Caliber-persistent Artery: A Case Report

2019

ABSTRACT The caliber-persistent labial artery (CPLA) is a vascular anomaly in which a main branch of the artery penetrates the submucosal area of the lip without loss of caliber. It commonly presents as an elevated soft tissue mass and is often pulsatile on manual palpation. Clinical suspicion is important, given the risk of bleeding, either from slight trauma or accidentally if lack of awareness leads to excision of the lesion owing to an incorrect diagnosis. CPLA should be considered in the differential diagnosis of any lesion affecting the lip, especially to differentiate from mucocele or squamous cell carcinoma. This particular case of CPLA in the upper lip of a girl presents a both unu…

Erratum: Melanoma Unknown Primary Brain Metastasis Treatment With ECHO-7 Oncolytic Virus Rigvir: A Case Report

2018

Melanoma is considered an aggressive malignancy with a tendency of forming metastasis in the brain. Less than 10% of all melanoma cases present with unknown primary tumor location. This diagnose is yet to be fully understood, because there are only theoretical assumptions about the nature of the disease. Melanoma brain metastases have many severe side effects and, unfortunately, any disease related to the brain has limited therapeutic options due to the blood–brain barrier. The course of the disease after a treatment course is complicated to predict, and it is difficult to obtain long-lasting remission. In this report, we describe a female patient with unknown primary melanoma brain metasta…

Cancer stem cell definitions and terminology:the devil is in the details

2012

The cancer stem cell (CSC) concept has important therapeutic implications, but its investigation has been hampered both by a lack of consistency in the terms used for these cells and by how they are defined. Evidence of their heterogeneous origins, frequencies and their genomic, as well as their phenotypic and functional, properties has added to the confusion and has fuelled new ideas and controversies. Participants in The Year 2011 Working Conference on CSCs met to review these issues and to propose a conceptual and practical framework for CSC terminology. More precise reporting of the parameters that are used to identify CSCs and to attribute responses to them is also recommended as key t…

Negative transcriptional control of ERBB2 gene by MBP-1 and HDAC1: diagnostic implications in breast cancer

2013

Abstract Background The human ERBB2 gene is frequently amplified in breast tumors, and its high expression is associated with poor prognosis. We previously reported a significant inverse correlation between Myc promoter-binding protein-1 (MBP-1) and ERBB2 expression in primary breast invasive ductal carcinoma (IDC). MBP-1 is a transcriptional repressor of the c-MYC gene that acts by binding to the P2 promoter; only one other direct target of MBP-1, the COX2 gene, has been identified so far. Methods To gain new insights into the functional relationship linking MBP-1 and ERBB2 in breast cancer, we have investigated the effects of MBP-1 expression on endogenous ERBB2 transcript and protein lev…

Carcinosarcoma of monoclonal origin arising in a dermoid cyst of ovary: a case report.

2005

Abstract Background Transformation of a cystic benign teratoma of the ovary into a "carcinosarcoma" has very rarely been reported and its histogenetic origin is still debated. Case presentation A case of carcinosarcoma arising from a dermoid cyst is reported. The tumor showed cystic areas delimited by normal squamous epithelium, with transitional areas through dysplastic epithelium to "in situ" and infiltrating squamous cell carcinoma (SCC). The sarcomatous component showed compact tissue composed of round cells concentrically arranged around small vessels, spindle, and pleomorphic cells with a high nuclear-cytoplasmic ratio. Positive staining for vimentin, alpha smooth muscle actin and CD1…

Overexpression of Ogg1 in mammalian cells: effects on induced and spontaneous oxidative DNA damage and mutagenesis

1999

Chinese hamster ovary cell lines (AA8 and AS52) were stably transfected to overexpress hOgg1 protein, the human DNA repair glycosylase for 7,8-dihydro-8-oxoguanine (8-oxoG). In the transfectants, the repair rate of 8-oxoG residues induced by either potassium bromate or the photosensitizer [R]-1-[(10-chloro-4-oxo-3-phenyl-4H-benzo[a]quinolizin-1-yl)-carbo nyl ]-2-pyrrolidinemethanolplus light was up to 3-fold more rapid than in the parental cells. However, the improved repair had little effect on the mutagenicity of potassium bromate in the guanine phosphoribosyl transferase (gpt) locus of the OGG1-transfected AS52 cells. The steady-state (background) levels of DNA base modifications sensiti…

pap, reg I? andreg I? mRNAs are concomitantly up-regulated during human colorectal carcinogenesis

1999

We have established the phenotype of a colorectal tumor by partial sequencing of 2166 transcripts that were eventually arrayed on high-density filters. These filters were used for differential screening with mRNAs of colorectal cancer and normal adjacent mucosa to characterize genes whose expression is altered in colorectal carcinoma. Three genes encoding related proteins, PAP, reg Iα and reg Iβ, were over-expressed in cancer. Northern-blot analysis confirmed that their expression was very low in normal colonic epithelial cells, but elevated in 75% of tumors. Western blotting with specific antibodies to pap and reg Iα revealed in tumors a single band of the expected size (15–16 kDa), demons…

Sexual, bladder and bowel function following different minimally invasive techniques of radical hysterectomy in patients with early-stage cervical ca…

2021

Abstract Purpose Despite the establishment of radical surgery for therapy of cervical cancer, data on quality of life and patient-reported outcomes are scarce. The aim of this retrospective cohort study was to evaluate bladder, bowel and sexual function in women who underwent minimally invasive surgery for early-stage cervical cancer. Methods From 2007–2013, 261 women underwent laparoscopically assisted radical vaginal hysterectomy (LARVH = 45), vaginally assisted laparoscopic or robotic radical hysterectomy (VALRRH = 61) or laparoscopic total mesometrial resection (TMMR = 25) and 131 of them completed the validated German version of the Australian Pelvic Floor Questionnaire (PFQ).
