Hereditary Multiple Exostoses (HME) is a rare pediatric disorder caused by loss-of-function mutations in the genes encoding the heparan sulfate (HS)-synthesizing enzymes EXT1 or EXT2. HME is characterized by formation of cartilaginous outgrowths-called osteochondromas- next to the growth plates of many axial and appendicular skeletal elements. Surprisingly, it is not known whether such tumors also form in endochondral elements of the craniofacial skeleton. Here, we carried out a retrospective analysis of cervical spine MRI and CT scans from 50 consecutive HME patients that included cranial skeletal images...

Epithelial-mesenchymal transition (EMT) is now well documented to be involved in the development of endometriosis through the promotion of invasion and fibrogenesis. To date, several factors have been reported to be involved in EMT in endometriosis. The eukaryotic translation initiation factor 3 subunit e (eIF3e) protein is a component of the multisubunit eIF3 complex essential for cap-dependent translation initiation. The aim of this study was to investigate whether eIF3e is involved in EMT in endometriosis...

This case report of a 36-year-old woman with a diagnosis of cervical pregnancy describes a novel approach to this rare form of ectopic pregnancy, which was successfully treated with systemic and local methotrexate (MTX) therapy combined with hysteroscopic resection. After local and systemic administration of MTX, the patient underwent hysteroscopic resection of the cervical pregnancy using a 27 bipolar resectoscope with a 4-mm loop. The cervical pregnancy was completely treated, and satisfactory hemostasis was achieved with electrocoagulation...

In recent decades, miRNA has been reported as a crucial modulator in some biology progressions. This work aims to assess the expression and role of miR-let-7a and pyruvate kinase muscle isozyme M2 (PKM2) in CC tissues and cell lines. Here, we identified that miR-let-7a expression was decreased in CC tissues, and SiHa and HeLa cells (all P < 0.001), however, PKM2 expression was increased in these samples. Statistically, miR-let-7a was inversely associated with PKM2 mRNA or protein (p = 0.013, p = 0.015, respectively)...

OBJECTIVE: Previous studies have identified that kazrin is a constituent of desmosome and influences intercellular adhesion, growing development and morphology. We previously cloned another new isoform, kazrin F and found that it has anti-apoptotic effects on human glioma cell line. To further explore whether kazrin F is involved in tumorigenesis, we investigated its expression and role in cervical cancer (CC) cells. METHODS: The role of kazrin F and miR-186 in CC was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, colony formation, transwell, and apoptosis assays...

REVIEW
Catherine M O'Connell, Morgan E Ferone
Etiology, transmission and protection: Chlamydia trachomatis is the leading cause of bacterial sexually transmitted infection (STI) globally. However, C. trachomatis also causes trachoma in endemic areas, mostly Africa and the Middle East, and is a leading cause of preventable blindness worldwide. Epidemiology, incidence and prevalence: The World Health Organization estimates 131 million new cases of C. trachomatis genital infection occur annually. Globally, infection is most prevalent in young women and men (14-25 years), likely driven by asymptomatic infection, inadequate partner treatment and delayed development of protective immunity...

Cervical cancer is considered as a gynecological malignancy accompanied with high rates of mortality across the world. Effective diagnostic, prognostic markers as well as therapeutic targets are necessary to be explored. The p27 and PTEN are known to modulate tumor cell growth and proliferation. However, the molecular mechanisms modulating these genes have not completely been elucidated. In our study, real-time (RT) quantitative PCR indicated that miR‑940 levels were upregulated in human cervical cancer tissue samples and cell lines...

Clear cell carcinoma (CCC) of the uterine cervix without prenatal diethylstilbestrol exposure is rare, and its etiology is unclear. We present a case of cervical CCC presenting as a submucosal tumor, which strongly suggests an association between cervical endometriosis and cervical CCC. A 56-year-old postmenopausal Japanese woman visited a gynecologic clinic with a complaint of watery vaginal discharge. A few atypical cells suggesting adenocarcinoma were detected in a cervical cytologic specimen. Magnetic resonance imaging revealed a cystic lesion with a solid component at the uterine cervix...

Cervical pregnancy can be complicated by perfuse vaginal bleeding. Mechanical compression directed at tamponing the cervical vessels can control hemostasis. There are several types of balloon catheters that have been described for cervical compression. However use of a double balloon catheter is a novel approach for cervical tamponade, as one balloon is positioned below the external cervical os and the second balloon is situated above in the internal cervical os. This compresses the cervix from internal os to external os between the two balloons, forming a "cervical sandwich...

Both human papillomavirus (HPV) infection and the aberrant Ras associated domain family gene 1A (RASSF1A) promoter methylation status participate in the pathogenesis of cervical cancer. Some studies suggest that E6, and E7 are involved in the pathogenetic mechanisms of RASSF1A. We mainly explored a possible involvement of HPV16 oncogenes E6 or/and E7 in RASSF1A promoter methylation status and possible roles of RASSF1A gene methylation in cervical cancer. Bisulfite genomic sequencing (BGS) PCR combined with TA clone, methylation-specific PCR (MSP) were used to analyze methylation status of the RASSF1A gene promoter in HPV16/18-positive and HPV-negative cervical cancer cell lines; ectopically expressed HPV16 E6, E7 and E6/E7 cervical cancer cell lines; normal cervical and cervical cancer tissues...

BACKGROUND: Ossification of the posterior longitudinal ligament (OPLL) is defined as ectopic bone formation within the posterior longitudinal ligament. Although various OPLL features (including the extent, shape, and thickness of the OPLL as well as the presence of dural ossification) have been defined in the literature, we are not aware of any systematic reviews that have summarized the associations between these features and clinical outcomes following surgery. The objective of the present study was to conduct a systematic review of the literature to determine whether OPLL characteristics are predictive of outcome in patients undergoing surgery for the treatment of cervical myelopathy...

Thyroid scintigraphy holds a key place in the etiologic workup of neonatal hypothyroidism. Routine screening for this disorder in maternity hospitals in industrialized countries, for nearly 40 years, has permitted early treatment and thereby helped to prevent its physical and mental complications. Neonatal hypothyroidism affects approximately 1 in 3000 births. The most common causes are abnormal thyroid gland development and defective hormone synthesis by an eutopic thyroid gland. The incidence of the latter has risen in recent years, for reasons that remain unclear...

The wide use of assisted reproductive technologies has contributed to the increased risk of ectopic and subsequently heterotopic pregnancy (HP) rate. Cervical ectopic pregnancy is a very rare and life-threatening form of ectopic pregnancy that can also present as HP. We are describing here a case of 34-year-old woman who presented with bleeding heterotopic cervical pregnancy (HCP). The concomitant viable cervical and intrauterine pregnancies were diagnosed at 8 weeks of gestation. Selective fetal reduction was done for cervical pregnancy following which uterine artery embolization was done as a life-saving measure, and subsequently, injection methotrexate was also given...

Loss of the tumor suppressor NDRG2 has been implicated in the development of oral squamous cell carcinoma (OSCC), acting by modulating PI3K/AKT-mediated dephosphorylation of PTEN at S380/S382/T383 (STT). Here we show that the majority of OSCC tumors with lymph node metastasis, a major prognostic factor, exhibit high levels of phosphorylated AKT-S473 and PTEN-STT and low levels of NDRG2 expression. In Ndrg2-deficient mice, which develop a wide range of tumors, we developed a model of OSCC by treatment with the tobacco surrogate 4-nitroquinoline-1-oxide (4-NQO)...
