The forests in these regions have been seriously damaged. This contribution illustrates the methodology adopted in the emergency phase to estimate forest damages caused by Vaia storm, both in terms of damaged forest areas and growing stock volume of fallen trees. 494 Municipalities registered forest damages caused by Vaia, destroyed or intensely damaged forest stands amounted to about 42

BackgroundThe styloid process is a projecton of the temporal bone, its lenght is between 20 to 30 mm, when it is longer than 30 mm it is defined elongated styloid process. The aim of this study is an epidemiological evaluation of 1003 digital panoramic radiographs in an Italian population between 5 and 90 years old.Material and MethodsThis is a retrospective analysis and the radiographs were selected from the Complex Operating Unit of Dentistry of Padua University Hospital database. The radiographs were performed using a Sirona Ortophos XG and the styloid process length was measured using the measuring tool of Sidexis Software. It was measured from the point where it left the temporal bone plate to its tip. Styloid processes measuring more than 30 mm were considered elongated. Chi-squared test, Fligner-Killeen test, Shapiro-Wilk test and t-test with Welch correction were performed.ResultsIn the study 33.40% of the patients showed an elongated styloid process.ConclusionsThe number of patients with elongated styloid process and the mean length of the process increase with the age confirming the chronic development of the calcification described in literature. No statistically significant correlation is found between the presence of elongated styloid process and the gender and affected side (bilateral or unilateral).

A 12-year-old boy shows a restless sleep and snoring episodes declaring himself tired during the day and the school lessons. On clinical examination the patient presents a second-class profile, a retrusive jaw with a small chin and an open nasolabial angle. From the intraoral examination a tonsillar hypertrophy is denoted. The patient is sent by the ear, nose, and throat specialist (ENT) and subsequently subjected to a polysomnography (PSG). The ENT decides to subject him to a tonsillectomy and the subsequent PSG shows an improvement in the obstructive sleep apnea syndrome (OSAS) pathology with an apnea-hypopnea index (AHI) improved from 25.5 episodes/hr to 3.4 episodes/hr. Subsequently a orthodontic treatment with twin-block was start to further reduce the apnea episodes. The last PSG highlights the success of the treatment further lowering the AHI to 0.7 episodes/hr. This case report shows how a multidisciplinary approach to OSAS is fundamental also in the young patient and that the orthodontist carried out in this area a fundamental task both in diagnosis and treatment.

An eight-years-old girl showed a restless sleep with snoring and severe apnea episodes, a mandibular retrognathia, mouth breathing, maxillary transverse discrepancy, mandibular transverse discrepancy, moderate crowding and anterior open-bite. The CBCT showed an anterior collapse of the epiglottis. The treatment consisted in a rapid palatal expansion, an epiglottoplasty and a reduction of the tongue base. Polysomnography revealed that apnea-hypopnea index improved from 21,8 episodes/hr at the baseline to 0,6 episodes/hr, average oxygen saturation from 96,5% to 98,1%, oxygen desaturation events from 23,4 episodes/hr to 1/hr.

BackgroundThe aim of this study is to evaluate the prevalence of elongated styloid process in digital panoramic radiographs in a North Italian population in relation to age, gender and side.Material and MethodsThis study was performed as a retrospective analysis on digital panoramic radiographs of 600 (271 males and 329 females) Italian patients between 6 and 87 years old. The styloid process length were measured using the measuring tool of Sidexis Software. It was measured from the point where it left the temporal bone plate to its tip. Styloid processes measuring more than 30 mm were considered elongated. Chi-squared and Fisher tests were used and the test is considered significant if the p-value is lower or equal to 0.05.ResultsThirty-three per cent of the patients showed an elongated styloid process. Seventeen per cent were elongated on both right and left side, fifteen point nine per cent were elongated only in one side.ConclusionsThe prevalence of elongated styloid process was high and a progressive increase of the elongation prevalence was found in older groups.
