Abstract

Background: Cervical cancer is the third most common gynecologic cancer in women worldwide. Cervical cancer has lower incidence and mortality rates than uterine corpus and ovarian cancer, as well as many other cancer sites. Unfortunately, in countries that do not have access to cervical cancer screening and prevention programs, cervical cancer remains the second most common type of cancer. Staging of the disease is made clinically. The aim of this study was to evaluate the role of magnetic resonance imaging (MRI) for diagnosing the invasion of cancer to organs and staging of cervical cancer and the relationship between clinical and pathological findings and the sensitivity and specificity of the assay in cervical cancer.

Methods: The study included records of 40 patients with cervical cancer that undergo surgery or Chemoradiation in Firoozgar University Hospital. In this study that made retrospectively, non-randomized, the MRI reports and clinical findings records and pathology results was discussed. The sensitivity and specificity of MRI for diagnosing the invasion to parameters, bladder, rectum, vagina, pelvic wall and it’s accuracy to determine tumor stage has been set.

Results: A total of 40 patients with pathology information of cervical cancer was retrospectively reviewed in the study. The patients were 28-83 years old by mean age of 49.3 Pathology of cervical cancer in 80% of cases was SCC, 15% adenocarcinoma and 5% melanoma. The sensitivity and specificity of MRI for diagnosing invasion of parameter was 76% and 88%. The sensitivity of MRI in the detection of bladder invasion was 100% and specificity of 100%. The sensitivity of MRI in the diagnosis of rectal invasion was 50% and specificity of 100%. The sensitivity of MRI in the diagnosis of pelvic wall invasion was 100% and specificity of 86%. Sensitivity in detecting invasion into the upper third of the vagina was 100%.

Conclusion: Overall, this study showed a good sensitivity and specificity for detecting invasion into the bladder, vagina, pelvic wall and parameters and good specificity for the diagnosis of rectal invasion and acceptable accuracy at 67.5% for detection of tumor stage by MRI show.

Abstract
Background: Cervix insufficiency is diagnosed based on a previous history of pregnancy loss in the second trimester, followed by painless cervical dilatation or premature rupture of the fetal membranes. Abnormal cervical tissue structural appears to be the cause of this complication. There are no diagnostic methods for cervical insufficiency before pregnancy, but magnetic resonance imaging (MRI), hysterosalpingography, and ultrasound can detect uterine anomalies that are risk factors for cervical insufficiency. Cerclage is known as a common procedure for prevention of the preterm labor, caused by cervix insufficiency. This study aimed to evaluate the prevalence of cerclage and it’s complications and prognosis based on the patient’s age, history of cervical insufficiency, history of preterm labor, history of miscarriage, curettage, and cervical and vaginal abnormalities.
Methods: A retrospective cohort study was conducted, including 65 patients, from March 2012 to March 2018, in Valiasr Hospital, Tehran, Iran. Data including the age, history of cervical insufficiency, history of abortion, history of cervix surgery and curettage, gestational age, presence of vaginal and cervical anomaly as well as complications such as bleeding and severe cervical pain and prognosis of cerclage were extracted.
Results: In our study, 65 women who undergone cerclage were evaluated, the mean age of the participants was 28.4 years. Abortion was present in 27.7% of cases, 16.9% once, 7.7% twice and 3.1% three times. In 21.5% of cases, there was a history of curettage and 66.2% had a history of preterm labor. For 4.6% of the subjects, the length of cervix was under 10 mm. Gestational age at the end of cerclage was under 26 weeks in 5.8% of patients. The termination of pregnancy was higher in patients with lower gravida, and the termination of pregnancy was significantly higher in those who were not curetted (P= 0.001). There were no complications, and the prognosis is considered good, in case the termination is above 32 weeks. The birth weight mean was 3041.5 grams. According to our study, the failure of the cerclage is associated with previous history of dilation and curettage (D&C) and higher gravidity.
Conclusion: Putting all the results together, 80% of the cerclage, performed in our institution were successful, without any complications.

Abstract
According to the official statistics of the World Health Organization (WHO), cervical cancer is one of the most common cancers among women after breast, colorectal, and lung cancers. The US Centers for Disease Control and Prevention (CDC) says all women have the chance to get the disease, and women over the age of 30 are more likely to get it. However, this cancer is a types of cancer that can be prevented through vaccination. This study aimed to investigate the role of vaccines in the prevention of cervical cancer. In this review study, articles published between 2016-2022 from PubMed, SID, Cochrane Library, Science Direct, and Google Scholar databases were examined. Keywords Papilloma vaccine and cervical cancer in Persian sources and HPV vaccine and Cervical Cancer in English sources were used. The subject search was also performed using MeSH medical subject headings and through the Pubmed database. Vaccination against human papillomavirus is the most cost-effective public health measure against cervical cancer. In many developed and developing countries, serious programs are underway for HPV vaccination and screening for cervical cancer. In most countries, HPV vaccination has been added to their mandatory immunization programs, effectively reducing the incidence of cervical infections and cancers. In countries where vaccination is not complete, health education and screening programs such as PAP smears every 2 years for all women and every year for those with high cancer risk or abnormal smears, have been consolidated. HPV vaccination is highly effective and has been added to immunization programs in many countries. Nowadays, three types of vaccines have been presented, of which the 9-valent Gardasil vaccine is more effective than the other two types, but in terms of cost-effectiveness, the 4-valent Gardasil vaccine is more suggested. Due to the high prevalence of cervical cancer in Iran, it is suggested that the HPV vaccine be used, screening tests be optimized and performed on a regular basis, and ways to prevent cervical cancer be taught.

Abstract
Background: The study of the angles between the vertebrae and the curvatures of the spine plays an essential role in the pathogenesis of spinal disorders. Among the essential topics, the cervical sagittal parameters are widely used in evaluating cervical spine disorders and surgery. Measurement of cervical lordosis curves in healthy people is influenced by various factors. This study was conducted in order to investigate the average indexes of the cervical vertebrae in simple graphs in normal people.
Methods: In this descriptive study, using Gunya and Radiant software, radiographic photographs of the lateral view of the cervical region of 50 people (28 men and 22 women) who were referred for purposes other than problems related to neck pain were examined. Patients who were candidates for surgery and congenital disorders of the cervical spine were excluded. The study was conducted between March to April 2022. In this study, 12 cervical indexes were comprehensively measured and the scope of their changes in relation to age and gender was investigated. The measurements were conducted by an experienced radiologist.
Results:  In this study, 50 participants including 28 male (58%) and 22 female (44%) were included in the study. The mean age of participants 38.42 ± 2.1 years. After comparing the two genders, except for C0-C2/C2-C7 ratio index (4.9 in men and 2.6 in women) (P= 0.012), no significant difference was seen for other indexes (P> 0.05). After comparing the two groups, a significant difference was seen only in the T1 slope (T1S) index, which was significantly higher in people over 35 years old than in people under 35 years old (71.15 vs. 69.04) (P=0.049).
Conclusion: The evidence from this study shows that T1S increases with age and C0-C2/C2-C7 is significantly less in women than in men. These findings can be used to diagnose pathology or destructive changes in the elderly, to evaluate movement disorders, the effectiveness of treatment, and to determine the outcome.
