Multiple Papillomavirus Infection and Size of Colposcopic Lesions among Women with Cervical Intraepithelial Neoplasia
No full textObjective The aim of the study was to evaluate the association between the size of cervical lesions as detected by colposcopy and multiple human papillomavirus (HPV) infection in subjects with cervical intraepithelial neoplasia (CIN). Methods A case series of 898 subjects with CIN diagnosed by histopathology and infected by high-risk HPV. Human papillomavirus genotypes were identified using the INNO-LIPA genotyping system. Results The rates of CIN 1, CIN 2, and CIN 3+ lesions were 53.1% (477/898), 14.1% (127/898), and 32.7% (294/898), respectively. Among CIN lesions diagnosed by loop electrosurgical excision procedure or by cold-knife conization, the rates of multiple as compared with single HPV infections increased from 31.7% (59/186) in lesions covering 0% to 25% of the cervix to 39.2% (40/102), 41.9% (13/31), and 48.9% (45/92) in those covering 26% to 50%, 51% to 75%, and more than 75% of the cervix, respectively (Ï2 for trend = 7.9; p =.005). In ordered logistic regression, after correction for confounders, odds ratios (ORs) of larger cervical lesions were higher in multiple as compared with single infections (OR = 1.82; 95% CI = 1.24-2.66; p =.002). This association was confirmed among subjects infected by HPV 16 (OR = 2.45; 95% CI = 1.14-5.26; p =.02) and in CIN 3+ lesions (OR = 2.43; 95% CI = 1.23-4.80; p =.01). Conclusions Multiple high-risk HPV infection is associated with larger cervical lesions as detected by colposcopy. This association was confirmed among subjects infected by HPV 16 and in CIN 3+ lesions
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Juvenile Granulosa Cell Tumor of the Testis: Prenatal Diagnosis and Management
No full textPrepubertal primary testicular tumors account for ∼1% of all pediatric solid tumors. We report a new case of prenatal diagnosis of juvenile-type granulosa cell tumor (JGCT). A fetal ultrasound performed at the 38th week of gestation for suspected nonvertex presentation identified a left multilocular septated cystic testicular mass, suggestive for JGCT. At birth, a painless left scrotal mass was detected. Ultrasound re-evaluation excluded torsion of the testis. Tumor markers and abdominal ultrasound were normal for age. Inguinal exploration revealed a cystic mass beneath the tunica albuginea that had replaced all the normal parenchyma. Since organ-sparing surgery was thus not feasible, an orchiectomy was performed and diagnosis of JGCT was confirmed. At 7-year follow-up, the child presented an uneventful outcome. Our case shows that neonatal JGCT, which has an intrauterine genesis, can be diagnosed prenatally by ultrasound in the last weeks of pregnancy
Apoptosis-related proteins and cervical intraepithelial neoplasia in human immunodeficiency virus-seropositive women
No full textVariations on the Author
Full text link“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
Outcome of Persistent Low-Grade Cervical Intraepithelial Neoplasia Treated With Loop Electrosurgical Excision Procedure
No full textWhat is known about neuroplacentology in fetal growth restriction and in preterm infants: A narrative review of literature
Full text linkThe placenta plays a fundamental role during pregnancy for fetal growth and development. A suboptimal placental function may result in severe consequences during the infant’s first years of life. In recent years, a new field known as neuroplacentology has emerged and it focuses on the role of the placenta in fetal and neonatal brain development. Because of the limited data, our aim was to provide a narrative review of the most recent knowledge about the relation between placental lesions and fetal and newborn neurological development. Papers published online from 2000 until February 2022 were taken into consideration and particular attention was given to articles in which placental lesions were related to neonatal morbidity and short-term and long-term neurological outcome. Most research regarding the role of placental lesions in neurodevelopment has been conducted on fetal growth restriction and preterm infants. Principal neurological outcomes investigated were periventricular leukomalacia, intraventricular hemorrhages, neonatal encephalopathy and autism spectrum disorder. No consequences in motor development were found. All the considered studies agree about the crucial role played by placenta in fetal and neonatal neurological development and outcome. However, the causal mechanisms remain largely unknown. Knowledge on the pathophysiological mechanisms and on placenta-related risks for neurological problems may provide clues for early interventions aiming to improve neurological outcomes, especially among pediatricians and child psychiatrists
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe 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
