BACKGROUND: Most studies that have compared programmed intermittent epidural bolus (PIEB) with continuous epidural infusion regimens have included patient-controlled epidural analgesia and/or manual bolus as rescue analgesia for breakthrough pain. Consequently, the optimal time interval between PIEB is yet to be determined. We designed a study to establish the optimal time interval between PIEB of 10 mL of bupivacaine 0.0625% with fentanyl 2 μg/mL to produce effective analgesia in 90% of women during first stage of labor without breakthrough pain...

As the second most common gynecologic malignant tumors with a high mortality rate, cervical cancer jeopardizes women's life worldwide. The low cure rate in cervical cancer patients is mainly attributed to the lack of effective therapies. One feasible novel strategy is to develop immune-based approaches such as adoptive cell immunotherapy of DCCIKs which represents a promising nontoxic antineoplastic immunotherapy preferred in clinic practice. However, the therapeutic effect is not as efficient as anticipated...

OBJECTIVE: Cardio ankle vascular index (CAVI) is reflecting stiffness of the arterial tree from the origin of aorta to the ankles. We observed elevated CAVI in patients who suffered from apoplexy attack. To clarify the role and the mechanism by which arterial stiffness elevated just after apoplexy attack, the effect of enhanced intracranial pressure (ICP) by injecting saline into the cisterna magna of the rabbit on blood pressure, CAVI and cervical blood flow, were studied. Furthermore the role of sympathetic nerve was studied...

Introduction Bevacizumab is a recombinant humanized monoclonal antibody against vascular endothelial growth factor (VEGF) (Avastin; Genetech, Inc, San Francisco, CA). Angiogenesis is blocked by the binding of bevacizumab to VEGF, inhibiting the binding of this ligand to the VEGF receptor. On August 14, 2014 the Food and Drug Administration (FDA) approved use of bevacizumab in persistent, recurrent, or metastatic cervical cancer. Areas Covered Herein we review pharmacodynamics and kinetics, clinical data and treatment-related toxicities of bevacizumab in the treatment of metastatic, recurrent or persistent cervical cancer...

BACKGROUND AND OBJECTIVE: Ultrasound-guided blocks of the cervical plexus are established anesthetic procedures for carotid endarterectomy. This randomized, double-blind, placebo-controlled study tested the hypothesis that an additional ultrasound-guided periarterial injection of local anesthetic leads to a lower frequency of periarterial supplementation by the surgeon. METHODS: A total of 40 patients were randomly assigned to 1 of 2 groups. In both groups an ultrasound-guided intermediate cervical plexus block (20 ml of 0...

INTRODUCTION: The mandible consists of different segments, each of which possess its own specific characteristics regarding emergence, ossification during growth and pathologies. Orthodontists need to be very familiar with these developmental anomalies if they are to avoid failure in their orthopedic or orthodontic treatments and in order to understand the reasons for the lack of success of "conventional" treatments. Each segment must develop correctly if the mandible is to achieve optimal development and occupy a normal position within the cranio-facial complex...

PURPOSE: The generation and tissue origination of disc-associated axial pain is still under exploration. This study was performed to evaluate disc-associated axial pain and to explore whether it originates in the disc or its surrounding components. METHODS: A 6-year series of 88 single-level Smith-Robinson disc and posterior longitudinal ligament (PLL) resections performed to treat single-level cervical spondylotic myelopathy was retrospectively examined. All single-level anterior disc decompressions were performed under local infiltration anesthesia; the PLL was not anesthetized to avoid cervical cord block...

PURPOSE: Platelets have multiple functions and they also play an important role in malignancies. Elevated platelet count and thrombocytosis at the time of diagnosis in patients with many solid tumors correlates with prognosis and is associated with poor survival. The aim of the following report is to review the literature concerning elevated platelet count and thrombocytosis in gynecologic malignancies. METHOD: A PubMed search of all English literature peer-reviewed publications was performed containing the terms elevated platelet count or thrombocytosis and vulvar cancer, cervical cancer, endometrial cancer, and ovarian cancer...

A retrospective analysis was performed to describe the cytomorphological and histopathological findings and human papillomavirus (HPV) genotypes for glassy cell carcinoma (GCC) of the uterine cervix. Five cases of cervical GCC, in which the glassy cell features constituted at least 95% of the specimen, were included. Four patients had stage IIB GCCs and one had stage IIIB GCC. All patients underwent concurrent chemoradiation therapy. Based on pretreatment cytology, only 1 of the 5 cases was correctly diagnosed as GCC...

RATIONALE: Development of cervical squamous carcinoma (CXCA) is accompanied by changes in estrogen receptors (ERs, ERα and ERβ) and ezrin expression; however, reports have been conflicting. Using histologically documented staging of cervical biopsies, we determined ezrin and ER relationships during CXCA development. METHODS: Immunoreactive (ir) ezrin, ir-ERα, and ir-ERβ were studied in normal epithelium, carcinoma in situ/cervical intraepithelial neoplasia (CIN) 1 to 3, and local invasion or metastatic CXCA...

Sarcomatoid squamous cell carcinoma (SSCC) of the uterine cervix is a rare malignancy with uncertain pathogenesis and aggressive clinical behavior. The diagnosis of this tumor poses a challenge to the cytopathologist since accurate diagnosis is based on identification of two malignant components, that is, epithelial and sarcomatoid. Most cases usually lack the sarcomatoid component on Papanicolaou test (Pap test). Therefore, a poorly differentiated carcinoma or malignant neoplasm is the most often rendered diagnosis...

In human tumor cells, experimental and clinical evidence indicates that some factors involved in signal transduction and cell growth can also modulate the response to chemotherapeutic treatment. The aim of the present study was to investigate the role of folic acid (FA) as a modulator of carboplatin (CBDCA) activity. Genotoxicity and cytotoxicity induced by CBDCA alone and in combination with FA were assessed in cultured HeLa cells. We used comet assay, mitotic index analysis, MTT and NR assays, cytokinesis-block micronucleus cytome assay and annexin V-IP as different cytotoxicity and genotoxicity approaches for human cervical carcinoma cell line studies...

Increasing utilization of interventional techniques in managing chronic spinal pain, specifically facet joint interventions and sacroiliac joint injections, is a major concern of healthcare policy makers. We analyzed the patterns of utilization of facet and sacroiliac joint interventions in managing chronic spinal pain. The results showed significant increase of facet joint interventions and sacroiliac joint injections from 2000 to 2014 in Medicare FFS service beneficiaries. Overall, the Medicare population increased 35 %, whereas facet joint and sacroiliac joint interventions increased 313...

Here, we compared the effects of inhibitors of three phosphatidylinositol-3-kinase-related kinases, ATM, ATR a DNA-PK, on radiosensitization of cervical carcinoma cells. We demonstrated that DNA-PK inhibitor NU7441 enhanced phosphorylation of Chk1 and Chk2 kinases 2 h after irradiation of HeLa cells at a dose of 8 Gy in contrast to ATM kinase inhibitor KU55933, which completely blocked the Chk2 kinase phosphorylation on threonine 68, and ATR kinase inhibitor VE-821, which blocked the Chk1 kinase phosphorylation on serine 345...

ROGDI is a protein that contains a leucine zipper domain and may be involved in cell proliferation. In addition, ROGDI is associated with genome stability by regulating the activity of a DNA damage marker, γ-H2AX. The role of ROGDI in tumor radiosensitization has not been investigated. Previous studies have indicated that radiosensitivity is associated with DNA repair and the cell cycle. In general, the G2/M DNA damage checkpoint is more sensitive to radiation, whereas the G1/S phase transition is more resistant to radiation...
