Neoadjuvant chemotherapy plus radical surgery in locally advanced cervical cancer during pregnancy: a case report
Management of cervicocarcinoma during pregnancy is influenced by gestational age, stage of disease, and patient's desire to maintain her pregnancy. We report a case of a pregnant patient with locally advanced cervicocarcinoma successfully treated by neoadjuvant chemotherapy, followed by caesarean section and radical surgery
Late breast cancer recurrence to the uterine cervix with a review of the literature
The cervix is a possible site of metastasis from any primary malignancy,but no specific indication on follow-up examination is present. We present an asymptomatic patient with isolated breast cancer cervical recurrence diagnosed by colposcopy after 11 years from primary disease. After a PubMed search and a review of current guidelines, no indication to follow-up examination regarding the cervix is present. The adoption of colposcopy in cancer survivors might be an aid to gynecologists in diagnosing cancer recurrence. Cancer survivors might benefit from a more thorough gynecologic examination as compared with the simple Papanicolaou test. Key Words: Breast cancer—Colposcopy—Uterine cervix recurrence
Ovarian cancer, diagnosed with PET, with bilateral inguinal lymphadenopathy as primary presenting sign
Ovarian cancer groin lymph nodes metastases are rare. Only one case of disease spread isolated to the groins has been reported in the English literature. We report the case of a patient with bilateral inguinal lymphadenopathy due to tumor metastases and in which tumor origin was diagnosed using [(18)F]fluorodeoxyglucose positron emission tomography (PET). This is the first case of bilateral groin lymph nodes as sole site of metastases from ovarian cancer. Primary origin was identified using PET. In rare cases, the ovaries can directly metastasis to the groin even in a relatively initial tumor growth phase. PET may play a role in the diagnosis of occult ovarian tumors
ASSESSING MYOMETRIAL INVASION IN ENDOMETRIAL CANCER: IS THREE DIMENSIONAL RECONSTRUCTION MORE USEFUL FOR NON-EXPERT SCAN OPERATORS?
Intraperitoneal chemotherapy by ultrasound-guided direct puncture in recurrent ovarian cancer: feasibility, compliance, and complications.
Objective: This prospective pilot study investigated the feasibility, complications, and compliance of the administration of intraperitoneal (IP) chemotherapy by direct puncture under ultrasonographic guidance performed on consecutive patients with recurrent ovarian cancer (ROC). Methods: Patients were evaluated to undergo secondary cytoreduction and/or to receive IP chemotherapy. Patients received standard intravenous therapy for ROC plus IP administration by direct puncture needle, under ultrasonographic guidance. Results: From January 2008 to January 2011, 38 patients were enrolled. A total of 402 IP procedures were performed, with a mean of 10.5 procedures per patient. The feasibility rate was 97.4%. In 237 cases (98.8%) of subgroup 1 (abdominal wall thickness 6 cm), more than 1 attempt was necessary (P < 0.01). The mean procedure time was 10 minutes (range, 5-30 minutes). We recorded a total of 2.25% mild intraprocedure complications. No significant difference was identified for the complication rate according to the abdominal wall thickness or according to the number of previous laparotomies. A total of 5 procedures (1.2%) were not performed as a result of patients' noncompliance. The mean pain score according to the visual analog pain scale was moderate at the first evaluation (after 3 minutes) and mild at the final evaluation (after 10 minutes). Conclusions: The administration of IP chemotherapy with a direct puncture, under ultrasound guidance, for patients with ROC, is a safe and feasible method, with a high acceptance from patients
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
