated with HPV-16, with an overall incidence rate of 1.87 and 1.07 per 100 person-years, respectively. Previous cervical HPV infection was most strongly associated with CIN development. More than 25% of women were

    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.)

  16. External validation of a publicly available computer assisted diagnostic tool for mammographic mass lesions with two high prevalence research datasets.

    Benndorf, Matthias; Burnside, Elizabeth S; Herda, Christoph; Langer, Mathias; Kotter, Elmar

    2015-08-01

    Lesions detected at mammography are described with a highly standardized terminology: the breast imaging-reporting and data system (BI-RADS) lexicon. Up to now, no validated semantic computer assisted classification algorithm exists to interactively link combinations of morphological descriptors from the lexicon to a probabilistic risk estimate of malignancy. The authors therefore aim at the external validation of the mammographic mass diagnosis (MMassDx) algorithm. A classification algorithm like MMassDx must perform well in a variety of clinical circumstances and in datasets that were not used to generate the algorithm in order to ultimately become accepted in clinical routine. The MMassDx algorithm uses a naïve Bayes network and calculates post-test probabilities of malignancy based on two distinct sets of variables, (a) BI-RADS descriptors and age ("descriptor model") and (b) BI-RADS descriptors, age, and BI-RADS assessment categories ("inclusive model"). The authors evaluate both the MMassDx (descriptor) and MMassDx (inclusive) models using two large publicly available datasets of mammographic mass lesions: the digital database for screening mammography (DDSM) dataset, which contains two subsets from the same examinations-a medio-lateral oblique (MLO) view and cranio-caudal (CC) view dataset-and the mammographic mass (MM) dataset. The DDSM contains 1220 mass lesions and the MM dataset contains 961 mass lesions. The authors evaluate discriminative performance using area under the receiver-operating-characteristic curve (AUC) and compare this to the BI-RADS assessment categories alone (i.e., the clinical performance) using the DeLong method. The authors also evaluate whether assigned probabilistic risk estimates reflect the lesions' true risk of malignancy using calibration curves. The authors demonstrate that the MMassDx algorithms show good discriminatory performance. AUC for the MMassDx (descriptor) model in the DDSM data is 0.876/0.895 (MLO/CC view) and AUC

Methods: We retrospectively reviewed 49 patients with multilevel CSM who had undergone expansive open-door laminoplasty with lateral mass screws fixation and fusion in our hospital between February 2008 and February 2012. The average follow-up period was 4.6 years. The clinical data of patients, including age, sex, operation records, pre- and postoperation Japanese Orthopedic Association (JOA scores, cervical spine canal stenosis, and cervical curvature, were collected. Increased signal intensity (ISI on T2-weighted magnetic resonance imaging and ossification of the posterior longitudinal ligament were also observed. Paired t-test was used to analyze the treatment effectiveness and recovery of neuronal function. The prognostic factors were analyzed with multivariable linear regression model. Results: Forty-nine patients with CSM with a mean age of 59.44 years were enrolled in this study. The average of preoperative JOA score was 9.14±2.25, and postoperative JOA score was 15.31±1.73. There was significant difference between the pre- and postoperative JOA scores. The clinical improvement rate was 80.27%. On follow-up, five patients had complaints of neck and shoulder pain, but no evidence of C5 nerve palsy was found. Developmental cervical spine canal stenosis was present in all patients before surgery. Before surgery, ISI was observed in eight patients, while ossification of the posterior longitudinal ligament was found in 12 patients. The average of preoperative cervical

    An unusual case of myositis ossificans traumatica lesion located in the paraspinal region is reported. Despite the contiguity of the lesion with the cervical vertebrae and ominous appearance of the biopsy material, the history of antecedent trauma and computed tomography findings allowed preoperative accurate diagnosis. To our knowledge, myositis ossificans traumatica located in the cervical paraspinal region is very rare. (orig.)

    Dieulafoy's lesion, also known as a caliber-persistent artery, is a shallow, small, and rare lesion that occurs along the lesser curvature of proximal stomach. It is rare for a Dieulafoy's lesion to present as a mass-like lesion that coexists with gastric cancer. To our best knowledge, we report the first case and histopathological pictures of a mass-like Dieulafoy's lesion coexisting with advanced gastric cancer in the antrum of the stomach. A 57-year-old female presented with a 6-month history of intermittent epigastric dull pain and dyspepsia. Subsequent upper gastrointestinal endoscopy revealed a friable mass that was located between the distal antrum and the pyloric ring. Biopsy revealed it to be an intestinal type adenocarcinoma. Subtotal gastrectomy was performed after neoadjuvant chemotherapy. Grossly, a large irregular plaque-like tumor lesion was noted at the anterior wall of the distal antrum and pylorus ring near the lesser curvature, measuring 5.6 × 4.8 × 1.0 cm. Histopathological examination of the resected stomach revealed that the plaque-like lesion largely consisted of numerous abnormally large-caliber and tortuous arteries in the submucosa. The increased fibrosis of the submucosa resulted in the formation of elevated plaque. The intestinal type adenocarcinoma was noted to be largely confined to the mucosa layer, with focal submucosal and muscular propria involvement. The patient was discharged one week after the subtotal gastrectomy, and she was alive and well 17 months after discharge, with no major complications. This is the first case of a mass-like Dieulafoy's lesion coexisting with advanced gastric cancer at the distal antrum area. This case highlights the possibility of life-threatening gastric bleeding after mucosal resection or biopsy that could be encountered by endoscopists.

    OBJECTIVE Given the increasing prevalence of obesity, more patients with a high body mass index (BMI) will require surgical treatment for degenerative spinal disease. In previous investigations of lumbar spine pathology, obesity has been associated with worsened postoperative outcomes and increased costs. However, few studies have examined the association between BMI and postoperative outcomes following anterior cervical discectomy and fusion (ACDF) procedures. Thus, the purpose of this study was to compare surgical outcomes, postoperative narcotics consumption, complications, and hospital costs among BMI stratifications for patients who have undergone primary 1- to 2-level ACDF procedures. METHODS The authors retrospectively reviewed a prospectively maintained surgical database of patients who had undergone primary 1- to 2-level ACDF for degenerative spinal pathology between 2008 and 2015. Patients were stratified by BMI as follows: normal weight (costs. Regression analyses were controlled for preoperative demographic and procedural characteristics. RESULTS Two hundred seventy-seven patients were included in the analysis, of whom 20.9% (n = 58) were normal weight, 37.5% (n = 104) were overweight, 24.9% (n = 69) were obese I, and 16.6% (n = 46) were obese II-III. A higher BMI was associated with an older age (p = 0.049) and increased comorbidity burden (p = 0.001). No differences in sex, smoking status, insurance type, diagnosis, presence of neuropathy, or preoperative VAS pain scores were found among the BMI cohorts (p > 0.05). No significant differences were found among these cohorts as regards operative time, intraoperative blood loss, length of hospital stay, and number of operative levels (p > 0.05). Additionally, no significant differences in postoperative narcotics consumption, VAS score improvement, complication rates, arthrodesis rates, reoperation rates, or total direct costs existed across BMI stratifications (p > 0.05). CONCLUSIONS Patients with a

    Injuries of the subaxial cervical spine including facet joints and posterior ligaments are common. Potential surgical treatments consist of anterior, posterior, or anterior-posterior fixation. Because each approach has its advantages and disadvantages, the best treatment is debated. This biomechanical cadaver study compared the effect of different facet joint injuries on primary stability following anterior plate fixation. Fractures and plate fixation were performed on 15 fresh-frozen intact cervical spines (C3-T1). To simulate a translation-rotation injury in all groups, complete ligament rupture and facet dislocation were simulated by dissecting the entire posterior and anterior ligament complex between C-4 and C-5. In the first group, the facet joints were left intact. In the second group, one facet joint between C-4 and C-5 was removed and the other side was left intact. In the third group, both facet joints between C-4 and C-5 were removed. The authors next performed single-level anterior discectomy and interbody grafting using bone material from the respective thoracic vertebral bodies. An anterior cervical locking plate was used for fixation. Continuous loading was performed using a servohydraulic test bench at 2 N/sec. The mean load failure was measured when the implant failed. In the group in which both facet joints were intact, the mean load failure was 174.6 ± 46.93 N. The mean load failure in the second group where only one facet joint was removed was 127.8 ± 22.83 N. In the group in which both facet joints were removed, the mean load failure was 73.42 ± 32.51 N. There was a significant difference between the first group (both facet joints intact) and the third group (both facet joints removed) (p cadaver study, primary stability of anterior plate fixation for dislocation injuries of the subaxial cervical spine was dependent on the presence of the facet joints. If the bone in one or both facet joints is damaged in the clinical setting, anterior plate

    Full Text Available A thyroid mass, most often a non toxic colloid goiter or occasionally an adenoma, is not an unusual finding below the level of the thoracic inlet.1 In 1992 Creswell and Wells estimated that these tumors comprise 5.8% of all mediastinal lesions.1 There is no standard definition for thyroid glands extending below the thoracic inlet, but such masses descend from their original cervical location for more than 2 or 3 cm below the thoracic inlet, and are not truly primary tumors of the mediastinum. They preserve the connection between the thoracic and cervical portion and receive their blood supply from the neck.2,3 In 1940, the seminal report of Wakeley and Mulvany divided intrathoracic thyroid masses into 3 types; (1”Small substernal extension” of a mainly cervical mass, (2 “Partial” intrathoracic, in which the major portion of the mass is situated within the thorax, and (3”Complete” in which all of the mass lies within the thoracic cavity.

    The control arm of the phase III VIVIANE (Human PapillomaVIrus: Vaccine Immunogenicity ANd Efficacy; NCT00294047) study in women >25 years was studied to assess risk of progression from cervical HPV infection to detectable cervical intraepithelial neoplasia (CIN). The risk of detecting CIN associated with the same HPV type as the reference infection was analysed using Kaplan-Meier and multivariable Cox models. Infections were categorised depending upon persistence as 6-month persistent infection (6MPI) or infection of any duration. The 4-year interim analysis included 2,838 women, of whom 1,073 (37.8%) experienced 2,615 infections of any duration and 708 (24.9%) experienced 1,130 6MPIs. Infection with oncogenic HPV types significantly increased the risk of detecting CIN grade 2 or greater (CIN2+) versus non-oncogenic types. For 6MPI, the highest risk was associated with HPV-33 (hazard ratio [HR]: 31.9 [8.3-122.2, p 25 years in this study was similar to that in women 15-25 years in PATRICIA. © 2015 The Authors and GlaxoSmithKline.

    alcanzar la fusión y la estabilidad de la columna cervical, y con el conocimiento de la anatomía y de la técnica quirúrgica es posible obtenerse excelentes resultados.OBJECTIVE: To present the surgical results of a case series of upper cervical spine stabilization with the use of lateral mass screws of the atlas. 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.

    It has been confirmed, that there is a causal relationship between persistent infection of high risk human papillomavirus (HR-HPV) and the development of cervical cancer. In population of women older than 30 years HPV infection becomes a significant etiological factor of precancerous lesion of the cervix, but HPV infection may spontaneously regress in the majority of the cases. The analysed study group consisted of 397 samples with cytological diagnosis of atypical squamous cells of unknown significance (ASCUS). All cases underwent HPV DNA testing using the Hybrid Capture 2 (HC2) assay. We analysed prevalence of HR-HPV and a viral load expressed as relative light units/cut off ratio (RLU/CO) in different age groups with cytological diagnoses of ASCUS. The prevalence of HR-HPV with cytological diagnoses of ASCUS was detected in 44 %. The prevalence of HR-HPV between patients aged 17-29 and between patients aged 30-40 was 55 % and 48 % respectively and we detected significant reduction of prevalence (28 %) in patients older than 41 years. Based on the results of presented study we assumed that age the 40 and over is crucial for the development of serious precancerous lesions in Slovakia, thus this age group is the most suitable for HPV triage of ASCUS. As a refinement of that type of ASCUS triage we recommend to add to the algorithm quantitative measurement of viral load in the specimens in the form of RLU/CO ratio (Fig. 3, Ref. 27).

    Branchial pouch-derived anomalies may arise from remnants of the first, second, or third/fourth branchial arches. Branchial pouch-related structures are found within the thyroid gland in the form of solid cell rests, epithelial lined cyst with or without an associated lymphoid component, thymic and/or parathyroid tissue, and less commonly in the form of heterotopic cartilage. We present a rare case of left solid thyroid swelling nearby two cervical nodules in a seven-year-old female with a clinical diagnosis suggestive of malignant thyroid tumor with metastasis to the cervical lymph nodes. Histopathological examination revealed that it was compatible with third/fourth branchial pouch-derived anomaly composed of mature cartilage and thymic and parathyroid tissues for clinical and radiological correlations.

    Full Text Available The control arm of PATRICIA (PApilloma TRIal against Cancer In young Adults, NCT00122681 was used to investigate the risk of progression from cervical HPV infection to cervical intraepithelial neoplasia (CIN or clearance of infection, and associated determinants.Women aged 15-25 years were enrolled. A 6-month persistent HPV infection (6MPI was defined as detection of the same HPV type at two consecutive evaluations over 6 months and clearance as ≥2 type-specific HPV negative samples taken at two consecutive intervals of approximately 6 months following a positive sample. The primary endpoint was CIN grade 2 or greater (CIN2+ associated with the same HPV type as a 6MPI. Secondary endpoints were CIN1+/CIN3+ associated with the same HPV type as a 6MPI; CIN1+/CIN2+/CIN3+ associated with an infection of any duration; and clearance of infection. The analyses included 4825 women with 16,785 infections (3363 women with 6902 6MPIs. Risk of developing a CIN1+/CIN2+/CIN3+ associated with same HPV type as a 6MPI varied with HPV type and was significantly higher for oncogenic versus non-oncogenic types.

Previous or concomitant infection or CIN1+ also increased the risk. HPV-16 and HPV-33 have by far the highest risk of progression to CIN3+, and HPV-16 and HPV-31 have the lowest chance of clearance.

    2012-10-01

    Cervical cancer remains a major reproductive health problem among women especially in developing countries where about 190,000 women die from this disease annually. Despite efforts to reduce the burden of this disease, most attempts in low-resourced countries have not been successful partly from lack of awareness by women of this common cancer, as well as the role the human papilloma virus (HPV) plays in its aetiology and pathogenesis. To determine knowledge, attitudes and practice of women in Trinidad (a developing country) on HPV, cervical cancer and the HPV vaccine, we conducted a cross-sectional survey among 426 women in the reproductive age. A majority (58.4%) of participants had attained secondary level education. Whereas 326 (76.5%) women knew of cervical cancer, only 108 (25.4%) were aware of HPV and 68 (15.9%) knew of the association between HPV and cervical cancer. This study highlights the limited awareness of Trinidadian women with respect to HPV and its implication in cervical cancer aetiology. If the scourge of cervical cancer is to be adequately addressed, especially in low-resourced countries, then mass educational programmes on HPV, cervical cancer prevention, including screening and early detection and treatment of pre-cancerous lesions of the cervix, must be given high priority.

    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.

    Human papillomavirus (HPV)-mediated suppression of Langerhans cell (LC) function can lead to persistent infection and development of cervical intraepithelial neoplasia (CIN). Women with HPV-induced high-grade CIN2/3 have not mounted an effective immune response against HPV, yet it is unknown if LC-mediated T cell activation from such women is functionally impaired against HPV. We investigated the functional activation of in vitro generated LC and their ability to induce HPV16-specific T cells from CIN2/3 patients after exposure to HPV16 followed by treatment with stabilized Poly-I:C (s-Poly-I:C). LC from patients exposed to HPV16 demonstrated a lack of costimulatory molecule expression, inflammatory cytokine secretion, and chemokine-directed migration. Conversely, s-Poly-I:C caused significant phenotypic and functional activation of HPV16-exposed LC, which resulted in de novo generation of HPV16-specific CD8(+) T cells. Our results highlight that LC of women with a history of persistent HPV infection can present HPV antigens and are capable of inducing an adaptive T cell immune response when given the proper stimulus, suggesting that s-Poly-I:C compounds may be attractive immunomodulators for LC-mediated clearance of persistent HPV infection.

  8. Comparison Of Lateral Mass Screw Fixation Technique And Hartshill Rectangle Technique In The Treatment Of Sub-Axial Cervical Spine Fractures

    Mohit KM

    2012-11-01

    Full Text Available INTRODUCTION: Cervical injury in a polytrauma patient is one of the most critical injuries. The aim of this study was to compare the lateral mass screw technique with the Hartshill rectangle technique for treatment of such cases. MATERIALS AND METHODS: This prospective study consisted of 40 patients. Both groups were followed for three years clinically and radiologically. RESULTS: In the lateral mass technique, there were no cases of vertebral artery injury, radiculopathy, screw pullout, dural tears, residual kyphosis or persistent pain. In the Hartshill technique 3 patients experienced intra- operative dural tears, 1 case of wire breakage at the six months follow up, 6 patients with persistent neck pain and 1 with worsening neurological status. One hundred per cent fusion was achieved in both groups. There was significant radiation exposure in the lateral mass group. Post-operative immobilisation was required only in the Hartshill. CONCLUSION: Lateral mass screw technique is definitely a relatively better procedure. But Hartshill rectangle still stands out in certain practical situations.

  9. Hyperparathyroidism caused by distant pulmonary lesions and parathyromatosis after ethanol injection/parathyroidectomy for secondary hyperparathyroidism.

    Nakamura, Michio; Tanaka, Kiho; Fujii, Takeshi

    2017-07-01

    Secondary hyperparathyroidism (SHPT) treatment includes parathyroidectomy and percutaneous ethanol injection therapy (PEIT), which are invasive procedures. The condition in which benign hyperfunctioning parathyroid tissue is distributed throughout the neck and mediastinum is termed parathyromatosis. Here, we present the case of a 51-year-old woman who began hemodialysis in 1986 due to chronic kidney disease of unknown etiology and developed SHPT in 1999. She underwent 6 rounds of PEIT followed by total a parathyroidectomy with partial forearm autotransplantation. Between 2011 and 2013, surgeons removed several nodules from her pulmonary and cervical regions and the transplanted masses from her forearm; all showed hyperplasia but exhibited no histological evidence of malignancy. Damage to the parathyroid capsule after repeated PEITs may cause local cervical recurrence and pulmonary lesions, although distant lesions are extremely rare in SHPT. This case is of interest due to the possible association between PEIT and parathyromatosis and distal lesions. © 2017 International Society for Hemodialysis.

    Pregnancy and cervical carcinoma occurring concomitantly causes therapeutic and ethical dilemmas. The management for this situation will depend on the gestational age at the time of diagnosis, disease staging, size of the lesion and the patient’s wish to maintain pregnancy and fertility. Review of the literature suggest that pregnancy does not seem to influence the prognosis of cervical cancer. (author)

  11. Effects of cervical low-frequency electrical stimulation with various waveforms and densities on body mass, liver and kidney function, and death rate in ischemic stroke rats

    2011-01-01

    Low-frequency electrical stimulation has resulted in favorable effects in the treatment of post-stroke dysphagia. However, the safety of cervical low-frequency electrical stimulation remains unclear because of numerous nerves and blood vessels in the neck. In the present study, rats with ischemic stroke underwent low-frequency electrical stimulation, and systemic and local effects of electrical stimulation at different densities and waveforms were investigated. Electrical stimulation resulted in no significant effects on body mass, liver or kidney function, or mortality rate. In addition, no significant adverse reaction was observed, despite overly high intensity of low-frequency electrical stimulation, which induced laryngismus, results from the present study suggested that it is safe to stimulate the neck with a low-frequency electricity under certain intensities.

  12. The effect of aging of formalin-fixed paraffin-embedded tissues on the in situ hybridization and immunohistochemistry signals in cervical lesions.

    Nuovo, Allison J; Garofalo, Michela; Mikhail, Alexandria; Nicol, Alcina F; Vianna-Andrade, Cecilia; Nuovo, Gerard J

    2013-09-01

    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.

    An unusual case of myositis ossificans traumatica lesion located in the paraspinal region is reported. Despite the contiguity of the lesion with the cervical vertebrae and ominous appearance of the biopsy material, the history of antecedent trauma and computed tomography findings allowed preoperative accurate diagnosis. To our knowledge, myositis ossificans traumatica located in the cervical paraspinal region is very rare. (orig.) With 4 figs., 16 refs.

    The purpose of this article was to briefly summarize the most important characteristics of non-carious cervical lesions, as well as the etiological factors that lead to their formation. Cervical area represents one of the most sensitive parts of the tooth due to the specific position, as well as the structure and thickness of hard tissue. It is less resistant to various chemical and mechanical stimuli, and as a result the lesions in this area are frequently encountered in everyday practice.

Patients and methods: The study period was from June 2002 to March 2014. The subjects were 28 patients with a stage II bulky mass in the NAC group and 17 such patients in the Ope group. The chi-square test was used to compare operative time, volume of intraoperative blood loss, use of blood transfusion, and time from surgery to discharge between the two groups. Moreover, the log-rank test using the Kaplan–Meier method was performed to compare disease-free survival (DFS and overall survival (OS between the groups. Results: There were no statistically significant differences between the two groups in operative time, volume of intraoperative blood loss, or use of blood transfusion. However, the time from surgery to discharge was 18 days (14–25 days in the NAC group and 25 days (21–34 days in the Ope group; the patients in the NAC group were discharged earlier (P=0.032. The hazard ratio for DFS in the NAC group as compared with that in the Ope group was 0.36 (95% CI 0.08–0.91, and the 3-year DFS rates were 81.2% and 41.0%, respectively (P=0.028. Moreover, the hazard ratio for OS was 0.39 (95% CI 0.11–1.24, and the 3-year OS rates were 82.3% and 66.4%, respectively (P=0.101. Conclusion: NAC with cisplatin and irinotecan was confirmed to prolong DFS as compared with RH alone. The results of this study suggest that NAC might be a useful adjunct to surgery in the treatment of stage II squamous

    The purpose of this study was to evaluate the usefulness of a computer-aided diagnosis (CAD) scheme for improving the performance of clinicians to diagnose non-mass lesions appearing as hypoechoic areas on breast ultrasonographic images. The database included 97 ultrasonographic images with hypoechoic areas: 48 benign cases [benign lesion with benign mammary tissue or fibrocystic disease (n = 20), fibroadenoma (n = 11), and intraductal papilloma (n = 17)] and 49 malignant cases [ductal carcinoma in situ (n = 17) and invasive ductal carcinoma (n = 32)]. Seven clinicians, three expert breast surgeons, and four general surgeons participated in the observer study. They were asked their confidence level concerning the possibility of malignancy in all 97 cases with and without the use of the CAD scheme. Receiver operating characteristic (ROC) analysis was performed to evaluate the usefulness of the CAD scheme. The areas under the ROC curve (AUC) improved for all observers when they used the CAD scheme and increased from 0.649 to 0.783 (P = 0.0167). Notably, the AUC for the general surgeon group increased from 0.625 to 0.793 (P = 0.045). This study showed that the performance of clinicians to diagnose non-mass lesions appearing as hypoechoic areas on breast ultrasonographic images was improved by the use of a CAD scheme.

  1. Cervical cancer screening at crossroads

    Cervical screening has been one of the most successful public health prevention programmes. For 50 years, cytology formed the basis for screening, and detected cervical intraepithelial lesions (CIN) were treated surgically to prevent progression to cancer. In a high-risk country as Denmark......, screening decreased the incidence of cervical cancer from 34 to 11 per 100,000, age-standardized rate (World Standard Population). Screening is, however, also expensive; Denmark (population: 5.6 million) undertakes close to half a million tests per year, and has 6-8 CIN-treated women for each prevented...... cancer case. The discovery of human papillomavirus (HPV) as the cause of cervical cancer dramatically changed perspectives for disease control. Screening with HPV testing was launched around 1990, and preventive HPV vaccination was licensed in 2006. Long-term randomized controlled trials (RCT...

    2018-01-01

    To compare the diagnostic performance of strain and shear wave elastography of breast masses for quantitative assessment in differentiating benign and malignant lesions and to evaluate the diagnostic accuracy of combined strain and shear wave elastography. Between January and February 2016, 37 women with 45 breast masses underwent both strain and shear wave ultrasound (US) elastographic examinations. The American College of Radiology Breast Imaging Reporting and Data System (BI-RADS) final assessment on B-mode US imaging was assessed. We calculated strain ratios for strain elastography and the mean elasticity value and elasticity ratio of the lesion to fat for shear wave elastography. Diagnostic performances were compared by using the area under the receiver operating characteristic curve (AUC). The 37 women had a mean age of 47.4 years (range, 20-79 years). Of the 45 lesions, 20 were malignant, and 25 were benign. The AUCs for elasticity values on strain and shear wave elastography showed no significant differences (strain ratio, 0.929; mean elasticity, 0.898; and elasticity ratio, 0.868; P > .05). After selectively downgrading BI-RADS category 4a lesions based on strain and shear wave elastographic cutoffs, the AUCs for the combined sets of B-mode US and elastography were improved (B-mode + strain, 0.940; B-mode + shear wave; 0.964; and B-mode, 0.724; P shear wave elastography showed significantly higher diagnostic accuracy than each individual elastographic modality (P = .031). These preliminary results showed that strain and shear wave elastography had similar diagnostic performance. The addition of strain and shear wave elastography to B-mode US improved diagnostic performance. The combination of strain and shear wave elastography results in a higher diagnostic yield than each individual elastographic modality. © 2017 by the American Institute of Ultrasound in Medicine.

    1997-01-01

    Spondylolysis of the cervical spine is a rare disorder that is characterized by a defect in the articular mass between the superior and inferior facets of a cervical vertebra. It is considered to be congenital because it is usually associated with dysplastic changes, especially involving the posterior arch of the vertebra, which differentiates it from its traumatic equivalent. We present two cases of spondylolysis of the cervical spine without spondylolisthesis, which were studied by means of magnetic resonance (MR) and computerized tomography (CT). One patient showed contralateral involvement at two levels and the other had a single lesion presenting canal stenosis with chronic spinal cord compression, an unusual association in previously reported series. the combination of MR and CT makes it possible to limit the spectrum of bone changes and their impact on the spinal cord in these patients.

    2016-08-01

    Full Text Available Background: Cervical carcinoma is a common cause of death in India. It is presented by spectrum of precancerous lesions, called cervical intraepithelial neoplasia (CIN. Cervical cytological screening is designed to detect over 90% of cytological abnormalities. It has been established that cervical cancers can be diagnosed at the pre-invasive stage with adequate, repetitive cytological screening. Keeping in view of the importance of cervical PAP abnormalities & by classifying them by Bethesda terminology; correlation with clinical findings & histopathological findings was done. Methods: All cervical Pap smears reported in Department of Pathology from 1st August 2015 to 31st July 2016, were prospectively studied and classified according to revised Bethesda terminology, 2014. Also cytoradiological and clinico-cytological, cytohistological correlation was studied. Results: Due to increasing awareness among masses inculcated by social workers, most of the patients for PAP smear cytology came for routine screening to rule out cervical lesions followed by clinical finding of per-vaginal discharge. The 350 screened patients were in the third and fourth decades of life. 99/350 cases were subjected to USG study, with maximum number of cases (34 cases showing normal study, followed by cases with ovarian cysts and fatty liver disease. Negative for intra-epithelial lesion (NILM without any denotable organism was the pre-dominant cytological finding of PAP smear study followed by cases of NILM with bacterial vaginosis (30 cases with two malignancies. Intra-epithelial lesions (IELs were noted in 16.86%. ASCUS comprised 12.29%, ASC-H comprised 1.14%, L-SIL comprised 1.71%, HSIL comprised 1.43%, Atrophic cervical smears comprised 5.14%, Squamous cell carcinoma comprised 0.29% cases. ASC/LSIL ratio was 7.8 and inadequacy rate for PAP smear study was 7.43%. Cytologyhistopathology correlation was possible in 62 cases. Conclusion: Classification of cervical PAP

    Objective: To evaluate and compare the screening performance of primary high-risk HPV(HR-HPV) screening and HR-HPV screening plus liquid-based cytology (LBC) cotesting in diagnosis of cervical cancer and precancerous lesions (CIN2+). Methods: We pooled 17 population-based cross-sectional studies which were conducted across China from 1999 to 2008. After obtaining informed consent, all women received liquid-based cytology(LBC)testing, HR-HPV DNA testing. Totally 28 777 women with complete LBC, HPV and biopsy results were included in the final analysis. Screening performance of primary HR-HPV DNA screening and HPV screening plus LBC co-testing in diagnosis of CIN2+ were calculated and compared among different age groups. Results: Among the whole population, the detection rates of primary HR-HPV screening and HR-HPV screening plus LBC co-testing are 3.05% (879 CIN2+) and 3.13%(900 CIN2+), respectively. The sensitivity were 96.4% and 98.7% (χ(2)=19.00, PHPV screening performed better than co-testing (AUC were 0.913 and 0.888; Z= 6.16, PHPV screening, co-testing showed significantly higher colposcopy referral rates (16.5% and 23.6%, respectively, χ(2)=132.00, PHPV screening in diagnosis of CIN2+, and was 12.5 (15.7%(288 cases) vs 1.3%(23 cases)) times as much as the detection rate of HR-HPV screening plus cytology contesting. Conclusion: Compared with primary HR-HPV screening, HR-HPV screening plus cytology co-testing does not show better results in the screening performance for CIN2+ detection, and the cost-effectiveness is not good enough, especially in younger age group.

    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.)

    Link, J.; Steffens, J.C.; Mueller-Huelsbeck, S.; Brossmann, J.; Heller, M.

    1996-01-01

    In 386 selective angiograms of cervical vessels fibromuscular dysplasia was revealed in 4 female patients in the age of 30-54 years. FMD was located in the carotid artery (n=5) and in the vertebral artery (n=2) with a total of 8 lesions. 6/8 of the lesions of the seven cervical vessels were located typically in the mid cervical portion of the vessels and 2/6 lesions were located in the atlas loop of the vertebral artery. 4 lesions showed moderate stenosis and 4 vessels showed only mild stenosis. These patterns which demonstrated the typical morphology of fibromuscular dysplasia with alternating irregular zones of widening and narrowing were evaluated well with MR angiography, the others were missed.

    2015-01-01

    To investigate whether the diagnostic performance of lesion-to-fat elasticity ratio (Eratio) was affected by the location of the reference fat. For 257 breast masses in 250 women who underwent shear-wave elastography before biopsy or surgery, multiple Eratios were measured with a fixed region-of-interest (ROI) in the mass along with multiple ROIs over the surrounding fat in different locations. Logistic regression analysis was used to determine that Eratio was independently associated with malignancy adjusted for the location of fat ROI (depth, laterality, and distance from lesion or skin). Mean (Emean) and maximum (Emax) elasticity values of fat were divided into four groups according to their interquartile ranges. Diagnostic performance of each group was evaluated using the area under the ROC curve (AUC). False diagnoses of Eratio were reviewed for ROIs on areas showing artifactual high or low stiffness and analyzed by logistic regression analysis to determine variables (associated palpable abnormality, lesion size, the vertical distance from fat ROI to skin, and elasticity values of lesion or fat) independently associated with false results. Eratio was independently associated with malignancy adjusted for the location of fat ROI (P<0.0001). Among four groups of fat elasticity values, the AUC showed no significant difference (<25th percentile, 25th percentile~median, median~75th percentile, and ≥75th percentile; 0.973, 0.982, 0.967, and 0.954 for Emean; 0.977, 0.967, 0.966, and 0.957 for Emax). Fat elasticity values were independently associated with false results of Eratio with the cut-off of 3.18 from ROC curve (P<0.0001). ROIs were set on fat showing artifactual high stiffness in 90% of 10 false negatives and on lesion showing vertical striped artifact or fat showing artifactual low stiffness in 77.5% of 71 false positives. Eratio shows good diagnostic performance regardless of the location of reference fat, except when it is placed in areas of artifacts.

    A 6-year-old spayed female miniature schnauzer presented with generalized seizures and progressive multifocal intracranial neurologic disease. Thoracic radiographs and computed tomography (CT) revealed a large solitary pulmonary mass within the right cranial lung lobe. On brain magnetic resonance imaging (MRI), a solitary intraparenchymal mass within the left piriform lobe had a "target" appearance on both pre- and postcontrast sequences. Cerebrospinal fluid was unremarkable and histopathology indicated both masses represented histiocytic sarcoma. This case represents an uncommonly reported MRI appearance of histiocytic sarcoma in the canine brain and a large, solitary-appearing pulmonary histiocytic sarcoma in the same dog. © 2017 American College of Veterinary Radiology.

  15. Nasopharyngeal Carcinoma with Cystic Cervical Metastasis Masquerading as Branchial Cleft Cyst: A Potential Pitfall in Diagnosis and Management.

    Most metastatic lymph nodes from head and neck malignancy are solid. Cystic nodes are found in 33% - 61% of carcinomas arise from Waldeyer's ring, of which only 1.8% - 8% originate are from the nasopharynx. Some cystic cervical metastases were initially presumed to be branchial cleft cyst. This case report aims to highlight the unusual presentation of cystic cervical metastasis secondary to nasopharyngeal carcinoma in a young adult. The histopathology, radiological features and management strategy were discussed. A 36-year-old man presented with a solitary cystic cervical swelling, initially diagnosed as branchial cleft cyst. Fine needle aspiration yielded 18 ml of straw-coloured fluid. During cytological examination no atypical cells were observed. Computed tomography of the neck showed a heterogeneous mass with multiseptation medial to the sternocleidomastoid muscle. Histopathological examination of the mass, post excision, revealed a metastatic lymph node. A suspicious mucosal lesion at the nasopharynx was detected after repeated thorough head and neck examinations and the biopsy result confirmed undifferentiated nasopharyngeal carcinoma. Cystic cervical metastasis may occur in young patients under 40 years. The primary tumour may not be obvious during initial presentation because it mimicks benign branchial cleft cyst clinically. Retrospective review of the computed tomography images revealed features that were not characteristic of simple branchial cleft cyst. The inadequacy of assessment and interpretation had lead to the error in diagnosis and subsequent management. Metastatic head and neck lesion must be considered in a young adult with a cystic neck mass.

    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.

    Cervical cerclage aims to strengthen not only the mechanical properties of the cervix, but also its immunological and anti-infectious functions. The demonstration of a strong interrelation between cervical insufficiency as well as decreased cervical length at endo-vaginal ultrasonography and infection has changed the indications cerclage. Actually we can distinguish three indications for cerclage: prophylactic, for obstetrical history; therapeutic, for shortened cervical length at ultrasonography in patients at risk and; emergency cerclage in case of threatening cervix at physical examination. The McDonald's technique is the most recommended. In case of failure, it is proposed to realize cerclage at a higher level on the cervix either by vaginal or abdominal route.

  2. 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.

  3. Human papilloma virus infection and cervical dysplasia.

    Melinte-Popescu, Alina; Costăchescu, Gh

    2012-01-01

    Pap testing is considered to be the best screening tool for cervical cancer but there is currently great interest in the possible application of human papilloma virus (HPV) testing to supplement Pap screening for cervical cancer. To determine the prevalence of high-risk HPV types in the studied population and to explore the association between high-risk HPV types and cervical dysplasia. Cross-sectional study conducted at the Iasi Cuza Voda Obstetrics-Gynecology Hospital and Suceava County Hospital. 332 women who underwent colposcopy for cervical lesions between 2006 and 2011 were included in this study. The overall prevalence of HPV was 57.23%. HPV prevalence differs significantly in the three age groups up to 50 years. It was highest in patients below the age of 40 and progressively lower with advancing age. The overall prevalence of cervical dysplasia was 56.62%. The prevalence of cervical dysplasia was highest in the age groups up to 40 years. The most important determinant of HPV infection is age. Persistence of HPV appears to be associated with progression to squamous intraepithelial lesion. Dysplasia is often missed in a cervical sample either because of human error in screening and interpretation, or because of suboptimal quality of Pap smear. Incorporation of HPV testing into the present Pap screening program has the potential of making screening for cervical cancer more effective, and a necessary prelude to assessing this is by determining the prevalence of the high-risk types.

    2014-11-01

    Cervical chondrocutaneous branchial remnants are congenital, benign and rare neck masses. These anomalies are limited in the literature, reported mostly as case reports. Cervical chondrocutaneous branchial remnant is always present at birth, and the lesion is usually unilateral. Understanding and treatment of cervical chondrocutaneous branchial remnants requires knowledge of the related embryology. From January 2005 to December 2008, 17 patients with mean age of 32 months (range from 2 months to 15 years) with CCBRs were treated at the Division of Pediatric Surgery, Department of Plastic and Reconstructive Surgery and Burns at the Institute for Mother and Child Health Care, Belgrade, Serbia. The following objections were recorded: sex, lesion side, surgical data, associated malformations and pathohistology findings. There were 7 females and 10 males, 4 with bilateral presences. Five children had associated anomalies, as follows: vesicoureteral reflux, atrial and ventricular septal defect, ventricular septal defect, branchiootorenal syndrome and preauricular sinus. There was a positive family history in one patient. Fifteen patients (88%) were treated with complete surgical excision and no connections with deep underlying structures of the neck were found. There were no complications at surgery. No recurrence was found during follow-up. Histopathology analysis revealed both, hyaline and elastic cartilage. Cervical chondrocutaneous branchial remnants are rare anomalies arising from branchial arch, probably originally from remnants of first or second arch. Surgical excision is the treatment of choice. From our experience, we suggest surgical treatment early in childhood because of esthetic reason, simplicity of the intervention and low complication rate. Also, the abdominal ultrasound and cardiac examination is recommended because of associated anomalies. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

  7. Abfraction lesions reviewed: current concepts

    Adriana de Fátima Vasconcelos Pereira

    2008-01-01

    Full Text Available Non-carious cervical lesions are characterized by structural loss near the cementoenamel junction, without the presence of caries. Anumber of theories have arisen to explain the etiology of such lesions, although the real causes remain obscure, as is reflected by the contradictory terminology used in the literature. In addition to describing acidic and abrasive processes documented as etiological factors, attention is given to the role of mechanical stress from occlusal load, which is the most accepted theory for the development of abfraction lesions. Considering that tensile stress leads to the failure of restorations in the cervical region and that this is a fruitful area for future research, the present study has highlighted diagnosis, prognosis and the criteria for treatment.

  8. Effect of Cervical Lessions on the Tooth FEM Study

    Full Text Available The approach used until recently concerning the phenomena of dental abfraction points to the conclusion that the cervical area of the tooth, were this type of lesion usually occur, concentrates the stress resulted from the action of the forces applied on various areas on the crown. Moreover, any lesion in the cervical area facilitates the possibility of its advance into the tooth, ultimately fracturing it. Our paper presents a FEM (finite element method study on the results of a mechanical analysis of the phenomena involving the tooth damaged by cervical lesions.

  10. Metastatic adenocarcinoma of the cervix presenting as a choroidal mass: A case report and review of literature of cervical metastases to the eye

    Akshay Gopinathan Nair

    2015-01-01

    Full Text Available Cervical cancer is the most common cancer among females in India. Cervical cancer usually spreads by local extension and through the lymphatic drainage to the lymph nodes. Hematogenous spread, the mechanism responsible for distant metastases, is rarely seen in cervical malignancies. In this communication, we report a case of a 45-year-old woman who presented with unilateral decrease in vision of 3 months duration. She was found to have a serous retinal detachment with underlying diffuse, subretinal yellowish-cream colored infiltrates in the right eye, suspicious of choroidal metastases. Systemic evaluation showed disseminated systemic metastases arising from a primary adenocarcinoma of the cervix. In this communication, we review all the documented cases of metastases to the eye and adnexa arising from cervical cancer and their clinical characteristics. Unilateral choroidal metastasis arising from an adenocarcinoma of the cervix is extremely rare with only one previous documented case. Although uncommon, choroidal metastasis may be the presenting feature of primary cervical malignancy. Furthermore, cervical malignancy must be ruled out in women who present with orbital or choroidal metastases arising from unknown primary.

  11. LOW MOLECULAR MASS POLYPEPTIDE AND TRANSPORTER ANTIGEN PEPTIDE GENES POLYMORPHISM AS THE RISK FACTORS OF CERVICAL CANCER WHICH CAUSED BY HUMAN PAPILLOMAVIRUS TYPE-16 INFECTION IN BALI

    I N. B. Mahendra

    2015-12-01

    Full Text Available Background: Until recently, cervical cancer is one of the major problem in women’s health issue related to its high incidence and mortality rate. The etiology of cervical cancer is the high risk oncogenic group of Human Papillomavirus (HPV, especially HPV-16 and 18 and its phylogenies. Meanwhile in Bali, more than 50% of infection are caused by HPV-16 infection. The main objective of this study was to investigate the role of LMP-2, LMP-7, TAP-1 and TAP-2 gene polymorphism as the risk factor in the cervical cancer carcinogenesis that is caused by HPV-16 infection. Method: A nested non-paired case-control study was conducted at Obstetric and Gynecologic Department Sanglah General Hospital, Bali-Indonesia from March 1 until August 31, 2013. Laboratory testing was carried out at Laboratory of Histopathology Leiden University Medical Centre, Netherlands,. Results: A total of 40 samples were collected, consist of 20epithelial cervical cancer patients with positive HPV-16 infection as the case group and 20 non-cervical cancer patients with positive HPV-16 infection as the control group. Women infected by HPV-16 with LMP-7 gene polymorphism had a higher risk (OR=7.36, CI 95%=1.38-40.55, p=0.013 to be diagnosed with cervical cancer. Balinese women who were infected by HPV-16 with TAP-2 gene polymorphism had a higher risk (OR= 9.33, CI 95%=2.18-39.96, p=0.001 to be diagnosed with cervical cancer. Meanwhile, Balinese women who were infected by HPV-16 with LMP-7 and TAP-2 genes polymorphism had a higher risk (OR=12.67, CI 95%=1.40-114.42, p=0.020 to be diagnosed with cervical cancer. As the result, it was shown that both of this gene polymorphism was working synergistically. Conclusion: TAP-2 and LMP-7 genes polymorphism play a role in the carcinogenesis mechanism of cervical cancer that is caused by HPV-16 infection in Bali. Meanwhile, LMP-2 and TAP-1 genes polymorphism were not found to play a role in the immunology pathway of cervical cancer that is

    Figueroa, Reinaldo; Crowell, Rebecca; Martinez, Alvin; Morgan, Marielle; Wakefield, Dorothy

    2018-04-30

    To compare obstetrical outcomes on women undergoing a McDonald or Shirodkar cerclage and to estimate the impact of maternal body mass index (BMI) on these outcomes. We conducted a retrospective review of the medical records of all women with singleton pregnancies who underwent placement of a McDonald or Shirodkar cerclage at St. Francis Hospital from January 2008 to October 2013. The subjects were categorized based on BMI groups (normal: less than 25 kg/m 2 , overweight: 25-29 kg/m 2 , obese: 30 kg/m 2 or more). The primary outcome was gestational age at delivery. Statistical analyses included chi-square, Student's t-test, and multivariable regression analysis. Of 95 women, 47 (49.5%) received a Shirodkar, and 48 (50.5%) a McDonald cerclage. 16 women (16.8%) were categorized as normal weight, 35 (36.8%) as overweight, and 44 (46.3%) as obese. Gestational age at delivery differed significantly by group, decreasing with each categorical increase in BMI (normal: 39.0 ± 0.3 weeks; overweight: 36.6 ± 0.7 weeks; obese: 33.0 ± 1.1 weeks; p McDonald cerclage (36.7 ± 0.6 weeks versus 33.9 ± 1.0 weeks; p = .02). However, analysis showed a significant interaction between weight status and gestational age at delivery. Obese women had significantly longer pregnancies when they received a Shirodkar cerclage versus a McDonald cerclage (32.6 ± 1.0 weeks versus 28.8 ± 0.9 weeks; p McDonald: 32.9 ± 0.9 weeks; p = .63). Compared to obese women receiving a McDonald cerclage, obese women receiving a Shirodkar cerclage had significantly longer pregnancies. No significant differences in pregnancy duration were found in normal/overweight women regardless of cerclage technique. Pregnancy duration in obese women receiving a Shirodkar cerclage was similar to the pregnancy duration of normal/overweight women.

    -stage renal disease seem to be at an increased risk of cervical cancer. A higher risk of cervical precancerous lesions was found in patients with some autoimmune diseases; particularly if treated with immunosuppressants. Among behavioral factors weakening the immune system, smoking appeared to strongly...... increase the risk of cervical cancer, while poor diet only moderately increased the risk. It is difficult to determine whether sexually transmitted infections other than human papillomavirus infection are independent risk factors. Identifying those groups of women likely to fail in clearing persistent...

    This paper reports on cervical hyperextension injuries that are common and often show minimal radiographic abnormalities, even with severe or unstable lesions. MR images and clinical records of 14 patients scanned within 4 months of hyperextension cervical injuries were reviewed. Clinical, radiographic, and MR findings were correlated. Nine patients had acceleration hyperextension whiplash injuries, four with acute cervical disk herniations developing radiculopathy after several weeks. Five patients injured by direct frontal head trauma presented with myelopathy and had MR evidence of cord injury, and four had acute disk herniation

    Although early detection of cancer through screening can prevent cancer deaths, a drawback of screening is overdiagnosis. Overdiagnosis has been much debated in breast cancer screening, but less so in cervical cancer screening. We examined the impact of overdiagnosis by comparing two screening programmes in the Netherlands. We estimated overdiagnosis rates by microsimulation for breast cancer screening and cervical cancer screening, using a cohort of women born in 1982 with lifelong follow-up. Overdiagnosis estimates were made analogous to two definitions formed by the UK 2012 breast screening review. Pre-invasive disease was included in both definitions. Screening prevented 921 cervical cancers (-55%) and 378 cervical cancer deaths (-59%), and 169 (-1.3%) breast cancer cases and 970 breast cancer deaths (-21%). The cervical cancer overdiagnosis rate was 74.8% (including pre-invasive disease). Breast cancer overdiagnosis was estimated at 2.5% (including pre-invasive disease). For women of all ages in breast cancer screening, an excess of 207 diagnoses/100,000 women was found, compared with an excess of 3999 diagnoses/100,000 women in cervical cancer screening. For breast cancer, the frequency of overdiagnosis in screening is relatively low, but consequences are evident. For cervical cancer, the frequency of overdiagnosis in screening is high, because of detection of pre-invasive disease, but the consequences per case are relatively small due to less invasive treatment. This illustrates that it is necessary to present overdiagnosis in relation to disease stage and consequences. © The Author(s) 2016.

  19. Human Papillomavirus and Vaccination in Cervical Cancer

    Kung-Liahng Wang

    2007-12-01

    Full Text Available Cervical cancer is not only the most frequently reported cancer among women, but also the most common female genital tract neoplasm in Taiwan. Early detection is effective, because the development, maintenance and progression of precursor lesions (cervical intraepithelial neoplasia [CIN] evolve slowly into invasive cancer, typically over a period of more than 10 years. It is now recognized that human papillomavirus (HPV infection is a necessary cause for over 99% of cervical cancer cases. Advances in the understanding of the causative role of HPV in the etiology of high-grade cervical lesions (CIN 2/3 and cervical cancer have led to the development, evaluation and recommendation of HPV-based technologies for cervical cancer prevention and control. The prevention of HPV infection before the onset of CIN is now possible with recently available prophylactic HPV vaccines, e.g. the quadrivalent Gardasil (Merck & Co., NJ, USA and bivalent Cervarix (GlaxoSmithKline, London, UK. This review article provides an up-to-date summary of recent studies and available information concerning HPV and vaccination in cervical cancer.

    Sciatica-like leg pain can be the main presenting symptom in patients with cervical cord compression. It is a false localizing presentation, which may lead to missed or delayed diagnosis, resulting in the wrong plan of management, especially in the presence of concurrent lumbar lesions. Medical history, physical findings and the results of imaging studies were reviewed in two cases of cervical cord compressions, which presented with sciatica-like leg pain. There was multi-level cervical spond...

    2008-01-01

    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.

  9. Mass

    Quigg, Chris

    2007-01-01

    In the classical physics we inherited from Isaac Newton, mass does not arise, it simply is. The mass of a classical object is the sum of the masses of its parts. Albert Einstein showed that the mass of a body is a measure of its energy content, inviting us to consider the origins of mass. The protons we accelerate at Fermilab are prime examples of Einsteinian matter: nearly all of their mass arises from stored energy. Missing mass led to the discovery of the noble gases, and a new form of missing mass leads us to the notion of dark matter. Starting with a brief guided tour of the meanings of mass, the colloquium will explore the multiple origins of mass. We will see how far we have come toward understanding mass, and survey the issues that guide our research today.

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

    Ellison, G. W.; Seim, III, H. B.; Clemmons, R. M.

    1988-08-15

    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.

  15. Cervical Spondylosis and Hypertension

    Peng, Baogan; Pang, Xiaodong; Li, Duanming; Yang, Hong

    2015-01-01

    Abstract Cervical spondylosis and hypertension are all common diseases, but the relationship between them has never been studied. Patients with cervical spondylosis are often accompanied with vertigo. Anterior cervical discectomy and fusion is an effective method of treatment for cervical spondylosis with cervical vertigo that is unresponsive to conservative therapy. We report 2 patients of cervical spondylosis with concomitant cervical vertigo and hypertension who were treated successfully with anterior cervical discectomy and fusion. Stimulation of sympathetic nerve fibers in pathologically degenerative disc could produce sympathetic excitation, and induce a sympathetic reflex to cause cervical vertigo and hypertension. In addition, chronic neck pain could contribute to hypertension development through sympathetic arousal and failure of normal homeostatic pain regulatory mechanisms. Cervical spondylosis may be one of the causes of secondary hypertension. Early treatment for resolution of symptoms of cervical spondylosis may have a beneficial impact on cardiovascular disease risk in patients with cervical spondylosis. PMID:25761188

  16. Automated image analysis of uterine cervical images

    Li, Wenjing; Gu, Jia; Ferris, Daron; Poirson, Allen

    2007-03-01

    Cervical Cancer is the second most common cancer among women worldwide and the leading cause of cancer mortality of women in developing countries. If detected early and treated adequately, cervical cancer can be virtually prevented. Cervical precursor lesions and invasive cancer exhibit certain morphologic features that can be identified during a visual inspection exam. Digital imaging technologies allow us to assist the physician with a Computer-Aided Diagnosis (CAD) system. In colposcopy, epithelium that turns white after application of acetic acid is called acetowhite epithelium. Acetowhite epithelium is one of the major diagnostic features observed in detecting cancer and pre-cancerous regions. Automatic extraction of acetowhite regions from cervical images has been a challenging task due to specular reflection, various illumination conditions, and most importantly, large intra-patient variation. This paper presents a multi-step acetowhite region detection system to analyze the acetowhite lesions in cervical images automatically. First, the system calibrates the color of the cervical images to be independent of screening devices. Second, the anatomy of the uterine cervix is analyzed in terms of cervix region, external os region, columnar region, and squamous region. Third, the squamous region is further analyzed and subregions based on three levels of acetowhite are identified. The extracted acetowhite regions are accompanied by color scores to indicate the different levels of acetowhite. The system has been evaluated by 40 human subjects' data and demonstrates high correlation with experts' annotations.

  17. Drip, ship, and grip, then slice and dice: Comprehensive stroke center management of cervical and intracranial emboli.

    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.

  19. Influence of region of interest size and ultrasound lesion size on the performance of 2D shear wave elastography (SWE) in solid breast masses

    Skerl, K.; Vinnicombe, S.; Giannotti, E.; Thomson, K.; Evans, A.

    2015-01-01

    Aim: To evaluate the influence of the region of interest (ROI) size and lesion diameter on the diagnostic performance of 2D shear wave elastography (SWE) of solid breast lesions. Materials and methods: A study group of 206 consecutive patients (age range 21–92 years) with 210 solid breast lesions (70 benign, 140 malignant) who underwent core biopsy or surgical excision was evaluated. Lesions were divided into small (diameter <15 mm, n=112) and large lesions (diameter ≥15 mm, n=98). An ROI with a diameter of 1, 2, and 3 mm was positioned over the stiffest part of the lesion. The maximum elasticity (E_m_a_x), mean elasticity (E_m_e_a_n) and standard deviation (SD) for each ROI size were compared to the pathological outcome. Statistical analysis was undertaken using the chi-square test and receiver operating characteristic (ROC) analysis. Results: The ROI size used has a significant impact on the performance of E_m_e_a_n and SD but not on E_m_a_x. Youden's indices show a correlation with the ROI size and lesion size: generally, the benign/malignant threshold is lower with increasing ROI size but higher with increasing lesion size. Conclusions: No single SWE parameter has superior performance. Lesion size and ROI size influence diagnostic performance. - Highlights: • Optimal cut-off for benign/malignant differentiation depends on lesion size. • Region of interest size influences measurements of mean elasticity and standard deviation. • Large lesions are stiffer than small lesions. • Optimal cut-off for benign/malignant differentiation should increase with increasing lesion size. • Region of interest of 2 mm achieved best compromise of the diagnostic performance for all SWE parameter.

    2017-07-15

    The superiority of endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) over EUS-guided fine needle aspiration (EUS-FNA) remains controversial. Given the lack of studies analyzing histologic specimens acquired from EUS-FNB or EUS-FNA, we compared the proportion of the histologic core obtained from both techniques. A total of 58 consecutive patients with solid mass lesions were enrolled and randomly assigned to the EUS-FNA or EUS-FNB groups. The opposite needle was used after the failure of core tissue acquisition using the initial needle with up to three passes. Using computerized analyses of the scanned histologic slide, the overall area and the area of the histologic core portion in specimens obtained by the two techniques were compared. No significant differences were identified between the two groups with respect to demographic and clinical characteristics. Fewer needle passes were required to obtain core specimens in the FNB group (pcore (11.8%±19.5% vs 8.0%±11.1%, p=0.376) or in the diagnostic accuracy (80.6% vs 81.5%, p=0.935) between two groups. The proportion of histologic core and the diagnostic accuracy were comparable between the FNB and FNA groups. However, fewer needle passes were required to establish an accurate diagnosis in EUS-FNB.

  1. Cervical spinal cord injuries in patients with cervical spondylosis.

    Regenbogen, V S; Rogers, L F; Atlas, S W; Kim, K S

    1986-02-01

    Eighty-eight patients over age 40 with traumatic cervical spinal cord injuries were clinically and radiographically evaluated, and comparison was made with 35 spinal cord injury patients under age 36. While most older patients sustained obvious bony and/or ligamentous damage commensurate with their neurologic findings, 25 (28%) of the 88 patients had no demonstrable bony abnormalities and 17 (20%) of the 88 patients had only minimal evidence of bony injury. Of particular interest are the patients with severe cord injuries, yet no bony abnormalities, who seem to form a distinct subgroup of the cervical spinal cord injury patient on the basis of radiographic and clinical features. Of these 25 patients, 24 (96%) had severe cervical spondylosis. Fourteen (56%) of the 25 patients were injured in falls, five (36%) of these 14 being of a seemingly trivial nature. Of the 42 patients with minimal or no demonstrable bony abnormalities, 33 (79%) were evaluated with plain tomography and no occult fractures or other significant pathology was demonstrated. Pantopaque myelography in 27 (64%) of the 42 cases revealed no extruded disk or other surgical lesion in any patient. In large measure, these injuries can be attributed to cervical spondylosis, which narrows the canal and makes the cord more susceptible to compression by the bulging ligamenta flava during hyperextension.

  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.

Knowing the influence of age and the etiological agents for sexually transmitted diseases on the risk of developing low and high grade intraepithelial lesions. METHODS: Cross sectional prevalence study at a public referral center for cervical cancer. We studied records of 253 women with atypical diagnoses of undetermined significance, in 2007. RESULTS: The prevalence of intraepithelial lesions was 23.7%; 26.7% were low grade and 73.3% high grade. CONCLUSIONS: The prevalence of high-grade intraepithelial lesions in women with Pap smear diagnosis of atypical squamous cells of undetermined significance (ASCUS was 23.7%; the increase in risk was directly proportional to the age and higher prevalence of low grade squamous intraepithelial lesion associated with papillomavirus infection.

  7. Resolution of a periodontoid rheumatoid pannus mass in an elderly patient treated with a rigid cervical collar: A case report and literature review.

    Oseni, Abidemi; Kakavas, Georg; Scholz, Martin; Petridis, Athanasios

    2016-06-17

    In patients with C2 rheumatoid pannus with spinal cord compression the treatment of choice is extensive surgery either through a transoral resection of the dens axis or a dorsal stabilisation, or both. We present a case of an 11-mm rheumatoid pannus with significant compression of the spinal cord, which failed surgical treatment with respect to dorsal stabilisation. Therefore, rigid cervical collar for 8 weeks followed by soft collar for another 4 weeks was chosen as a treatment option. During the follow-up period of 1 year, the pannus reduced significantly and the spinal cord decompressed. In cases where surgery is not an option or is technically very demanding, the alternative of cervical collar immobilisation is a satisfying option.

    A 34-year-old woman complained of right hemiparesis and pain in the right hand. Routine X-ray of the cervical portion failed to reveal abnormal findings. CT with intravenous contrast medium showed a large high-density mass in the spinal canal at the level of C2. Right vertebral angiography showed a hypervascular mass. With simultaneous intravenous and intrathecal injections of contrast medium, the tumor was shown as a moderately high-density area and the parenchyma of cord as a thin low-density area surrounding the tumor stain on CT. These CT appearances led to the final diagnosis of high cervical intramedullary hemangioblastoma associated with arteriovenous fistulae. Pathological findings are typical of hemangioblastoma. The usefulness of CT in detecting the localization of hypervascular spinal cord lesions is stressed. (Namekawa, K.).

    Full Text Available Background Dysphagia, is a significant sign of many different lesions in upper digestive system especially in proximal esophagus. Tumors, gastroesophageal reflux, achalasia and extrinsic compressions are the most common causes that may lead to dysphagia in geriatric population. Cervical osteophyte induced dysphagia, is one of the uncommon reasons of dysphagia, therefore other causes of dysphagia must be excluded to establish the exact diagnosis. Eagle syndrome is one of the considerable reason which may lead to misdiagnosis in patients with cervical osteophytes. In this case report, we represent four patients who had dysphagia due to anteriorly located cervical osteophytes and evaluate the patients with special reference to Eagle syndrome. Material and methods After a detailed anamnesis and ENT examination, cervical plain radiographs in four projections and Towne radiographs were obtained for every patient. After that, magnetic resonance imaging (MRI of cervical spine and barium swallowing studies were performed to evaluate the presence of esophageal compression. Results Eagle syndrome was excluded due to absence of other symptoms and physical signs, eventhough unilateral or bilateral elongation of styloid processes was found in all of the patients. Conclusion Cervical osteophytes induced dysphagia is a rare clinical entity, diagnosis should be done by a careful examination, intensive radiologic evaluation. Moreover, all the other causes like Eagle syndrome should be excluded during the diagnosis of cervical osteophyte induced dysphagia.

    To evaluate the influence of the region of interest (ROI) size and lesion diameter on the diagnostic performance of 2D shear wave elastography (SWE) of solid breast lesions. A study group of 206 consecutive patients (age range 21-92 years) with 210 solid breast lesions (70 benign, 140 malignant) who underwent core biopsy or surgical excision was evaluated. Lesions were divided into small (diameter <15 mm, n=112) and large lesions (diameter ≥15 mm, n=98). An ROI with a diameter of 1, 2, and 3 mm was positioned over the stiffest part of the lesion. The maximum elasticity (Emax), mean elasticity (Emean) and standard deviation (SD) for each ROI size were compared to the pathological outcome. Statistical analysis was undertaken using the chi-square test and receiver operating characteristic (ROC) analysis. The ROI size used has a significant impact on the performance of Emean and SD but not on Emax. Youden's indices show a correlation with the ROI size and lesion size: generally, the benign/malignant threshold is lower with increasing ROI size but higher with increasing lesion size. No single SWE parameter has superior performance. Lesion size and ROI size influence diagnostic performance. Copyright © 2015. Published by Elsevier Ltd.

    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.

  12. Intraosseous osteolytic lesions

    1981-10-01

    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.

    2003-01-01

    Cervical chondrocutaneous branchial remnants are rare and not well known lesions. Histologically the lesion per definition presents as a Choristoma. Choristoma is the pathohistological term for a developmental tumor-like anomaly consisting of tissues foreign to the site at which it is located. Treatment is complete surgical removal as promptly as possible in order to get an exact histopathological diagnosis. A case of a 4-month-old boy with cervical chondrocutaneous branchial remnants anterior to the sternocleidomastoid muscles on both sides is presented. According to literature search this appears to be the second case published on such a bilateral lesion.

    To explore the feasibility and the result for the surgical treatment of spastic cerebral paralysis of the upper limbs in patients who underwent the selective cervical dorsal root cutting off part of the vertebral lateral mass fixation combined with exercise therapy. From March 2004 to April 2008, 27 patients included 19 boys and 8 girls, aging 13-21 years with an average of 15 years underwent selective cervical dorsal root cutting off part of the vertebral lateral mass fixation with exercise therapy. The AXIS 8 holes titanium plate was inserted into the lateral mass of spinous process through guidance of the nerve stimulator, choosed fasciculus of low-threshold nerve dorsal root and cut off its 1.5 cm. After two weeks, training exercise therapy was done in patients. Training will include lying position, turning body, sitting position, crawling, kneeling and standing position, walking and so on. Spastic Bobath inhibiting abnormal pattern was done in the whole process of training. The muscular tension, motor function (GMFM), functional independence (WeeFIM) were observed after treatment. All patients were followed up from 4 to 16 months with an average of 6 months. Muscular tension score were respectively 3.30 +/- 0.47 and 1.25 +/- 0.44 before and after treatment;GMFM score were respectively 107.82 +/- 55.17 and 131.28 +/- 46.45; WeeFIM score were respectively 57.61 +/- 25.51 and 87.91 +/- 22.39. There was significant improvement before and after treatment (P cerebral paralysis of the upper limbs is safe and effective method, which can decrease muscular tension and improve motor function, which deserves more wide use.

    MINI: A 3D printing technology is proposed for reconstructing multilevel cervical spine (C2-C4) after resection of metastatic papillary thyroid carcinoma. The personalized porous implant printed in Ti6AL4V provided excellent physicochemical properties and biological performance, including biocompatibility, osteogenic activity, and bone ingrowth effect. A unique case report. A three-dimensional (3D) printing technology is proposed for reconstructing multilevel cervical spine (C2-C4) after resection of metastatic papillary thyroid carcinoma in a middle-age female patient. Papillary thyroid carcinoma is a malignant neoplasm with a relatively favorable prognosis. A metastatic lesion in multilevel cervical spine (C2-C4) destroys neurological functions and causes local instability. Radical excision of the metastasis and reconstruction of the cervical vertebrae sequence conforms with therapeutic principles, whereas the special-shaped multilevel upper-cervical spine requires personalized implants. 3D printing is an additive manufacturing technology that produces personalized products by accurately layering material under digital model control via a computer. Reporting of this recent technology for reconstructing multilevel cervical spine (C2-C4) is rare in the literature. Anterior-posterior surgery was performed in one stage. Radical resection of the metastatic lesion (C2-C4) and thyroid gland, along with insertion of a personalized implant manufactured by 3D printing technology, were performed to rebuild the cervical spine sequences. The porous implant was printed in Ti6AL4V with perfect physicochemical properties and biological performance, such as biocompatibility and osteogenic activity. Finally, lateral mass screw fixation was performed via a posterior approach. Patient neurological function gradually improved after the surgery. The patient received 11/17 on the Japanese Orthopedic Association scale and ambulated with a personalized skull-neck-thorax orthosis on

  18. Radiobiological characteristics of cervical cancer

    Kagabu, Teruo; Kobayashi, Takashi; Nanayama, Kunihiko

    1976-01-01

    In order to observe the radiobiological characteristics of cervical cancer, the author carried out irradiation of 60 Co in 16 cases of cervical cancer. The primary lesion of each case was exposed to radiation of 100 R once a day, 40 times in sequence, totaling 4,000 R. To evaluate this results, the vaginal smears were obtained everyday and examined for changes in cancerous cells caused by the irradiation. The results of our study showed that cervical cancer could be classified into three groups according to the radiosensitivity of its cancerous cells. In the group of low-radiosensitivity (11 cases of 16), the cancerous cells decreased gradually, and enlargement of the nuclei of the cancerous cells was observed from 2,000 R of irradiation, but the majority of the cancerous cells were those of nucleus after the irradiation of 4,000 R. In all of the 5 uterus removed, residual cancer lesion was noted. The radiocuability was unfavourable. In the group of high-radiosensitivity (4 cases of 16), the cancerous cells decreased remarkablly. Enlargement of nucleus was noted from 1,000 R of the irradiation, the cancerous cells of small-sized nucleus appeared with the irradiation of 3,000 R but the cancerous cells almost disappeared with the irradiation of 4,000 R. The radiocuability was favourable. In the group of combination of high-radiosensitivity and low-radiosensitivity portions (one case of 16), the cancerous cells decreased remarkablly until the exposure to the radiation of 2,000 R but thereafter did slowly. In a removed uterus, the cancer lesion was noted, but the prognosis was favourable. The foregoing results suggest that changes in the nuclear diameter of the cancerous cells in vaginal smears during irradiation can tell the radiosensitivity of the cancerous cells. (Kanao, N.)

    2010-01-01

    Hematoma of the cervical ligamentum flavum is very rare, and its pathogenesis is unknown. We describe a case of ligamentum flavum hematoma in the cervical spine causing severe myelopathy. Postoperative histological examination suggested it was the result of the rupture of a hemangioma or of an arteriovenous malformation in the ligamentum flavum. After removal of the lesion, the patient's condition immediately improved. Review of all three reported cases, including this one, showed that complete resection of the mass resulted in immediate relief of symptoms of incomplete paraplegia. The findings of magnetic resonance imaging (MRI) of the hematoma may vary with time, and they may show no characteristic intensity. However, MRI of this case revealed that the tissues surrounding the mass were enhanced with gadolinium diethylene triamine penta-acetic acid, and an area of homogeneous iso-intensity was clearly surrounded by a low-intensity area (flavum) on T2-weighed short-tau inversion recovery images. These findings could be characteristic of the ligamentum flavum hematoma and might help in the differentiation from a cervical epidural hematoma. (orig.)

    Full Text Available Early detection of precancerous cells in the cervix and their clinical management is the main purpose of cervical cancer prevention and treatment programs. Cytological findings or testing for high risk (HR-human papillomavirus (HPV are inadequately sensitive for use in triage of women at high risk for cervical cancer. The current study is an exploratory study to identify candidate surface-enhanced laser desorption/ionization (SELDI time of flight (TOF mass spectrometry (MS protein profiles in plasma that may distinguish cervical intraepithelial neoplasia (CIN 3 from CIN 1 among women infected with HR-HPV. We evaluated the SELDI-TOF-MS plasma protein profiles of HR-HPV positive 32 women with CIN 3 (cases and 28 women with CIN1 (controls. Case-control status was kept blinded and triplicates of each sample and quality control plasma samples were randomized and after robotic sample preparations were run on WCX2 chips. After alignment of mass/charge (m-z values, an iterative method was used to develop a classifier on a training data set that had 28 cases and 22 controls. The classifier developed was used to classify the subjects in a test data set that has six cases and six controls. The classifier separated the cases from controls in the test set with 100% sensitivity and 100% specificity suggesting the possibility of using plasma SELDI protein profiles to identify women who are likely to have CIN 3 lesions.

    Noh, Sang-Mi; Kang, Hyun Goo

    2018-07-01

    Occipital neuralgia is a common form of headache that is characterized by paroxysmal severe lancinating pain in the occipital nerve distribution. The exact pathophysiology is still not fully understood and occipital neuralgia often develops spontaneously. There are no specific guidelines for evaluation of patients with occipital neuralgia. Cervical spine, spinal cord and posterior neck muscle lesions can induce occipital neuralgia. Brain and spine imaging may be necessary in some cases, according to the nature of the headache or response to treatment. We report a case of cervical myelitis presenting as occipital neuralgia.

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

    Brophy, Carl M; Hoh, Daniel J

    2018-06-01

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

  8. Trends in the incidence of benign pathological lesions at partial nephrectomy for presumed renal cell carcinoma in renal masses on preoperative computed tomography imaging. A single institute experience with 290 consecutive patients

    2010-06-15

    The aim of this study was to determine trends in the incidence of benign lesions in patients undergoing surgery for suspicious renal masses on preoperative computed tomography scan. The records of 1065 patients who underwent open consecutive partial nephrectomy (PN) or radical nephrectomy (RN) between January 2001 and December 2008 were reviewed. Patients who underwent PN during the periods 2001-2002, 2003-2004, 2005-2006, and 2007-2008 were assigned to groups 1, 2, 3 and 4, respectively. The frequencies of benign and malignant lesions in these groups were assessed according to size and histology subtypes. The ratio of PN to RN was 12.4%, 18.3%, 24.3% and 37.2% in groups 1, 2, 3 and 4, respectively (P<0.05). The mean size of resected lesions was 2.6 cm (range 0.8-6.2 cm). Of the 290 cases, histopathology revealed benign findings in 52 (17.9%). Benign pathology was found in three of 18 cases (16.7%) in group 1, seven of 36 cases (19.4%) in group 2, 12 of 63 cases (19.0%) in group 3 and 30 of 173 cases (17.3%) in group 4. There was no significant difference in the frequency of benign histology among groups. PN, as opposed to RN, has shown a rising tendency over time. The frequency of benign pathology findings after PN for suspicious renal masses on preoperative computed tomography imaging has not decreased. Proper management should favor nephron-sparing surgery for renal lesions if such lesions can be removed satisfactorily with PN. (author)

    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.

    2012-01-01

    Full Text Available Introduction: Since the pioneering days of the anterior cervical approach introduced by Cloward et al. in the early 1950s, anterior cervical discectomy and fusion (ACDF has been the standard procedure for most discogenic and degenerative cervical spinal lesions. Although traditional interbody fusion using iliac bone can maintain the patency of the neuroforamen and ensure solid fusion, selection of patients, and of surgical procedure for ACDF is a continuous challenge. Aim: The aim of this study was to assess the results of cervical discectomy and fusion with cervical cages in treatment of cervical radiculopathy clinically and radiologically. Materials and Methods: Eighteen patients suffering from cervical radiculopathy were operated upon using this technique. They were 15 males and 3 females. Clinical and radiological assessment, visual analog scale (VAS for neck and arm and modified Oswestery neck disability index (NDI were done preoperatively and at 4 weeks, 3, 6, and 12 months postoperatively. Polyetheretherketone (Peek cages filled with iliac bone graft were used after cervical discectomy. The levels operated upon were C 5-6 in 16 patients and C4-5 in 2 patients. Results: Marked clinical improvement as regard arm and neck pain, and NDI was observed. The pre and post operative mean and standard deviations (SD of the various scores were as follows. VAS for pain in arm reduced from mean of 8 (SD 1.76 to mean 0.4 (SD 0.4, VAS for neck pain reduced from mean of 3.5 (SD 1.58 to mean of 0.8 (SD 0.47, and NDI from mean of 20.2 (SD 0.89 to 2.1(SD 1.05. Fusion occurred in all patients. Subjectively 79% of the patients reported marked improvement in neck pain, and 95% reported marked reduction in arm pain. Conclusion: Anterior cervical discectomy and cage fusion resulted in high fusion rate with minimal preservation of lordosis.

  5. Management of common head and neck masses.

    Tracy, Thomas F; Muratore, Christopher S

    2007-02-01

    Head and neck masses are a common clinical concern in infants, children, and adolescents. The differential diagnosis for a head or neck mass includes congenital, inflammatory, and neoplastic lesions. An orderly and thorough examination of the head and neck with an appropriate directed workup will facilitate the diagnosis. The most common entities occur repeatedly within the various age groups and can be differentiated with a clear understanding of embryology and anatomy of the region, and an understanding of the natural history of a specific lesion. Congenital lesions most commonly found in the pediatric population include the thyroglossal duct cyst and the branchial cleft and arch anomalies. The inflammatory masses are secondary to local or systemic infections. The most common etiology for cervical adenopathy in children is reactive lymphadenopathy following a viral or bacterial illness. Persistent adenopathy raises more concerns, especially enlarged lymph nodes within the posterior triangle or supraclavicular space, nodes that are painless, firm, and not mobile, or a single dominant node that persists for more than 6 weeks should all heighten concern for malignancy. In this review, we discuss the current principles of surgical management of the most common head and neck masses that present to pediatricians and pediatric surgeons.

    Identification of high-risk HPV genotypes in patients is essential for vaccination and prevention programs while the geographic distribution of cervical cancer varies widely. HPV 16 is the major cause of cervical cancer followed by HPV 18, HPV 31, HPV 52, or HPV 58 depending on geographic area. In this study, the distribution of HPV genotypes in cervical specimens from women living in Thailand was analyzed by HPV testing with electrochemical DNA chip and PCR direct sequencing. The 716 specimens were grouped according to their cytological grades; 100 normal, 100 low-grade squamous intraepithelial lesions, 100 high grade squamous intraepithelial lesions, and 416 specimens of cervical cancer. The results showed that HPV 16, HPV 18, HPV 52, and HPV 58 are the most common HPV genotypes in Thailand, respectively. With respect to age, women below the age of 26 years were almost negative for high-risk HPV DNA exclusively. Conversely, high prevalence of high-risk HPV DNA and abnormal cytology were usually found in women between 26 and 45 years while cervical cancer was detected mainly in women above the age of 45 years. To increase protection efficiency, a vaccine including HPV 52 and HPV 58 should be offered to Asian women, and primary HPV screening should start at 26-30 years of age. © 2013 Wiley Periodicals, Inc.

  8. Lateral Pectoral Nerve Injury Mimicking Cervical Radiculopathy.

    Aktas, Ilknur; Palamar, Deniz; Akgun, Kenan

    2015-07-01

    The lateral pectoral nerve (LPN) is commonly injured along with the brachial plexus, but its isolated lesions are rare. Here, we present a case of an isolated LPN lesion confused with cervical radiculopathy. A 41-year-old man was admitted to our clinic because of weakness in his right arm. Previous magnetic resonance imaging (MRI) examination revealed right posterolateral protrusion at the C6-7 level. At the initial assessment, atrophy of the right pectoralis major muscle was evident, and mild weakness of the right shoulder adductor, internal rotator, and flexor muscles was observed. Therefore, electrodiagnostic evaluation was performed, and a diagnosis of isolated LPN injury was made. Nerve injury was thought to have been caused by weightlifting exercises and traction injury. Lateral pectoral nerve injury can mimic cervical radiculopathy, and MRI examination alone may lead to misdiagnosis. Repeated physical examinations during the evaluation and treatment phase will identify the muscle atrophy that occurs 1 or more months after the injury.

  9. Fractal analysis of cervical intraepithelial neoplasia.

    Markus Fabrizii

    Full Text Available 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.

    1984-01-01

    Arteriovenous malformation (AVM) of the cervical spinal cord has been known to constitute 5-13% of all spinal AVMs. In contrast to the AVMs located in thoracic or thoraco-lumbar regions, cervical AVM has several characteristic features such as preponderance in younger generation, high incidence of subarachnoid hemorrhage, intramedullary location of the nidus usually fed by the anterior spinal arterial system. We reported three cases of cervical AVMs, which located intramedullary at the levels of C 4 -C 6 , C 1 -C 4 and C 1 -C 2 , respectively. Although selective angiography (vertebral artery, thyrocervical artery, costocervical artery) was essential for the diagnosis of these lesions, computerized tomographic (CT) study with both intrathecal injection of metrizamide and intravenous infusion of contrast material (dynamic and static study) was found to be extremely advantageous in detecting the topography of AVMs in the concerned horizontal planes of the spinal cord. Removal of AVM was given up in one case because of its possible involvement of the anterior spinal artery and central artery shown by CT scan. Removal of AVMs were performed in other two cases. A lateral approach was tried in one case with the AVM located in C 1 -C 2 level, in which CT scan revealed not only an intramedullary but the associated extramedullary AVM in ventrolateral surface of the spinal cord. This operative approach was found to involve less bone removal and markedly reduce spinal cord manipulation necessary to deal with ventrally situated high cervical lesions, compared with a posterior approach with laminectomy.

    Full Text Available Los quistes dermoides presentan una incidencia de 1,6 hasta 6,9 % en la región de cabeza y cuello. Se realiza el siguiente reporte de caso clínico con el objetivo de enfatizar en la importancia de un adecuado manejo diagnóstico preoperatorio, para establecer una acertada planificación quirúrgica en la exéresis de este tipo de lesiones de la región cervicofacial. Se presenta el caso clínico de un paciente masculino, de 13 años de edad, quien hacía 3 años se notaba un crecimiento redondeado en región submentoniana, lo cual le ocasionaba molestias al hablar y ligera afectación de su estética facial. Una vez realizados los estudios complementarios preoperatorios, se decide tratamiento quirúrgico, empleando una cervicotomía medial para la extirpación de la lesión quística, dada la ubicación anatómica por debajo del músculo milohiodeo y su gran dimensión. El diagnóstico histopatológico se corresponde con un quiste epidérmico. Se concluye que resulta imprescindible realizar un exhaustivo examen físico e imagenológico, para lograr resultados satisfactorios en el tratamiento quirúrgico del quiste dermoide cervical.

    Prophylactic human papillomavirus (HPV) vaccine is the most promissory public health tool for primary prevention of cervical cancer. Immunization of females before the acquisition of HPV infection has the greatest impact in preventing pre-neoplasic lesions and cervical cancer. Current HPV vaccines do not eliminate cervical cancer risk, therefore, screening should continue covering vaccinated as well as women that do not get the vaccine. The strategies that include combination of high-coverage...

  16. Bilateral cervical spondylolysis of C7.

    Paik, Nam Chull

    2010-11-01

    Cervical spondylolysis, which is defined as a cleft between the superior and inferior articular facets of the articular pillar, is a rare condition. The sixth cervical vertebra (C6) is the level most commonly affected. Cases involving C2, C3, C4, or C5 have also been reported. However, to date, no case of C7 spondylolysis has been reported. To present a rare case of bilateral spondylolysis of the seventh cervical vertebra (C7) in a 58-year-old man. A case report. A 58-year-old man visited our hospital with chronic posterior neck pain radiating to the left upper extremity. Magnetic resonance imaging (MRI) study revealed left foraminal disc herniations at C5-C6 and C6-C7. Cervical spondylolysis involving C7 was discovered incidentally during computed tomography (CT)-guided transforaminal steroid injection. Plain radiographs, CT images, and MRIs were reviewed thoroughly once again. The patient's symptoms were relieved after he received CT-guided transforaminal steroid injections. Plain radiographs revealed a radiolucent defect in the articular pillar and cleft at the spinous process of C7. Computed tomography confirmed bilateral spondylolysis and spina bifida occulta of the C7 vertebra. Magnetic resonance imaging revealed absence of edema, which was suggestive of a chronic lesion. Involvement of C7 is not exceptional in a case of cervical spondylolysis. Copyright © 2010 Elsevier Inc. All rights reserved.

  17. [Traumatic spinal complications of cervical arthrosis].

    1996-02-17

    Cervical spondylotic myelopathy is usually a chronic and progressive disease. In a few cases, however, dramatic tetraplegia sometimes occurs after even minor injury. We report seven patients (6 males, 1 female, aged from 41 to 63), who suffered from acute myelopathy after an injury. In 5 cases, the injury revealed the cervical spondylotic myelopathy. A hyperextension of the cervical spine was found in 5 cases. The injury was severe in only one case, but there was no bony abnormalities, except arthrosis. The most common cause was a fall. In contrast, severe tetraplegia was found in 4 cases. Spontaneous, but incomplete, recuperation occurred in 4 patients. In all 7 cases, CT scan and MRI showed congenital cervical stenosis associated with cervical spondylosis. The level of disco-osteophytic changes was mainly in C4, C5, C6. On T2-weighted spin-echo image, an increased signal intensity was present in the cord of 3 patients, but was not correlated with the severity of the symptoms, nor with improvement. Surgical treatment was performed in 6 cases: 3 laminectomies, 3 anterior or antero-lateral approaches. Improvement after operative decompression was observed in all but one case, even when the motor or sensory deficit persists for more than one year. Motricity of the inferior limbs improved better than the other deficits, perhaps because of the location of non-reversible lesions in the spinal gray matter. The acute medullary syndrome of cervical spondylotic myelopathy is serious and can cause major handicaps. This complication justifies a preventive surgical attitude when medullar signs are moderate, and cervical imagery shows a spondylotic compression of the cord with congenital stenosis.

  18. Prevalence of anal cytological abnormalities in women with positive cervical cytology.

    The objective of this study was to estimate the prevalence of cytological abnormalities of the anal mucosa in women with positive cervical cytology, but without macroscopic anal lesion. Ultimately we postulated if the anal mucosa may be a reservoir of HPV, which would allow the reinfection of cervix. Forty-nine patients with abnormal cervical cytology were selected for this work. In a period not exceeding one week of collecting cervix cytology, two swab specimens of the anal canal were also collected. Women diagnosed with cervical HSIL by Pap smear were referred for colposcopy with biopsy of the lesions, to confirm the cytologic diagnosis and ablation of the lesion. We demonstrated a high prevalence of anal squamous intraepithelial lesions in patients with cervical squamous intraepithelial lesions (29 of the total of 49 patients = 59.2%). Of the 20 cases of cervical LSIL, 11 (55%) had abnormal anal cytology. Of the 26 cases with cervical HSIL, 16 (61.5%) had abnormal anal cytology. So, there was a discrete higher prevalence of abnormal anal cytology in cases of high-grade cervical squamous lesions (cervical HSIL). These results help to support the hypothesis that the anal mucosa is a reservoir of HPV, which can be a source of re-infection for the cervix. However, there was no significant association between the practice of anal sex and the prevalence of anal cytological abnormalities. These facts are epidemiologically important for future programs for population eradication of cervical lesions related to HPV. Diagn. Cytopathol. 2011;39:323-327. © 2010 Wiley-Liss, Inc.

    2015-04-01

    We assessed the age-related prevalence of high risk human papillomavirus (HR-HPV) genotypes and the genotype-associated risk for high-grade cervical intraepithelial neoplasia (CIN) in a large U.S. screening population. A total of 40,901 women aged ≥25 years were screened with liquid-based cytology and HPV testing in the ATHENA (Addressing the Need for Advanced HPV Diagnostics) trial. Genotyping was performed using the LINEAR ARRAY HPV Genotyping Test. HPV16 was the most prevalent genotype in all age groups, ranging from 3.5% to 0.8% in women aged 25-29 and ≥50 years, respectively. The next most prevalent genotypes were HPV52, HPV31 and HPV18. In the overall population, HPV16 conferred the greatest absolute risk of ≥CIN3 both in women aged 25-29 and ≥30 years (14.2% and 15.1%, respectively) followed by HPV31 (8.0% and 7.9%), HPV52 (6.7% and 4.4%) and HPV18 (2.7% and 9.0%). Similar trends were seen in women with negative cytology. The percent positivity increased markedly with disease progression for HPV16 and HPV18 which were responsible for 45.6% and 8.4% of ≥CIN3, respectively. Of note, HPV 18 was responsible for 50% of adenocarcinoma in situ (AIS) and 50% of invasive cancer cases. HPV16 played a major role in the development of ≥CIN3 irrespective of age, supporting the identification of HPV16 in primary screening for all women. Identification of HPV18 is also warranted, given its significant contribution to AIS and cancer. Identification of non-16/18 genotypes as a pool should provide sufficient information for screening.

  4. Isolated Echinococcosis of cervical region

    Pratima Khare

    2014-01-01

    Full Text Available Echinococcosis, commonly called as hydatid disease, is a parasitic infestation caused by the larva of the genus Echinococcus in human. Isolated occurrence of Echinococcosis without any evidence of visceral disease is very rare. A thorough search of the literature revealed only 11 cases of isolated cervical Echinococcosis. We report here a very rare case of isolated hydatid cyst in a 45-year-old female patient, who presented with swelling in right cervical region about 5 cm below the angle of mandible with no evidence of the disease elsewhere in the body. The case was diagnosed on fine needle aspiration cytology. The diagnosis was further supported by histopathology. We propose that the treating physician should also consider the differential diagnosis of Echinococcosis in the presence of an asymptomatic soft tissue mass, especially when the patient lives in an endemic area.

    To explore the differentially expressed proteins in normal cervix, cervical intraepithelial neoplasia (CIN) and cervical squamous cell carcinoma (CSCC) tissues by differential proteomics technique. Cervical tissues (including normal cervix, CIN and CSCC) were collected in Department of Gynecologic Oncology of Beijing Obstetrics and Gynecology Hospital. Two-dimensional fluorescence difference in gel electrophoresis (2-D DIGE) and DeCyder software were used to detect the differentially expressed proteins. Matrix-assisted laser desorption/ionization-time-of-flight tandem mass spectrometry (MALDI-TOF/TOF MS) was used to identify the differentially expressed proteins. Western blot (WB) and immunohistochemistry (IHC) were performed to validate the expressions of selected proteins among normal cervix, CIN and CSCC. 2-D DIGE images with high resolution and good repeatability were obtained. Forty-six differentially expressed proteins (27 up-regulated and 19 down-regulated) were differentially expressed among the normal cervix, CIN and CSCC. 26 proteins were successfully identified by MALDI-TOF/TOF MS. S100A9 (S100 calcium-binding protein A9) was the most significantly up-regulated protein. Eukaryotic elongation factor 1-alpha-1 (eEF1A1) was the most significantly down-regulated protein. Pyruvate kinase isozymes M2 (PKM2) was both up-regulated and down-regulated. The results of WB showed that with the increase in the severity of cervical lesions, the expression of S100A9 protein was significantly increased among the three groups (P = 0.010). The expression of eEF1A1 was reduced but without significant difference (P = 0.861). The expression of PKM2 was significantly reduced (P = 0.000). IHC showed that protein S100A9 was mainly expressed in the cytoplasm, and its positive expression rate was 20.0 % in normal cervix, 70.0 % in CIN and 100.0 % in CSCC, with a significant difference among them (P = 0.006). eEF1A1 was mainly expressed in the cell plasma, and its

    Full Text Available OBJECTIVE. 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. CONCLUSION. Short-term absolute risk of CIN2/3+ after a normal Pap smear with concurrent HR-HPV infection is low (~1%, suggesting that the HR-HPV test has limited utility in short-term clinical decision-making for women with normal cytology.OBJETIVO.

  7. Cervical Microbiome and Cytokine Profile at Various Stages of Cervical Cancer: A Pilot Study.

    Astride Audirac-Chalifour

    Full Text Available 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.

    Full Text Available A restauração de lesões cervicais não cariosas é um procedimento comum na clínica diária, havendo uma alta incidência de casos de perda da restauração, descoloração marginal e recidiva de cárie. A etiologia desse tipo de lesão é considerada multifatorial. Neste trabalho, avaliou-se a microinfiltração diante das seguintes variáveis: tipo de material utilizado (dois adesivos de quarta geração utilizados em conjunto com duas resinas compostas de tipos diferentes, ©microfillª e híbrida, dois métodos de polimerização dos sistemas adesivos (foto e dual e duas técnicas restauradoras (incremental e do incremento único. Na metodologia deste trabalho, utilizaram-se ciclagem térmica e mecânica, técnica de infiltração com nitrato de prata, cortes seriados e leitura dos resultados através de escala de escores. A microinfiltração foi menor quando se utilizou uma resina composta híbrida comparada à resina ©microfillª. Ao se utilizar o método de polimerização dual do sistema adesivo, a microinfiltração foi menor do que com o método somente fotopolimerizável. A técnica restauradora não exerceu influência sobre o padrão de microinfiltração encontrado nas restaurações de lesões cervicais não cariosasRestoration of noncarious cervical lesions is a usual clinical procedure, and there is a high incidence of restoration loss, marginal discoloration, and recurrent caries. All the factors that play an important role in this process have to be considered when studying this kind of lesion of complex multifactorial etiology.

    risk factors associated with cervical intraepithelial lesion recurrence after LEEP conization. METHODS: nested case-control study in a cohort of 201 patients with cervical intraepithelial lesion, that were submitted to LEEP conization. Average follow-up of these patients was 2 years. Ninety-four HIV-infected women and 107 non-infected were enrolled. Cervical conization was achieved by the Loop Electrosurgical Excision Procedure (LEEP. Evaluated surgical biopsy histopathological characteristics were lesion grade, lesion borders and glandular involvement. After surgery all patients were submitted to a colposcopy and cytological evaluation every six months. Recurrent lesions were defined it confirmed by biopsy after surgery. Cases were patients with and controls patients without recurrence. chi2 test and multivariable analysis by logistic regression were used for group comparisons. Kaplan Meier's method was performed for the survival analyses (log-rank test. RESULTS: 40 patients had lesion recurrence. Initially, significant variables were: partner number, HIV-infection, lesion borders and glandular involvement. The most frequent recurrence occurred when there were simultaneous association between positive margins and glandular involvement as indicator for recurrence risk. After logistic regression analysis the main factors associated with lesion recurrence were: glandular involvement (OR-9.1; 95% CI:13.0- 27.5; HIV-infection (OR-4.6; 95% IC:1.1-6.3; compromised margins (OR-2.6; 95% IC:1.9-11.2. CONCLUSIONS: risk factors associated with cervical intraepitelial lesion recurrence were HIV-infection, glandular involvement and compromised margins.

    The purpose of this study was to evaluate the CT features of second branchial cleft cysts. We retrospectively analyzed the computed tomographic images in nine cases of second branchial cleft cyst which was confirmed pathologically. Emphasis was on localization of the masses to fascial spaces as defined by the deep cervical fasica. In all nine cases, the lesions were located in the submandibular and carotid spaces. Among these cases, six(67%) had simultaneous involvement of the other contiguous spaces, such as anterior and posterior cervical spaces. All cases had round or oval, unilocular, cystic masses with partial or complete rim enhancement. In eight cases(89%), smooth and thin walls were observed. In one case, thick wall and septations were noted. No definite calcifications were noted in all cases. The internal contents of cystic masses showed relatively homogeneous appearance, and CT number ranged from 20 to 35.2 Hounsfield unit(HU)(mean, 28.4HU). CT diagnosis of second branchial cleft cyst would be easily obtained from recognition of frequent simultaneous involvement of the other contiguous spaces, along with a typical location and characteristic morphology.

    Maternidade Santa Brígida de Curitiba, PR, were selected. Those patients were sent to colposcopy under the following criteria: 1 previous abnormal cytopathological exams, 2 Indicative clinical data or, 3 Suspected lesions on gynecological exam. The statistical significance analysis of the results was done using the chi-square test. Sensibility, specificity, positive predictive value (PPV and negative predictive value (NPV were also determined.RESULTS: The patients' mean age was 30.2 (±10.9. Cytopathological capability of identifying lesions was 50% when compared to histology. Its specificity was 77%, the sensibility 41%, the PPV 74%, and the NPV 45%. Colposcopy capability of identifying lesions was 50%. Its sensibility, specificity, PPV and NPV were 96%, 19%, 65% and 75% respectively. The two methods associated were capable of identifying 63% of the lesions.CONCLUSIONS: Cytopathology was a high specificity exam, while colposcopy from those selected patients had a high sensibility. Colposcopy association with cytopathological screening, on those selected patients, significantly raises the diagnostic accuracy of cervical cancer precursor lesions.

    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.

    A cervical cytology biobank (CCB) is an extension of current cytopathology laboratory practice consisting in the systematic storage of Pap smears or liquid-based cytology samples from women participating in cervical cancer screening with the explicit purpose to facilitate future scientific research and quality audit of preventive services. A CCB should use an internationally agreed uniform cytology terminology, be integrated in a national or regional screening registry, and be linked to other registries (histology, cancer, vaccination). Legal and ethical principles concerning personal integrity and data safety must be respected strictly. Biobank-based studies require approval of ethical review boards. A CCB is an almost inexhaustible resource for fundamental and applied biological research. In particular, it can contribute to answering questions on the natural history of HPV infection and HPV-induced lesions and cancers, screening effectiveness, exploration of new biomarkers, and surveillance of the short- and long-term effects of the introduction of HPV vaccination. To understand the limitations of CCB, more studies are needed on the quality of samples in relation to sample type, storage procedures, and duration of storage.

    2010-01-01

    Purpose: To investigate the value of diffusion-weighted MR imaging (DWI) in detection of cervical cancer, and to determine the diagnostic accuracy of apparent diffusion coefficient (ADC) values for evaluating cervical cancer before and after chemoradiotherapy. Materials and methods: Thirty-three patients with cervical squamous carcinoma and 20 patients with other pelvic abnormalities underwent diffusion-weighted imaging (DWI) in addition to routine MR imaging. The ADC values of normal cervical tissue, cervical area before and after chemoradiotherapy were measured and compared. Receiver operating characteristic (ROC) analysis was employed to investigate whether ADC values could help in discrimination among normal cervical tissue, cervical cancer before and after therapy, and to obtain the optimal ADC threshold value. Results: Cervical cancer lesion demonstrated obviously hyperintensity on DWI images. The mean ADC value of cervical carcinoma (1.110 ± 0.175 x 10 -3 mm 2 /s) was significantly lower than that of normal cervical tissue (1.593 ± 0.151 x 10 -3 mm 2 /s) (P -3 mm 2 /s) was significantly higher than that before therapy (1.013 ± 0.094 x 10 -3 mm 2 /s) (P -3 mm 2 /s, between cervical area before and after therapy was 1.255 x 10 -3 mm 2 /s, between normal cervical tissue and cervical area after therapy was 1.525 x 10 -3 mm 2 /s. The sensitivity and specificity were 100% and 84.8%, 95.5% and 100%, 70% and 81.8%, respectively. Conclusion: DWI can be applied for the detection of cervical cancer because of its superior disease contrast with normal tissue. The measurement of the ADC values can be a useful tool to monitor the response to therapy for cervical carcinoma.

    1995-01-01

    The cervical spine was examined with the magnetic resonance imaging (MRI) and the conventional roentgenograms in 95 patients with rheumatoid arthritis. The MRI findings of upper cervical disorders were compared with various values determined in roentgenograms: the atlanto-dental interval (ADI), the space available for the spinal cord (SAC), and the Ranawat and Redlund-Johnell values. In patients with vertical setting (VS), MRI showed medullary compression in all those with abnormal Redlund-Johnell values and Ranawat values of 7 mm or less. In patients with anterior atlanto-axial subluxation, compression of the upper cervical cord was observed in all patients with SAC of 13 mm or less. In subaxial lesion of the cervical spine, MRI was found to be as good as roentgenograms in evaluating plate erosion and disc space narrowing and MRI showed extradural pannus. (author)

    1990-03-02

    The authors analyzed cervical intraepithelial neoplasias (CINs) detected after cryotherapy to determine if recurrence is associated with the same human papillomavirus (HPV) type found in the original lesion. Eight women had detectable HPV DNA in CINs that occurred after ablation of another CIN, and for each patient the HPV type in the pretreatment lesion was different from that in the CIN that appeared after cryotherapy. This compares with 12 women who had HPV detected in two or more CINs present at the same time, 11 of whom had the same HPv type noted. they concluded that although multiple, simultaneous CINs in a woman often contain the same HPV type, recurrent CINs that occur after cryotherapy contain an HPV type different from that present in the pretreatment lesion.

  12. Pathophysiology of cervical myelopathy.

    Baptiste, Darryl C; Fehlings, Michael G

    2006-01-01

    Cervical myelopathy is a group of closely related disorders usually caused by spondylosis or by ossification of the posterior longitudinal ligament and is characterized by compression of the cervical spinal cord or nerve roots by varying degrees and number of levels. The decrease in diameter of the vertebral canal secondary to disc degeneration and osteophytic spurs compresses the spinal cord and nerve roots at one or several levels, producing direct damage and often secondary ischemic changes. Clinicians who treat cervical myelopathy cord injuries should have a basic understanding of the pathophysiology and the processes that are initiated after the spinal cord has been injured. Literature review. Literature review of human cervical myelopathy and clinically relevant animal models to further our understanding of the pathological mechanisms involved. The pathophysiology of cervical myelopathy involves static factors, which result in acquired or developmental stenosis of the cervical canal and dynamic factors, which involve repetitive injury to the cervical cord. These mechanical factors in turn result in direct injury to neurons and glia as well as a secondary cascade of events including ischemia, excitotoxicity, and apoptosis; a pathobiology similar to that occurring in traumatic spinal cord injury. This review summarizes some of the significant pathophysiological processes involved in cervical myelopathy.

    1994-01-01

    We performed this study to assess the value of CT in the differential diagnosis of palpable neck masses in children. We retrospectively reviewed the CT scans of the palpable neck masses in 30 children. The masses were proved histopathologically and classified into cystic, solid, and inflammatory mass and their CT findings were analyzed. Twelve cases were cystic masses, 4 were solid masses, and 14 were inflammatory lesions. Cystic masses included cystic lymphangiomas (n=6), branchial cleft cysts (n=3), thyroglossal duct cysts (n=2), and ranula (n=1). Cystic lymphangiomas showed insinuating appearances into adjacent structures and 4 cases occurred in the posterior cervical space. All branchial cleft cysts were round cystic masses with smooth wall and displaced the submandibular gland anteriorly and the sternocleidomastoid muscle posteriorly. Two thyroglossal duct cysts occurred centrally adjacent to the hyoid bone and 1 ranula in the submental area. Solid masses were juvenile hemangioma, pleomorphic adenoma in submandibular gland, neurilemmoma, and fibromatosis colli. Juvenile hemangioma showed well-enhancing mass with indistinct margin and the other solid masses had well-defined margin with their characteristic location. Inflammatory lesions were abscess (n=4), deep neck infections with lymphadenopathy (n=4), submandibular gland inflammation (n=3), and tuberculous lymphadenitis (n=3) and they showed strand-like enhancement in adjacent subcutaneous tissues. Tuberculous lymphadenitis had multiple lymph node enlargement with internal low attenuation areas and showed less surrounding strand-like enhancement than suppurative lymphadenopathies. Most neck masses in infants and children were of congenital or inflammatory origin. CT is useful for the evaluation of the child presenting with a neck mass, because it can differentiate various forms of neck masses and is able to reveal the relationship of the masses to the adjacent structures with their characteristic location

  16. Cervical screening in HPV-vaccinated populations.

    Canfell, K

    2018-06-01

    Cervical screening with cytology has been the basis for substantial reductions in cervical cancer incidence and mortality in most high-income countries over the last few decades. More recently, there have been two key, parallel developments which have prompted a major re-consideration of cervical screening. The first is the emergence of evidence on the improved sensitivity of human papillomavirus (HPV) DNA testing compared to cytology, and the second is the large-scale deployment of prophylactic vaccination against HPV. A key challenge to be overcome before HPV screening could be introduced into national cervical screening programs was the specificity of an infection, for detection of precancerous lesions. This has been done in three ways: (1) by considering the appropriate age for starting HPV screening (30 years in unvaccinated populations and 25 years in populations with mature vaccination programs and high vaccine uptake) and the appropriate screening interval; (2) via development of clinical HPV tests, which are (by design) not as sensitive to low viral loads; and (3) by introducing effective triaging for HPV-positive women, which further risk-stratifies women before referral for diagnostic evaluation. This review discusses these major developments and describes how the benefits of HPV screening are being optimized in both unvaccinated and vaccinated populations.

    To investigate the early effectiveness of the Discover cervical artificial disc replacement in treating cervical spondylosis. Qualified for the selective standard, 24 patients with cervical spondylosis were treated between March 2010 and March 2011. Of 24 patients, 13 patients underwent anterior cervical decompression and fusion (ACDF) (ACDF group, between March 2010 and September 2010) and 11 patients underwent Discover cervical artificial disc replacement (CADR group, between September 2010 and March 2011). There was no significant difference in gender, age, disease duration, lesions typing, and affected segments between 2 groups (P > 0.05). The operative time, blood loss, and complications were recorded. Japanese Orthopaedic Association (JOA) scores, Neck Disability Index (NDI) scores, and Odom's scores were used to evaluate the postoperative effectiveness. In CADR group, the cervical range of motion (ROM) in all directions, and prosthesis eccentricity were measured before and after operation. Symptoms disappeared and no complication occurred after operation in the patients of 2 groups. The patients were followed up 12 to 18 months (mean, 15.3 months) in ACDF group and 6 to 12 months (mean, 9.6 months) in CADR group. The NDI scores in CADR group were significantly higher than those in ACDF group at 1, 3, and 6 months (P 0.05). According to Odom's score at last follow-up, the results were excellent in 6 cases, good in 4 cases, and fair in 3 cases with an excellent and good rate of 76.92% in ACDF group, and were excellent in 9 cases, good in 1 case, and poor in 1 case with an excellent and good rate of 90.91% in CADR group, showing no significant difference (chi2 = 3.000, P = 0.223). The patients in CADR group had significant limit of cervical joint ROM in flexion and extension and right bending at 1 month (P value (P < 0.05). Meanwhile, ROM in left bending were bigger than that in right bending in replaced segment and upper segment (P < 0.05), and the ROM

    The association between some specific human papilloma virus (HPV) types and cervix cancer is well known. However, the genetic conditions that favor the development of cervical cancer are less well known. To determine the presence of satellite instability (MSI) in preneoplastic and neoplastic lesions of the cervix and correlate these findings with HPV genotypes. Biopsy samples of cervical lesions were studied. Sixteen had low grade lesions, 22 had high grade lesions and 28 had an epidermoid cancer. Viral types were identified with polymerase chain reaction, dot-blot hybridization and restriction fragment length polymorphism. MSI was determined using a panel of eight highly informative microsatellites. Microsatellite instability in at least one locus was observed in 91, 56 and 69% of low grade lesions, high grade lesions and epidermoid carcinomas, respectively. MSI-High grade, MSI-Low grade instability and microsatellite stability were observed in 5, 60 and 46% of samples, respectively. Two of three samples with high grade instability had HPV 52 genotype. Other viral subtypes had frequencies that ranged from 78% to 100%, with the exception of HPV16 that was present in only 53% of samples with low grade instability. Two thirds of biopsy samples from cervical lesions had MSI, mechanism that can be involved in the first stages of cervical carcinogenesis. The low frequency of high grade instability, its association with HPV52 and the low frequency of HPV16 in samples with low grade instability, suggest different coadjutant mechanisms in cervical carcinogenesis.

    Full Text Available OBJETIVO: estimar a validade da inspeção visual após aplicação de ácido acético (IVA no rastreamento das neoplasias intra-epiteliais cervicais (NIC e lesões induzidas por HPV, comparando seu desempenho com o da colpocitologia e da colposcopia. MÉTODOS: estudo de validação de teste diagnóstico realizado em 893 mulheres de 18 a 65 anos, rastreadas simultaneamente com colpocitologia, IVA e colposcopia, em unidade de saúde pública de Recife, PE. A IVA foi realizada por embrocação do colo com ácido acético a 5% e observação a olho nu, com auxílio de foco clínico comum. Considerou-se como positividade o achado de qualquer lesão aceto-branca no colo. O padrão-ouro foi o histopatológico de biópsia cervical, realizado sempre que qualquer um dos três testes resultasse anormal. Foram estimados e comparados os indicadores de validade de cada teste, com os respectivos intervalos de confiança a 95%. A concordância entre os resultados dos testes foi avaliada pelo coeficiente kappa (k. RESULTADOS: das 303 mulheres biopsiadas, o estudo histopatológico foi anormal em 24. Deste total, a IVA foi positiva em 22, conferindo-lhe sensibilidade estimada de 91,7%, especificidade de 68,9%, valor preditivo positivo de 7,5% e valor preditivo negativo de 99,7%. Comparando-se os intervalos de confiança a 95%, a IVA mostrou maior sensibilidade que a colpocitologia, mas com menores especificidade e valor preditivo positivo. Houve fraca concordância entre os resultados da IVA e da colpocitologia (k=0,02 e excelente concordância com os da colposcopia (k=0,93. CONCLUSÃO: a IVA foi muito mais sensível que a colpocitologia no rastreamento das NIC e lesões HPV-induzidas e teve o mesmo desempenho da colposcopia. Sua baixa especificidade foi responsável por um elevado número de resultados falso-positivos.PURPOSE: to estimate the validity of visual inspection of cervical intraepithelial neoplasia (CIN and HPV-induced lesion screening, after acetic

    To estimate the ability to discriminate between benign and malignant adnexal masses of different size using: subjective assessment, two International Ovarian Tumor Analysis (IOTA) logistic regression models (LR1 and LR2), the IOTA simple rules and the risk of malignancy index (RMI). We used a multicenter IOTA database of 2445 patients with at least one adnexal mass, i.e. the database previously used to prospectively validate the diagnostic performance of LR1 and LR2. The masses were categorized into three subgroups according to their largest diameter: small tumors (diameter IOTA simple rules and the RMI were applied to each of the three groups. Sensitivity, specificity, positive and negative likelihood ratio (LR+, LR-), diagnostic odds ratio (DOR) and area under the receiver-operating characteristics curve (AUC) were used to describe diagnostic performance. A moving window technique was applied to estimate the effect of tumor size as a continuous variable on the AUC. The reference standard was the histological diagnosis of the surgically removed adnexal mass. The frequency of invasive malignancy was 10% in small tumors, 19% in medium-sized tumors and 40% in large tumors; 11% of the large tumors were borderline tumors vs 3% and 4%, respectively, of the small and medium-sized tumors. The type of benign histology also differed among the three subgroups. For all methods, sensitivity with regard to malignancy was lowest in small tumors (56-84% vs 67-93% in medium-sized tumors and 74-95% in large tumors) while specificity was lowest in large tumors (60-87%vs 83-95% in medium-sized tumors and 83-96% in small tumors ). The DOR and the AUC value were highest in medium-sized tumors and the AUC was largest in tumors with a largest diameter of 7-11 cm. Tumor size affects the performance of subjective assessment, LR1 and LR2, the IOTA simple rules and the RMI in discriminating correctly between benign and malignant adnexal masses. The likely explanation, at least in part, is

  1. Screening for cervical cancer in low-resource settings in 2011.

    Tambouret, Rosemary

    2013-06-01

    Cervical cancer remains the most common malignancy in women living in low- and middle-income countries, despite the decline of the disease in countries where cervical cytology screening programs have been implemented. To review the current incidence of cervical cancer in low-resource countries, the availability and types of screening programs, and the treatment options. Literature review through PubMed, Internet search, and personal communication. Although data are incomplete, available figures confirm that the rate of cervical cancer deaths and the availability of cervical cancer screening programs are inversely proportional and vary, in general, by the wealth of the nation. Despite the success of cervical cytology screening, many major health care organizations have abandoned screening by cytology in favor of direct visualization methods with immediate treatment of lesions by cryotherapy provided by trained, nonmedical personnel.

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

    Abstract. Background: Cancer of the cervix is the most common malignancy in women of childbearing age in Zambia. It is known to be associated with HIV infection and oncogenic strains of HPV. However, there are few studies of penile lesions as a predictor of malignant and premalignant cervical lesions in female partners.

  4. Clinical and pathological heterogeneity of cervical intraepithelial neoplasia grade 3.

    Hannah P Yang

    Full Text Available Cervical intraepithelial neoplasia grade 3 (CIN3, the immediate cervical cancer precursor, is a target of cervical cancer prevention. However, less than half of CIN3s will progress to cancer. Routine treatment of all CIN3s and the majority of CIN2s may lead to overtreatment of many lesions that would not progress. To improve our understanding of CIN3 natural history, we performed a detailed characterization of CIN3 heterogeneity in a large referral population in the US.We examined 309 CIN3 cases in the SUCCEED, a large population-based study of women with abnormal cervical cancer screening results. Histology information for 12 individual loop electrosurgical excision procedure (LEEP segments was evaluated for each woman. We performed case-case comparisons of CIN3s to analyze determinants of heterogeneity and screening test performance.CIN3 cases varied substantially by size (1-10 LEEP segments and by presentation with concomitant CIN2 and CIN1. All grades of CINs were equally distributed over the cervical surface. In half of the women, CIN3 lesions were found as multiple distinct lesions on the cervix. Women with large and solitary CIN3 lesions were more likely to be older, have longer sexual activity span, and have fewer multiple high risk HPV infections. Screening frequency, but not HPV16 positivity, was an important predictor of CIN3 size. Large CIN3 lesions were also characterized by high-grade clinical test results.We demonstrate substantial heterogeneity in clinical and pathological presentation of CIN3 in a US population. Time since sexual debut and participation in screening were predictors of CIN3 size. We did not observe a preferential site of CIN3 on the cervical surface that could serve as a target for cervical biopsy. Cervical cancer screening procedures were more likely to detect larger CIN3s, suggesting that CIN3s detected by multiple independent diagnostic tests may represent cases with increased risk of invasion.

    2010-03-01

    Full Text Available AIM: Cytological evaluation carries a great significance for the early detection and treatment of invasive cervical carcinoma precursors. Pap-smear test are considered as a quite effective screening method for this purpose. This screening can be easily performed at the first step health care centers without causing an economic burden if only selected patients were referred to second and third step medical care centers. In this program we aimed to perform a cross-sectional survey for cervix cancer in Trabzon center and surrounding area using cervical smears obtained at first step health care centers. MATERIAL-METHOD: A total number of 3000 cases with an age range of 25-64 were screened between March and May of 2007. This program was supported by USIDER. Smears obtained with cytological brushes were prepared with conventional methods and stained with Papanicolaou dye. Pap smears were reviewed by two pathologists according to 2001 Bethesda classification. RESULTS: A great majority of the smears (93.3 % were found to be satisfactory, while only 6.7 were found to be insufficient. Analysis of satisfactory cervical smears revealed cervical epithelial cell anomalies in 73 cases (2.4%; of these cases 57 (1.9% had atypical squamous cell of undetermined significance (ASC-US, 11 (0.4 % had low grade squamous intra-epithelial lesion (LSIL, 3 (0.1% high grade squamous intra-epithelial lesion (HSIL, and 2 (0.07 % had squamous cell carcinoma. CONCLUSION: Smears obtained at the first step health care centers were found to be satisfactory in a major proportion of the cases. Screening programs play a great role in the declining of cancer incidence. These screening programs should be included in national health politics. First step health care centers might be used for this purpose concerning the health economics.

    Although cervical spondylosis is a common disorder, dysphagia induced by osteophyte formation is uncommon. Fewer than one hundred cases of cervical osteophyte induced dysphagia have been reported, with little attention to the diagnosis by barium swallow. The radiological features of two cases treated surgically with good results are described. Both cases complained of dysphagia while one had associated respiratory obstruction on forward flexion of his neck. The features on barium study of cervical osteophytes causing dysphagia include deformity at the level of osteophyte formation, in both AP and lateral projections. Tracheal aspirations due to deformity at the laryngeal inlet and interference with epiglottic retroversion may be present. 8 refs., 3 figs

    2013-01-01

    Full Text Available Acquired cerebellar tonsillar herniation and syringomyelia associated with posterior fossa mass lesions is an exception rather than the rule. In the present article, we describe the neuroimaging findings in a case of 28-year-old female patient presented with a history of paraesthesia involving right upper limb of 8-month duration. Magnetic resonance imaging showed a giant retrocerebellar arachnoid causing tonsillar herniation with cervical syringomyelia. The findings in the present case supports that the one of the primary mechanism for the development of syringomyelia may be the obstruction to the flow of cerebrospinal fluid causing alterations in the passage of extracellular fluid in the spinal cord and leading to syringomyelia.

    1985-03-01

    Cervical tuberculous adenitis is being seen with increasing frequency in the United States; in the appropriate clinical setting it should be included in the differential diagnosis of an asymptomatic neck mass. Patients are typically young adults who are recent arrivals from Southeast Asia. A history of tuberculosis is not always elicited nor is the chest radiograph always abnormal. All of these patients have positive purified protein derivative tests unless they are anergic. The CT findings may lead to the diagnosis. Several CT patterns of nodal disease can be seen in tuberculous adenitis; some may mimic benign and neoplastic disease. The presence of a multiloculated or multichambered (conglomerate nodal) mass with central lucency and thick rims of enhancement and minimally effaced fascial planes is highly suggestive of tuberculous adenitis, especially if the patient has a strongly positive tuberculosis skin test.

  14. Tafazzin (TAZ promotes the tumorigenicity of cervical cancer cells and inhibits apoptosis.

    Mei Chen

    Full Text Available Tafazzin (TAZ is often aberrantly expressed in some cancers, including rectal cancer and thyroid neoplasms. However, the function of TAZ in cervical cancer cells remains unknown. This study aims to explore the expression and function of TAZ in cervical cancer cells. Here, we determined the expression of TAZ protein in normal cervical tissue (NC, n = 27, high-grade squamous intraepithelial lesions (HSIL, n = 26 and squamous cervical carcinoma (SCC, n = 41 by immunohistochemistry, the expression of TAZ protein gradually increased from NC to HSIL to SCC. TAZ was overexpressed or down-regulated in cervical cancer cells by stably transfecting a TAZ-expressing plasmid or a shRNA plasmid targeting TAZ. In vitro, the cell growth curves and MTT assays showed that TAZ may promote the growth and viability of cervical cancer cells. In vivo, xenografts experiment showed that TAZ may increase tumor-forming ability. The percentage of apoptosis cells analyzed by FACS and TUNEL assays consistently showed that TAZ inhibits apoptosis in cervical cancer cells. Furthermore, the Cleaved Caspase 9 and Cleaved Caspase 3 were down-regulated by TAZ in cervical cancer cells. Taken together, this study demonstrated that TAZ is overexpressed in cervical cancer and may promote tumorigenicity of cervical cancer cells and inhibit apoptosis.

  15. HPV-Based Screening, Triage, Treatment, and Followup Strategies in the Management of Cervical Intraepithelial Neoplasia

    Oscar Peralta-Zaragoza

    2013-01-01

    Full Text Available Cervical cancer is the second most common cause of death from cancer in women worldwide, and the development of new diagnostic, prognostic, and treatment strategies merits special attention. Many efforts have been made to design new drugs and develop immunotherapy and gene therapy strategies to treat cervical cancer. HPV genotyping has potentially valuable applications in triage of low-grade abnormal cervical cytology, assessment of prognosis and followup of cervical intraepithelial neoplasia, and in treatment strategies for invasive cervical cancer. It is known that during the development of cervical cancer associated with HPV infection, a cascade of abnormal events is induced, including disruption of cellular cycle control, alteration of gene expression, and deregulation of microRNA expression. Thus, the identification and subsequent functional evaluation of host proteins associated with HPV E6 and E7 oncoproteins may provide useful information in understanding cervical carcinogenesis, identifying cervical cancer molecular markers, and developing specific targeting strategies against tumor cells. Therefore, in this paper, we discuss the main diagnostic methods, management strategies, and followup of HPV-associated cervical lesions and review clinical trials applying gene therapy strategies against the development of cervical cancer.

  16. The Epidemiology of Human Papillomavirus Infection and Cervical Cancer

    F. Xavier Bosch

    2007-01-01

    Full Text Available Cervical cancer has been recognized as a rare outcome of a common Sexually Transmitted Infection (STI. The etiologic association is restricted to a limited number of viral types of the family of the Human Papillomaviruses (HPVs. The association is causal in nature and under optimal testing systems, HPV DNA can be identified in all specimens of invasive cervical cancer. As a consequence, it has been claimed that HPV infection is a necessary cause of cervical cancer. The evidence is consistent worldwide and implies both the Squamous Cell Carcinomas (SCC, the adenocarcinomas and the vast majority (i.e. > 95% of the immediate precursors, namely High Grade Squamous Intraepithelial Lesions (HSIL/Cervical Intraepithelial Neoplasia 3 (CIN3/Carcinoma in situ. Co-factors that modify the risk among HPV DNA positive women include the use of oral contraceptives (OC for five or more years, smoking, high parity (five or more full term pregnancies and previous exposure to other sexually transmitted diseases such as Chlamydia Trachomatis (CT and Herpes Simplex Virus type 2 (HSV-2. Women exposed to the Human Immunodeficiency Virus (HIV are at high risk for HPV infection, HPV DNA persistency and progression of HPV lesions to cervical cancer.

  17. Congenital cervical bronchogenic cyst: A case report

    Kiralj Aleksandar

    2015-01-01

    Full Text Available Introduction. Bronchogenic cysts are rare congenital anomalies of the embryonic foregut. They are caused by abnormal budding of diverticulum of the embryonic foregut between the 26th and 40th day of gestation. Bronchogenic cysts can appear in the mediastinum and pulmonary parenchyma, or at ectopic sites (neck, subcutaneous tissue or abdomen. So far, 70 cases of cervical localization of bronchogenic cysts have been reported. Majority of bronchogenic cysts have been diagnosed in the pediatric population. Bronchogenic cysts of the cervical area are generally asymptomatic and symptoms may occur if cysts become large or in case of infection of the cyst. The diagnosis is made based on clinical findings, radiological examination, but histopathologic findings are essential for establishing the final diagnosis. Treatment of cervical bronchogenic cyst involves surgical excision. Case Outline. Authors present a case of a 6-year-old female patient sent by a pediatrician to a maxillofacial surgeon due to asymptomatic lump on the left side of the neck. The patient had frequent respiratory infections and respiratory obstructions. Magnetic resonance imaging (MRI of the neck was performed and a well-circumscribed cystic formation on the left side of the neck was observed, with paratracheal location. The complete excision of the cyst was made transcervically. Histopathological findings pointed to bronchogenic cyst. Conclusion. Cervical bronchogenic cysts are rare congenital malformations. Considering the location, clinical findings and the radiological features, these cysts resemble other cervical lesions. Surgical treatment is important because it is both therapeutic and diagnostic. Reliable diagnosis of bronchogenic cysts is based on histopathological examination.

    Cervical cancer (CC) is the fourth cause of mortality by neoplasia in women worldwide. The use of immunomarkers is an alternative tool to complement currently used algorithms for detection of cancer, and to improve selection of therapeutic schemes. Aberrant expression of Ezrin and E-cadherin play an important role in tumor invasion. In this study we analyzed Ezrin and E-cadherin expression in liquid-based cervical cytology samples, and evaluated their potential use as prognostic immunomarkers. Immunocytochemical staining of Ezrin and E-cadherin was performed in cervical samples of 125 patients. The cytological or histological diagnostic was performed by Papanicolaou staining or H&E staining, respectively. HPV genotyping was determined using INNO-LIPA Genotyping Extra kit and the HPV physical status by in situ hybridization. Ezrin expression in HaCaT, HeLa and SiHa cell lines was determined by immunocytochemistry, immunofluorescence and Western blot. High Ezrin expression was observed in cervical cancer samples (70%), samples with multiple infection by HR-HPV (43%), and samples with integrated viral genome (47%). High Ezrin expression was associated with degree of SIL, viral genotype and physical status. In contrast, low E-cadherin expression was found in cervical cancer samples (95%), samples with multiple infection by HR-HPV/LR-HPV (87%) and integrated viral genome (72%). Low E-cadherin expression was associated with degree of SIL and viral genotype. Interestingly, Ezrin nuclear staining was associated with degree of SIL and viral genotype. High Ezrin expression, high percent of nuclear Ezrin and low E-cadherin expression behaved as risk factors for progression to HSIL and cervical cancer. Ezrin and E-cadherin expression profile in cervical cytology samples could be a potential prognostic marker, useful for identifying cervical lesions with a high-risk of progression to cervical cancer.

    Cervical spinal cord lesions in the anterior spinal artery syndrome were delineated on magnetic resonance images (MRI) in four patients. The lesion was always seen anteriorly in the cervical cord. On T2-weighted images, the lesions appeared hyperintense relative to the normal spinal cord, while on T1-weighted images, two chronic lesions appeared hypointense, with local atrophy of the cord. In one case, repeated T1-weighted images showed no signal abnormality 4 days after the ictus, but the lesion became hypointense 18 days later, when contrast enhancement was also recognized after injection of Gd-DTPA; this sequence of intensity changes was similar to that of cerebral infarction. The extent of the lesion seen MRI correlated closely with neurological findings in all cases. Although the findings may not be specific, MRI is now the modality of choice for confirming the diagnosis in patients suspected of having an anterior spinal artery syndrome. (orig.)

    Jeon, Seong Woo; Kim, See Hyung; Kwon, Sun Young

    2013-01-01

    Metastasis of malignant tumors to the kidney is clinically rare and often discovered by autopsy. Primary lymphoma and lung cancer are known that can metastasize to the kidney. Other malignant tumor metastasis to the kidney is very unusual. Primary cervical cancer metastasis to adjacent pelvic organs and lymph nodes are well known followed by abdominal solid organs such as the liver and adrenal glands. However, reported primary cervical cancer metastasis to the kidney is extremely rare and mostly appeared as bilateral multiple renal masses. We report here on a rare case of unilateral single renal metastasis from primary cervical cancer after concur- rent chemoradiotherapy.

  1. Detection of human papillomavirus by hybrid capture and real time PCR methods in patients with chronic cervicitis and cervical intraepithelial

    2016-07-01

    Full Text Available Background and objectives:Cervical cancer due to Human papillomavirus (HPV is one of the leading causes of morbidity and mortality in women. Testing of HPV can identify women who are at risk of cervical cancer. Nowadays, molecular methods like real time polymerase chain reaction (PCR and hybrid capture technique are applied for detecting HPV in cervical specimens. The objective of the present study was to determine the rate of HPV infection in women with chronic cervicitis and cervical intraepithelial neoplasia (CIN by a commercial real time polymerase chain reaction test kit and by a hybrid capture HPV DNA test. Methods:Women aged between 20 to 55 years with chronic cervicitis and CIN were enrolled in the study after obtaining informed consent. Cervical specimen was collected by using cervical brush and stored in transport medium until used. HPV was detected by High Risk Screen Real-TM Quant 2x (Sacace, Biotechnologies SrI, Italy real time PCR kit (HR RT-PCR and by Hybrid Capture-2 High-Risk HPV DNA (Hc-2; Digene Corporation, USA test. Results: Total 72 women with chronic cervicitis and CIN of different grades were included in the study. Out of this, HPV infection detected by HR RT-PCR was 31 (43% and by Hc-2 was 14 (19.4%. Both the tests were able to detect HPV infection in all the CIN 3 cases and in most of the CIN 2 cases. However, HR RT-PCR detected higher number of HPV in chronic cervicitis and CIN1 cases. Conclusion:The study has shown that HR RT-PCR and Hc-2 tests are equally effective in detecting HPV infection in patients with CIN 2 and CIN 3 lesions. However, HR RT-PCR is more sensitive test for detecting HPV in chronic cervicitis and early CIN lesions and, therefore can be used in epidemiological study to detect presence of HPV in general population.

    Astrocytomas are relatively common glial neoplasm of the central nervous system, but only a small percentage of them are located in the spinal cord, with a predilection for the cervical and dorsal regions. In most cases, extend longitudinally, affecting several cord segments. Pain is a frequent symptom of local character bone segments involving the tumor, associated with sensory deficit and / or motor. The following is the case of a 60 year old woman with cervical cord astrocytoma extended to the brainstem.

    Most non-screen-detected cervical cancers are advanced stage. We assess the potential for cytology to expedite diagnosis when used outside of routine call and recall screening for cervical cancer. Two cohorts of women with cytology that did not appear to have been taken as part of routine screening, nested within a census of cervical cytology, in England between April 2007 and March 2010 were studied: 93,322 women aged 40-69 at first cytology, and 14,668 women aged ≥70. The diagnostic performance of high grade cervical squamous intraepithelial lesion (HSIL) or worse cytology was estimated. We also estimated case-fatality from stage distribution in women aged ≥66 with and without cytology in the year prior to diagnosis. There were 259 cancers diagnosed in women aged 40-69 at first cytology, and 78 in women aged ≥70. The sensitivity of cytology ≥ HSIL for cancer was 89% and 83% respectively, and the number of women needed to test to identify one cancer was 404 (95% confidence interval [CI]: 355-462) and 226 (95% CI: 177-292) respectively. Women aged ≥66 with cytology within a year of diagnosis had earlier stage cancers than those without, corresponding to a 17-22% reduction in case fatality. Cervical cytology is an excellent identifier of cancer among women tested outside routine screening call and recall. Its use as a triage tool, for instance in women with vague gynaecological symptoms, could facilitate earlier stage diagnosis and reduce cervical cancer mortality. © The Author(s) 2015.

    Cancer of the breast is the second most common cause of cancer in women. Mass in the breast, whether benign or malignant is a cause of anxiety to the patients and the family members. All breast lumps are considered to be carcinomas until proved otherwise and are the causes of concern both for the patient and surgeon. This is a retrospective study conducted in Kathmandu Model Hospital for a total duration of three years from August 2007 to August 2010. 114 sample of breast tissue sent for histopathology were studied. Peak incidence of benign lesion was in between 21-30 years and malignant lesions in between 31-50 years. No breast lesions were seen in the first decade of life. Cancer of the breast was seen in 12.28% of cases. Fibroadenoma and fibrocystic disease were the commonest benign lesion and infiltrating ductal carcinoma was the commonest malignant lesion. Specimens from 10 male breasts were received. Gynaecomastia was the most common lesion encountered in males. Infiltrating ductal carcinoma was seen in a 70 year old male. Breast cancer is one of the commonest causes of breast lump particularly in women and is growing public health problem in Nepal.

    The purpose of this study was to investigate the application of histogram analysis of apparent diffusion coefficient (ADC) in characterizing pathologic features of cervical cancer and benign cervical lesions. This prospective study was approved by the institutional review board, and written informed consent was obtained. Seventy-three patients with cervical cancer (33-69 years old; 35 patients with International Federation of Gynecology and Obstetrics stage IB cervical cancer) and 38 patients (38-61 years old) with normal cervix or cervical benign lesions (control group) were enrolled. All patients underwent 3-T diffusion-weighted imaging (DWI) with b values of 0 and 800 s/mm(2). ADC values of the entire tumor in the patient group and the whole cervix volume in the control group were assessed. Mean ADC, median ADC, 25th and 75th percentiles of ADC, skewness, and kurtosis were calculated. Histogram parameters were compared between different pathologic features, as well as between stage IB cervical cancer and control groups. Mean ADC, median ADC, and 25th percentile of ADC were significantly higher for adenocarcinoma (p = 0.021, 0.006, and 0.004, respectively), and skewness was significantly higher for squamous cell carcinoma (p = 0.011). Median ADC was statistically significantly higher for well or moderately differentiated tumors (p = 0.044), and skewness was statistically significantly higher for poorly differentiated tumors (p = 0.004). No statistically significant difference of ADC histogram was observed between lymphovascular space invasion subgroups. All histogram parameters differed significantly between stage IB cervical cancer and control groups (p histogram analysis may help to distinguish early-stage cervical cancer from normal cervix or cervical benign lesions and may be useful for evaluating the different pathologic features of cervical cancer.

    The aim of this study was to evaluate epigenetic status of cyclin A1 in human papillomavirus-associated cervical cancer. Y. Tokumaru et al., Cancer Res 64, 5982-7 (Sep 1, 2004)demonstrated in head and neck squamous-cell cancer an inverse correlation between cyclin A1 promoter hypermethylation and TP53 mutation. Human papillomavirus-associated cervical cancer, however, is deprived of TP53 function by a different mechanism. Therefore, it was of interest to investigate the epigenetic alterations during multistep cervical cancer development. In this study, we performed duplex methylation-specific PCR and reverse transcriptase PCR on several cervical cancer cell lines and microdissected cervical cancers. Furthermore, the incidence of cyclin A1 methylation was studied in 43 samples of white blood cells, 25 normal cervices, and 24, 5 and 30 human papillomavirus-associated premalignant, microinvasive and invasive cervical lesions, respectively. We demonstrated cyclin A1 methylation to be commonly found in cervical cancer, both in vitro and in vivo, with its physiological role being to decrease gene expression. More important, this study demonstrated that not only is cyclin A1 promoter hypermethylation strikingly common in cervical cancer, but is also specific to the invasive phenotype in comparison with other histopathological stages during multistep carcinogenesis. None of the normal cells and low-grade squamous intraepithelial lesions exhibited methylation. In contrast, 36.6%, 60% and 93.3% of high-grade squamous intraepithelial lesions, microinvasive and invasive cancers, respectively, showed methylation. This methylation study indicated that cyclin A1 is a potential tumor marker for early diagnosis of invasive cervical cancer

  15. MicroRNA expression variability in human cervical tissues.

    Patrícia M Pereira

    Full Text Available MicroRNAs (miRNAs are short (approximately 22 nt non-coding regulatory RNAs that control gene expression at the post-transcriptional level. Deregulation of miRNA expression has been discovered in a wide variety of tumours and it is now clear that they contribute to cancer development and progression. Cervical cancer is one of the most common cancers in women worldwide and there is a strong need for a non-invasive, fast and efficient method to diagnose the disease. We investigated miRNA expression profiles in cervical cancer using a microarray platform containing probes for mature miRNAs. We have evaluated miRNA expression profiles of a heterogeneous set of cervical tissues from 25 different patients. This set included 19 normal cervical tissues, 4 squamous cell carcinoma, 5 high-grade squamous intraepithelial lesion (HSIL and 9 low-grade squamous intraepithelial lesion (LSIL samples. We observed high variability in miRNA expression especially among normal cervical samples, which prevented us from obtaining a unique miRNA expression signature for this tumour type. However, deregulated miRNAs were identified in malignant and pre-malignant cervical tissues after tackling the high expression variability observed. We were also able to identify putative target genes of relevant candidate miRNAs. Our results show that miRNA expression shows natural variability among human samples, which complicates miRNA data profiling analysis. However, such expression noise can be filtered and does not prevent the identification of deregulated miRNAs that play a role in the malignant transformation of cervical squamous cells. Deregulated miRNAs highlight new candidate gene targets allowing for a better understanding of the molecular mechanism underlying the development of this tumour type.

    Raman spectroscopy measures the inelastically scattered light from tissue that is capable of identifying native tissue biochemical constituents and their changes associated with disease transformation. This study aims to characterize the Raman spectroscopic properties of cervical tissue associated with the multi-stage progression of cervical precarcinogenic sequence. A rapid-acquisition fiber-optic near-infrared (NIR) Raman diagnostic system was employed for tissue Raman spectral measurements at 785 nm excitation. A total of 68 Raman spectra (23 benign, 29 low-grade squamous intraepithelial lesions (LSIL) and 16 high grade squamous intraepithelial lesions (HSIL)) were measured from 25 cervical tissue biopsy specimens, as confirmed by colposcopy-histopathology. The semi-quantitative biochemical modeling based on the major biochemicals (i.e., DNA, proteins (histone, collagen), lipid (triolein) and carbohydrates (glycogen)) in cervical tissue uncovers the stepwise accumulation of biomolecular changes associated with progressive cervical precarcinogenesis. Multi-class partial least squares-discriminant analysis (PLS-DA) together with leave-one tissue site-out, cross-validation yielded the diagnostic sensitivities of 95.7%, 82.8% and 81.3%; specificities of 100.0%, 92.3% and 88.5%,for discrimination among benign, LSIL and HSIL cervical tissues, respectively. This work suggests that the Raman spectral biomarkers have identified the potential to be used for monitoring the multi-stage cervical precarcinogenesis, forming the foundation of applying NIR Raman spectroscopy for the early diagnosis of cervical precancer in vivo at the molecular level.

    The aim of this study was to assess the performance of shear wave elastography combined with BI-RADS classification of greyscale ultrasound images for benign/malignant differentiation in a large group of patients. One hundred and seventy-five consecutive patients with solid breast masses on routine ultrasonography undergoing percutaneous biopsy had the greyscale findings classified according to the American College of Radiology BI-RADS. The mean elasticity values from four shear wave images were obtained. For mean elasticity vs greyscale BI-RADS, the performance results against histology were sensitivity: 95% vs 95%, specificity: 77% vs 69%, Positive Predictive Value (PPV): 88% vs 84%, Negative Predictive Value (NPV): 90% vs 91%, and accuracy: 89% vs 86% (all P>0.05). The results for the combination (positive result from either modality counted as malignant) were sensitivity 100%, specificity 61%, PPV 82%, NPV 100%, and accuracy 86%. The combination of BI-RADS greyscale and shear wave elastography yielded superior sensitivity to BI-RADS alone (P=0.03) or shear wave alone (P=0.03). The NPV was superior in combination compared with either alone (BI-RADS P=0.01 and shear wave P=0.02). Together, BI-RADS assessment of greyscale ultrasound images and shear wave ultrasound elastography are extremely sensitive for detection of malignancy.

    The cervical spine may be specifically involved in crystal-associated arthropathies. In this article, we focus on the three common crystals and diseases: hydroxyapatite crystal deposition disease, calcium pyrophosphate dihydrate (CPPD) deposition disease, and monosodium urate crystals (gout). The cervical involvement in crystal-associated diseases may provoke a misleading clinical presentation with acute neck pain, fever, or neurological symptoms. Imaging allows an accurate diagnosis in typical cases with calcific deposits and destructive lesions of the discs and joints. Most of the cases are related to CPPD or hydroxyapatite crystal deposition; gout is much less common. (orig.)
