Fibroma osificante periférico: presentación de tres casos y revisión de la literatura

El fibroma osificante periférico (FOP) es una entidad benigna que se incluye en el grupo de las lesiones gingivales reactivas, denominadas con el término genérico de épulis, y se origina, según la teoría más aceptada, en las células del ligamento periodontal. Se manifiesta en forma de tumoración de consistencia firme, bien circunscrita, de color rosado o rojizo y está situada normalmente en la zona incisivo-canina del maxilar superior, siendo rara su aparición en crestas edéntulas. Aparece a cualquier edad, con una mayor incidencia entre la segunda y tercera décadas de la vida, con una ligera predilección por el sexo femenino. Es una lesión de partes blandas, que en ocasiones puede estar asociada a una ligera erosión superficial del hueso subyacente. Se han revisado 3 casos de FOP que afectaban a 2 hombres y 1 mujer de edades comprendidas entre los 39 y los 73 años, presentándose uno de ellos en una cresta alveolar edéntula. En dos casos se observaba radiográficamente una ligera erosión del hueso subyacente y el tercer caso presentaba puntos radioopacos difusos intralesionales. El tratamiento consistió en realizar la exéresis-biopsia de las lesiones, efectuándose dos casos mediante bisturí frío y uno con láser de CO2. Uno de los casos presentó tres episodios de recidiva en el seguimiento postoperatorio

Long-term outcomes of oral rehabilitation with dental implants in HIV-positive patients: A retrospective case series

Background: The existing information on oral rehabilitations with dental implants in VIH-positive patients is scarce and of poor quality. Moreover, no long-term follow-up studies are available. Hence, the aims of this study were to describe the long-term survival and success rates of dental implants in a group of HIV-positive patients and to identify the most common postoperative complications, including peri-implant diseases. Material and Methods: A retrospective case series of HIV-positive subjects treated with dental implants at the School of Dentistry of the University of Barcelona (Spain) was studied. Several clinical parameters were registered, including CD4 cell count, viral load and surgical complications. Additionally, the patients were assessed for implant survival and success rates and for the prevalence of peri-implant diseases. A descriptive statistical analysis of the data was performed. Results: Nine participants (57 implants) were included. The patients' median age was 42 years (IQR= 13.5 years). The implant survival and success rates were 98.3% and 68.4%, respectively, with a mean follow-up of 77.5 months (SD= 16.1 months). The patient-based prevalence of peri-implant mucositis and peri-implantitis were 22.2% and 44.4% respectively at the last appointment. Patients that attended regular periodontal maintenance visits had significantly less mean bone loss than non-compliant patients (1.3 mm and 3.9 mm respectively). Conclusions: Oral rehabilitation with dental implants in HIV-positive patients seems to provide satisfactory results. In order to reduce the considerably high prevalence of peri-implant diseases, strict maintenance programmes must be implemented

Reproductive desire in women with HIV infection in Spain, associated factors and motivations: A mixed-method study

Background: Antiretroviral therapy has created new expectations in the possibilities of procreation for persons living with HIV. Our objectives were to evaluate reproductive desire and to analyze the associated sociodemographic and clinical factors in HIV-infected women in the Spanish AIDS Research Network Cohort (CoRIS).Methods: A mixed qualitative-quantitative approach was designed. Women of reproductive age (18-45) included in CoRIS were interviewed by phone, and data were collected between November 2010 and June 2012 using a specifically designed questionnaire. Reproductive desire was defined as having a desire to be pregnant at present or having unprotected sex with the purpose of having children or wanting to have children in the near future.Results: Overall, 134 women were interviewed. Median age was 36 years (IQR 31-41), 55% were Spanish, and 35% were unemployed. 84% had been infected with HIV through unprotected sex, with a median time since diagnosis of 4.5 years (IQR 2.9-6.9). Reproductive desire was found in 49% of women and was associated with: 1) Age (women under 30 had higher reproductive desire than those aged 30-39; OR = 4.5, 95% CI 1.4-14.3); 2) having no children vs. already having children (OR = 3.2; 1.3-7.7 3); Being an immigrant (OR = 2.2; 1.0-5.0); and 4) Not receiving antiretroviral treatment (OR = 3.6; 1.1-12.1). The main reasons for wanting children were related to liking children and wanting to form a family. Reasons for not having children were HIV infection, older age and having children already. Half of the women had sought or received information about how to have a safe pregnancy, 87% had disclosed their serostatus to their family circle, and 39% reported having experienced discrimination due to HIV infection.Conclusions: The HIV-infected women interviewed in CoRIS have a high desire for children, and the factors associated with this desire are not fundamentally different from those of women in the general population. Maternity may even help them face a situation they still consider stigmatized and prefer not to disclose. Health-care protocols for handling HIV-positive women should incorporate specific interventions on sexual and reproductive health to help them fulfill their procreation desire and experience safe pregnanciesThe RIS cohort (CoRIS) is funded by the Instituto de Salud Carlos III through the Red Temática de Investigación Cooperativa en Sida (RIS C03/173

Se expone una revisión de la literatura científica publicada en revistas indexadas durante el año 2007 sobre Implantología Bucofacial. La escasez de tiempo de que disponen los profesionales para consultar las múltiples fuentes de información, ha motivado a los autores a resumir los artículos publicados y clasificarlos en los siguientes apartados: generalidades, pacientes especiales, superficies y diseños, tejidos blandos, implantes inmediatos, carga inmediata, complicaciones, elevación sinusal, técnicas avanzadas, plasma rico en plaquetas y factores de crecimiento, cirugía guiada, cirugía mínimamente invasiva y miniimplantes, con la intención de facilitar una puesta al día

A global experiment on motivating social distancing during the COVID-19 pandemic

Finding communication strategies that effectively motivate social distancing continues to be a global public health priority during the COVID-19 pandemic. This cross-country, preregistered experiment (n = 25,718 from 89 countries) tested hypotheses concerning generalizable positive and negative outcomes of social distancing messages that promoted personal agency and reflective choices (i.e., an autonomy-supportive message) or were restrictive and shaming (i.e., a controlling message) compared with no message at all. Results partially supported experimental hypotheses in that the controlling message increased controlled motivation (a poorly internalized form of motivation relying on shame, guilt, and fear of social consequences) relative to no message. On the other hand, the autonomy-supportive message lowered feelings of defiance compared with the controlling message, but the controlling message did not differ from receiving no message at all. Unexpectedly, messages did not influence autonomous motivation (a highly internalized form of motivation relying on one’s core values) or behavioral intentions. Results supported hypothesized associations between people’s existing autonomous and controlled motivations and self-reported behavioral intentions to engage in social distancing. Controlled motivation was associated with more defiance and less long-term behavioral intention to engage in social distancing, whereas autonomous motivation was associated with less defiance and more short- and long-term intentions to social distance. Overall, this work highlights the potential harm of using shaming and pressuring language in public health communication, with implications for the current and future global health challenges

A multi-country test of brief reappraisal interventions on emotions during the COVID-19 pandemic.

The COVID-19 pandemic has increased negative emotions and decreased positive emotions globally. Left unchecked, these emotional changes might have a wide array of adverse impacts. To reduce negative emotions and increase positive emotions, we tested the effectiveness of reappraisal, an emotion-regulation strategy that modifies how one thinks about a situation. Participants from 87 countries and regions (n = 21,644) were randomly assigned to one of two brief reappraisal interventions (reconstrual or repurposing) or one of two control conditions (active or passive). Results revealed that both reappraisal interventions (vesus both control conditions) consistently reduced negative emotions and increased positive emotions across different measures. Reconstrual and repurposing interventions had similar effects. Importantly, planned exploratory analyses indicated that reappraisal interventions did not reduce intentions to practice preventive health behaviours. The findings demonstrate the viability of creating scalable, low-cost interventions for use around the world
