Prevalence of morphological and structural changes in the stylohyoid chain

2020

Background Total or partial calcification of the stylohyoid chain, elongation of the stylohyoid process of the temporal bone and/or calcification of the stylohyoid ligament are usually incidental radiographic findings. The purpose of this study was to evaluate the prevalence of morphological and structural changes within the stylohyoid chain in 4413 digital panoramic radiographs. Material and methods The images were evaluated for the presence or absence of changes in the stylohyoid chain by a specialist in dentofacial radiology and the information collected comprised gender, age, side, right and left measurements and classification of the chain side elongated or calcified stylohyoid process…

Improved orbital parameters of accreting millisecond pulsar SAX J1808.4-3658

2006

Abstract We analyze the three outbursts of the X-ray millisecond pulsar SAX J1808.4-3658 that occurred in 1998, 2000, and 2002 observed with RXTE. With a technique based on epoch folding search we find an unique orbital solution valid over the five years of high temporal resolution data available. We revise the estimate of the orbital period, P orb  = 7249.1569(1) s and of its error, which we decrease by one order of magnitude. We also give the first constraint on the orbital period derivative, - 6.6 × 10 - 12 P ˙ orb + 0.8 × 10 - 12 s s - 1 . We find that in 2002 the pulse profile shape is clearly asymmetric, showing a secondary peak at about 145° from the main pulse, which is different fr…

Understanding the role of osteoarthrosis on electromyographic activity of masticatory muscles and quality of life

2019

Background Osteoarthrosis is a severe, evolutionary, chronic, and limiting disease that influences on quality of life, as it affects synovial joints and promoted degradation of hyaline articular cartilage. We sought to determine if electromyographic activity of the masticatory muscles and quality of life are negatively impacted by osteoarthrosis. Material and Methods A sample of 72 participants between 40 and 70 years old diagnosed with osteoarthrosis were selected. Forty-eight participants met the inclusion criteria of this study and were divided into two distinct groups: with osteoarthrosis (n=24) and without osteoarthrosis (n=24). Electromyographic activity of the masseter and temporalis…

Death by Facial and Skull Injuries of a Motorcyclist Wearing a Full-Face Helmet: Case Report and Literature Review

2016

We describe a case of death by facial and skull fractures with brain injuries of a motorcyclist wearing a full-face helmet. A 40-year-old man driving a high-powered motorcycle crashed violently into the rear of a stopped car. The main results from the autopsy revealed the deformation of the left orbito-zygomatic and fronto-temporoparietal regions corresponding to bone fractures with laceration at the left temporal lobe. The CT scan of the helmet revealed the detachment of the energy-absorbing liner. Moreover an impact speed of 93 Km/h resulted from the analysis of accident dynamics. We analysed the literature regarding the effectiveness of full-face helmets in reducing the risk of fatality …

Jacob's disease secondary to coronoid process osteochondroma. A case report

2010

The formation of a new joint between a pathologically elongated coronoid process and the body of the malar homolateral bone is known as Jacob's disease. Coronoid process hyperplasia was first described in 1853 by Von Langenbeck, and it was not until 1899 when Oscar Jacob described the disease that it was named after him. Jacobs's disease is an uncommon entity with only a few documented cases in the literature. The condition first manifests with progressive limitation of mouth opening and facial asymmetry. Pain is uncommon and it mainly affects young patients. Different factors have been postulated as possible causes, including temporal muscle hyperactivity, previous trauma, chronic disc dis…

Predicting the landslides triggered by the 2009 96E/Ida tropical storms in the Ilopango caldera area (El Salvador, CA): optimizing MARS-based model b…

2019

The main topic of this research was to evaluate the effect in the performance of stochastic landslide susceptibility models, produced by differences between the triggering events of the calibration and validation datasets. In the Caldera Ilopango area (El Salvador), MARS (multivariate adaptive regression splines)-based susceptibility modeling was applied using a set of physical–environmental predictors and two remotely recognized landslide inventories: one dated at 2003 (1503 landslides), which was the result of a normal rainfall season, and one which was produced by the combined effect of the Ida hurricane and the 96E tropical depression in 2009 (2237 landslides). Both the event inventorie…

Build up of patches caused by Rhizoctonia solani

2010

Rhizoctonia solani is a complex species that is composed of different anastomosis groups (AG). Although these different AGs show differences in their host ranges, generally R. solani is a phytopathogenic species with a wide spectrum of hosts. It has the ability to grow as a saprotroph, which further complicates its behaviour as a parasite. The losses caused by R. solani are very important and need a sustainable management strategy. The patchy appearance of the disease caused by this pathogen is well-known. The patches show within and between season dynamics. The factors which affect the spread of the disease can be grouped into three main categories: host plant, pathogen and environment. Ho…

PRELIMINARY-OBSERVATIONS OF METABOLIC CHARACTERIZATION OF BILATERAL TEMPORAL EPILEPTIC FOCUS, USING PROTON MAGNETIC-RESONANCE SPECTROSCOPY - 3 CASES

1994

International audience; Abstract: The authors report the case of 3 patients with bilateral temporal lobe epilepsy demonstrated by EEG and sphenoidal electrodes. Two out of the 3 patients presented with childhood febrile convulsions. Their neurological and mental examination was normal. EEG showed spikes within the anterior part of the 2 temporal lobes. CT scan and MRI showed no atrophic lesion within the 2 temporal lobes. Proton magnetic resonance spectroscopy, performed within a cube of 8 cube-centimetres localized in the anterior part of the 2 temporal lobes showed a significant decrease of N-acetyl-aspartate in the 2 temporal lobes of the 3 cases, compared with controls matched with age,…
