RESUMO
El Tumor odontogénico adenomatoide (TOA), es un tumor poco común, benigno, no invasivo, que representa el 3% de todos los tumores odontogénicos y presenta las si- guientes variantes: folicular, extrafolicular y periférica, siendo la más común la folicular asociada a un diente incluido. El objetivo de este artículo es presentar un caso de TOA extrafolicular en paciente femenino de 13 años de edad, localizado a nivel de la región del canino superior izquierdo. Al examen extraoral se observó tumefacción leve, ocasio- nando pérdida de definición del pliegue nasolabial izquierdo; a la evaluación intraoral, se observó tumefacción a nivel de los elementos dentarios 2.2 y 2.3 con desplazamiento de los mismos, ocasionando diastema; en el examen tomográfico se identificó una imagen hipodensa con bordes hiperdensos bien definidos, con calcificaciones internas. Se realizó biopsia incisional, que resultó como diagnóstico TOA extrafolicular y se procedió a la enucleación del tumor. En un seguimiento de 24 meses, fue posible observar regenera- ción ósea sin señales de recidiva.
Odontogenic adenomatoid tumor (OAT), is a rare, benign, non-invasive, represents 3% of all odontogenic tumors. It presents follicular, extrafollicular and peripheral variants, the follicular variant with an included tooth is the most common. The objective of this article is to present a case of TOA in a 13-year-old female patient, located in the upper left canine region. After extrabuccal examination, slight swelling was observed, causing loss of definition of the left nasolabial fold, on intrabuccal examination, swelling of the vestibular bone table was observed between elements 2.2 and 2.3 with dislocation of the same, causing diastema, the tomographic examination identifies hypodense image with well-defined hyperdense borders, with internal calcifications. Incisional biopsy was performed, which resulted as diagnosis an extrafollicular TOA. The enucleation of the tumor was proceeded. In a 24-month follow-up, it is possible to observe bone regenera- tion without signs of recurrence.
RESUMO
The objective of this study was to evaluate the genetic and environmental contribution to variation in aerobic power in monozygotic (MZ) and dizygotic (DZ) twins. The sample consisted of 20 MZ individuals (12 females and 8 males) and 16 DZ individuals (12 females and 4 males), aged from 8 to 26 years, residents in Natal, Rio Grande do Norte. The twins were assessed by a multistage fitness test. The rate of heritability found for aerobic power was 77%. Based on the results, the estimated heritability was largely responsible for the differences in aerobic power. This implies that such measures are under strong genetic influence.
RESUMO
Obstructive sleep apnoea syndrome (OSAS) often coexists in patients with chronic obstructive pulmonary disease (COPD). The present prospective cohort study tested the effect of OSAS treatment with continuous positive airway pressure (CPAP) on the survival of hypoxaemic COPD patients. It was hypothesised that CPAP treatment would be associated with higher survival in patients with moderate-to-severe OSAS and hypoxaemic COPD receiving long-term oxygen therapy (LTOT). Prospective study participants attended two outpatient advanced lung disease LTOT clinics in São Paulo, Brazil, between January 1996 and July 2006. Of 603 hypoxaemic COPD patients receiving LTOT, 95 were diagnosed with moderate-to-severe OSAS. Of this OSAS group, 61 (64%) patients accepted and were adherent to CPAP treatment, and 34 did not accept or were not adherent and were considered not treated. The 5-yr survival estimate was 71% (95% confidence interval 53-83%) and 26% (12-43%) in the CPAP-treated and nontreated groups, respectively (p<0.01). After adjusting for several confounders, patients treated with CPAP showed a significantly lower risk of death (hazard ratio of death versus nontreated 0.19 (0.08-0.48)). The present study found that CPAP treatment was associated with higher survival in patients with moderate-to-severe OSAS and hypoxaemic COPD receiving LTOT.
