A web search methodology for different user typologies
2009
Search engines and directories are the main tools used to find desired information into the ocean of digital contents that is the Web. However, they are not presently able to understand the user specific needs and starting knowledge because their inability to simulate the processes of human mind. Natural Language Processing, Folksonomy, Semantic Web and Serendipitous Surfing are some of the recent research fields towards understanding of human natural language and in general of real user needs. This work aims to add one step more to this evolution path by presenting a new search methodology that allows users to create new knowledge paths on the web based on their specific requirements. Thus…
Improving Oral–Systemic Healthcare through the Interoperability of Electronic Medical and Dental Records: An Exploratory Study
2019
Objectives Electronic health records (EHRs) are rarely shared among medical and dental providers. The purpose of this study was to assess current information sharing and the value of improved electronic information sharing among physicians and dentists in Germany and the United States. Materials and Methods A survey was validated and distributed electronically to physicians and dentists at four academic medical centers. Respondents were asked anonymously about EHR use and the medical and dental information most valuable to their practice. Results There were 118 responses, a response rate of 23.2%. The majority (63.9%) of respondents were dentists and the remainder were physicians. Most res…
A nonlinear biomechanical model for evaluation of cerebrospinal fluid shunt systems.
1994
In view of complications arising from physical properties of cerebrospinal fluid shunts, a biomechanical model of hydrocephalus was set up to study in vivo parameters that may influence their function. These include: intracranial pressure, compliance and pulses, intrathoracic, intra-abdominal, and subcutaneous pressures, and the effects of siphonage and repeated valve flushing. Each of these factors was studied separately upon shunt implantation in the model. Results of testing of a sample low-pressure valve with antisiphon device conformed with consumer information in regard to valve opening pressure and pressure flow measurements. No customer information, however, was supplied concerning …
Impact of CT and MR on the Diagnostic Evaluation of Neurologic and Neurosurgical Diseases
1989
Today CT and MR are considered to be the most important and most reliable methods for the diagnosis of brain tumors. The sensitivity of these modalities in the detection of intracranial tumors approaches 100%. The extraordinary value of both methods is based not only on this high detection rate but also on their ability to localize tumors in relation to vital centers, assess their mass effect, and establish the tissue type of the lesion (= specificity).
The association of patient age with postoperative morbidity and mortality following resection of intracranial tumors
2021
Abstract Introduction The postoperative functional status of patients with intracranial tumors is influenced by patient-specific factors, including age. Research question This study aimed to elucidate the association between age and postoperative morbidity or mortality following the resection of brain tumors. Material and methods A multicenter database was retrospectively reviewed. Functional status was assessed before and 3–6 months after tumor resection by the Karnofsky Performance Scale (KPS). Uni- and multivariable linear regression were used to estimate the association of age with postoperative change in KPS. Logistic regression models for a ≥10-point decline in KPS or mortality were b…

Efficacia di Buprenorfina/Naloxone nel trattamento delle tossicodipendenze: monitoraggio dei pazienti in terapia presso il Ser.T. di Marsala, ASL n. …
2018
Il lavoro sperimentale è stato eseguito nel periodo gennaio 2016-marzo 2017, presso il Ser.T. di Marsala dell’ASL n. 9 di Trapani, sotto la guida del Dott. Gaetano Gurgone e del Prof. Fabio Venturella, lavoro in cui sono stati altresì analizzati i dati relativi agli ultimi cinque anni. Il compito prevalente del Ser.T. è l’assessment, inteso come processo di raccolta, integrazione ed interpretazione delle informazioni.Si esplica attraverso: la diagnosi, la cura, la riabilitazione. Questo lavoro vuole essere quindi il resoconto di 15 mesi di osservazione su pazienti trattati con Buprenorfina/Naloxone,operando un confronto con pazienti trattati con il Metadone.Il campione è costituito da 32 so…
Endoscope-assisted microsurgery for cerebral aneurysms.
1999
A total of 66 patients with intracranial aneurysms were endoscopically assisted treated during a 3 years period. Among those were five individuals with giant aneurysms and 27 patients with aneurysms of the posterior circulation. The endoscope was used only for checking the anatomical structures surround the aneurysms in 16 cases. In 43 patients the aneurysm sac was also dissected under endoscopical con-trol. Even the clipping procedure was performed in seven cases exclusively under endoscopical obser-vation. Only one prematural rupture occurred intraoperatively during preparation of a basilar tip aneurysm. Postoperatively three individuals with aneurysms located in the posterior circulation…
Head and Neck Paragangliomas
2016
Head and neck paragangliomas are highly vascularized neuroendocrine tumors derived from the extra-adrenal paraganglia of the autonomic nervous system. These tumors may occur either sporadically or in the context of a hereditary familial tumor syndrome, and multifocal presentations are observed, particularly in hereditary cases. Hereditary paragangliomas are mostly caused by mutations in the succinate dehydrogenase complex genes. Early imaging, with ultrasonography of the neck and magnetic resonance imaging (MRI) of the skull base, is essential for localizing and assessing the extent of the tumor, as well as for precise planning of the treatment approach. Views regarding the treatment of cho…
