Cancer incidence rate ratios of Turkish immigrants in Hamburg, Germany: A registry based study
2009
The aim of this Study was to estimate cancer incidence rate ratios for Turkish migrants in Hamburg, Germany. We used a name-based approach and identified 1346 cases with Turkish names (as a proxy of Turkish origin) among 140,249 cases of cancer registered in the cancer registry Hamburg during 1990-2005. To estimate the size of the denominator population, we applied the name-based approach to the population of Hamburg as well. The cancer incidence of specific cancer sites was compared between Turkish and non-Turkish cases using incidence rate ratios (IRR), stratified by gender and birth cohort. Our main findings are that cancer of the respiratory organs is diagnosed less frequent among Turki…
Parental occupational exposure to organic solvents and anencephaly in Mexico
2009
Objective: To assess the relationship between parental occupational exposure to organic solvents, and the risk of anencephaly in Mexico. Methods: A case-control study was conducted based on the registers of the Epidemiological Surveillance System for Neural Tube Defects in Mexico; 151 cases of anencephaly of ≥20 weeks’ gestation were included. A control, born alive and without any apparent congenital malformations at birth, was selected for each case in the same maternity service in which the case was born. Information on occupational exposures, lifestyle habits, reproductive history, use of medicines, supplementation with multivitamins and folic acid, was obtained by a general questionnair…
Treatment of chronic mandibular dislocations by eminectomy: follow-up of 10 cases and literature review.
2008
Introduction: Temporomandibular joint (TMJ) dislocation is defined as an excessive forward movement of the condyle beyond the articular eminence, with complete separation of the articular surfaces and fixation in that position. Objectives: To report ten cases treated by eminectomy for chronic mandibular dislocations, to evaluate the results of these surgeries and make a critical review of the literature. Methods: The sample was obtained from the records of the Department of Oral and Maxillofacial Surgery, University of Pernambuco and comprises cases submitted to chronic mandibular dislocation treatment by eminectomy between 2002 and 2007. Pre- and postoperative assessment included a thoroug…
Results of closed subtalar dislocations.
2015
Background The subtalar dislocation (SD) of the foot is an uncommon injury characterized by a simultaneous dislocation of talocalcaneal and talonavicular joints without involvement of the tibiotalar and calcaneocuboid joints. Purposes The purpose of this study was to evaluate the clinical and radiological outcome in a consecutive series of close SD. Methods We retrospectively evaluated a case series of patients who presented a close SD. Thirteen patients were selected for this study. There were 9 patients with a medial SD, 3 patients with a lateral dislocation and 1 patient with a posterior subtalar dislocation. Results The most frequent symptoms observed in our study included transient mil…
Traumatic atlanto-axial rotatory subluxation after surgical correction of prominent ears: Case report and review of the literature
2019
International audience; Corrective surgery of prominent ears may be justified for social or aesthetic reasons during childhood or adulthood. Post-operative complications occur in approximately 0 to 8.4% of cases. This case describes a rare atlanto-axoid rotatory subluxation after bilateral surgical correction of prominent ears under general anesthesia. Orthopedic treatment was done after two months of medical roaming outside of our center. The one-year post-operative clinic consultation and radiological exam were normal. Only the psychological impact of the episode remained. Traumatic atlanto-axial rotatory subluxation is a rare complication but should be considered after post-operative tor…
Efficacy of eminectomy in the treatment of prolonged mandibular dislocation
2009
Surgery of the temporomandibular joint is indicated for different clinical situations, including internal derangements, hipomobility, hipermobility, pathology and trauma. Mandibular dislocation is an acute painful condition that causes severe functional limitation. Manual reduction, with or without pharmacological assistance, is the treatment of choice and should be performed as early as possible. On rare situations mandibular dislocation may not be perceived by the patient and remain undiagnosed or misdiagnosed for a long period. This may include severe illness, neurological diseases and prolonged intensive care hospitalization with oral intubation and sedation. Treatment of prolonged mand…
Robust consensus in social networks and coalitional games
2014
We study an n-player averaging process with dynamics subject to controls and adversarial disturbances. The model arises in two distinct application domains: i) coalitional games with transferable utilities (TU) and ii) opinion propagation. We study conditions under which the average allocations achieve robust consensus to some predefined target set.
Simplification, not “tropicalization”, of temperate marine ecosystems under ocean warming and acidification
2021
Ocean warming is altering the biogeographical distribution of marine organisms. In the tropics, rising sea surface temperatures are restructuring coral reef communities with sensitive species being lost. At the biogeographical divide between temperate and tropical communities, warming is causing macroalgal forest loss and the spread of tropical corals, fishes and other species, termed “tropicalization”. A lack of field research into the combined effects of warming and ocean acidification means there is a gap in our ability to understand and plan for changes in coastal ecosystems. Here, we focus on the tropicalization trajectory of temperate marine ecosystems becoming coral-dominated systems…
Climate change and the ecology and evolution of Arctic vertebrates.
2012
25 pages; International audience; Climate change is taking place more rapidly and severely in the Arctic than anywhere on the globe, exposing Arctic vertebrates to a host of impacts. Changes in the cryosphere dominate the physical changes that already affect these animals, but increasing air temperatures, changes in precipitation, and ocean acidification will also affect Arctic ecosystems in the future. Adaptation via natural selection is problematic in such a rapidly changing environment. Adjustment via phenotypic plasticity is therefore likely to dominate Arctic vertebrate responses in the short term, and many such adjustments have already been documented. Changes in phenology and range w…
Olfactory attraction of the hornet Vespa velutina to honeybee colony odors and pheromones.
2014
19 pages; International audience; Since the beginning of the last century, the number of biological invasions has continuously increased worldwide. Due to their environmental and economical consequences, invasive species are now a major concern. Social wasps are particularly efficient invaders because of their distinctive biology and behavior. Among them, the yellow-legged hornet, Vespa velutina, is a keen hunter of domestic honeybees. Its recent introduction to Europe may induce important beekeeping, pollination, and biodiversity problems. Hornets use olfactory cues for the long-range detection of food sources, in this case the location of honeybee colonies, but the exact nature of these c…
