Ghost cell odontogenic carcinoma: a rare case report and review of literature
2014
Objectives: Ghost cell odontogenic carcinoma is a rare condition characterized by ameloblastic-like islands of epithelial cells with aberrant keratinitation in the form of Ghost cell with varying amounts of dysplastic dentina. Material and Methods: We report a case of a 70 year-old woman with a rapid onset of painful swelling right maxillary tumor. Magnetic resonance showed a huge tumor dependent on the right half of the right hard palate with invasion of the pterygoid process and focally to the second branch of the trigeminal. Radiological stage was T4N0. The patient underwent a right subtotal maxillectomy with clear margins. Adjuvant radiotherapy was given. The patient was free of residua…
Whole-body magnetic resonance for staging and response assessment of lymphoma in a pregnant woman treated with antenatal chemotherapy
2017
A 32-year-old pregnant female presented with bilateral supraclavicular swelling, diffuse itching and right shoulder pain. After lymph nodal biopsy, a diagnosis of nodular sclerosis Hodgkin's lymphoma was obtained. A multidisciplinary team decided to start chemotherapy before the delivery, and whole-body MRI was used to stage the disease and evaluate the response after antenatal chemotherapy. This case shows that whole-body MRI is an attractive procedure that avoids radiation exposure and contrast administration, and enables staging and follow-up of a pregnant patient without risk to the fetus.
Use of bone scintigraphy in the early diagnosis of bisphosphonate related osteonecrosis of the jaw. Case report and review of the literature
2018
The main aim of the present report is to show the potential utility of bone scintigraphy for the diagnosis of jaw osteonecrosis. We report the history of a 62-year-old woman underwent breast cancer surgery in 2010. Moreover, patient received postoperative radiotherapy and chemotherapy. Intravenous bisphosphonates were also added to the treatment strategy to reduce the risk of bone metastasis. However, a hypermetabolic focus on left hemimandible was evidenced with a bone scintigraphy during follow up. After a careful study, the diagnosis of Bisphosphonate Related Ostneonecrosis of the Jaw (BRONJ) was carried out. This case highlights that bone scintigraphy may be extremely helpful for the ea…
Perceived neighborhood social disorder and residents' attitudes toward reporting child physical abuse.
2004
OBJECTIVE: This study aimed to explore the relationship between perceived neighborhood social disorder and attitudes toward reporting child physical abuse. METHOD: Data from a national probabilistic sample (N=9,759) were used. Responses about the perception of neighborhood social disorder, perceived frequency of child physical abuse in Spanish families, and willingness to report a case of child physical abuse to the police were collected through face-to-face interviews in respondents' homes. RESULTS: Multivariate logistic regression analysis showed that perceived neighborhood social disorder was negatively related to residents' attitudes toward reporting child physical abuse. These results …
Walking Children Through a Minefield: How Professionals Experience Exploring Adverse Childhood Experiences
2017
Understanding the challenges of professionals in addressing child adversity is key to improving the detection, protection, and care of exposed children. We aimed to synthesize findings from qualitative studies of professionals’ lived experience of addressing child adversity. Through a systematic search, we identified eight qualitative studies and synthesized them using metaethnography. We generated three themes, “feeling inadequate,” “fear of making it worse,” and “facing evil,” and one overarching metaphor, “walking children through a minefield.” The professionals felt that they lacked the means necessary to explore child adversity, that they were apprehensive of worsening the child’s situ…

Macroeconomic determinants of Peruvian migration flows
2020
The objective of this paper is to determine the variables associated with the weight that Peruvian immigration has in the total immigration in Chile for the period 2005-2014. The initial hypothesis is that the Peruvian migratory flow has a social and economic component. The results showed that an increase in the Human Development Index (HDI) in favor of Chile increases the migratory flow. On the other hand, a larger education budget in favor of Chile decreases the migratory flow of Peruvian citizens.
De-epoxidation of Violaxanthin in Light-harvesting Complex I Proteins
2004
The conversion of violaxanthin (Vx) to zeaxanthin (Zx) in the de-epoxidation reaction of the xanthophyll cycle plays an important role in the protection of chloroplasts against photooxidative damage. Vx is bound to the antenna proteins of both photosystems. In photosystem II, the formation of Zx is essential for the pH-dependent dissipation of excess light energy as heat. The function of Zx in photosystem I is still unclear. In this work we investigated the de-epoxidation characteristics of light-harvesting complex proteins of photosystem I (LHCI) under in vivo and in vitro conditions. Recombinant LHCI (Lhcal-4) proteins were reconstituted with Vx and lutein, and the convertibility of Vx wa…
Endogenous fluctuations of DNA topology in the chloroplast of Chlamydomonas reinhardtii.
1998
DNA supercoiling in the chloroplast of the unicellular green alga Chlamydomonas reinhardtii was found to change with a diurnal rhythm in cells growing in alternating 12-h dark-12-h light periods. Highest and lowest DNA superhelicities occurred at the beginning and towards the end of the 12-h light periods, respectively. The fluctuations in DNA supercoiling occurred concurrently and in the same direction in two separate parts of the chloroplast genome, one containing the genes psaB, rbcL, and atpA and the other containing the atpB gene. Fluctuations were not confined to transcribed DNA regions, indicating simultaneous changes in DNA conformation all over the chloroplast genome. Because the d…
Interference-Based Chromatic Coatings by Ion Plating Plasma Assisted Deposition Technology
2010
The goal of replacing widespread and inexpensive galvanic treatments with suitable vacuum deposition techniques, in order to eliminate the environmental hazards and their polluting effects, is becoming, in some cases, more tangible. Shorter cleaning cycles, shorter pump-down times, reduced heating times of substrates and higher deposition rates allow the costs of new plasma-assisted processes to become competitive with respect to galvanic ones. Moreover, vacuum treatments offer superior mechanical and optical properties and non-conductive substrates (like glass, ceramics, plastics) can be more easily coated. This work describes the results obtained with Ion Plating Plasma Assisted depositio…
