Factors influencing transfer accuracy of cone beam CT-derived template-based implant placement.
2011
Objectives The aim of the present investigation was the analysis of the factors presumptively affecting the accuracy outcome of cone-beam computed tomography (CBCT)-derived laboratory-based surgical guides for implant placement in partially edentulous patients. Materials and methods In 52 partially edentulous patients a total of 132 implants were placed following CBCT diagnostics with the aid of laboratory-fabricated, tooth-borne templates. Based on the image fusion technique measurements were done to calculate linear and angular deviations between virtually planned and placed implants. The implant sites were stratified according to four factors that presumably may influence the transfer ac…
Myocardial infarction following convulsive and nonconvulsive seizures
2009
Abstract Myocardial infarction (MI) has been rarely reported in association with seizures, and only of convulsive type. Methods We describe a series of five patients observed over a 4-year period, who presented MI immediately following seizures, either convulsive or nonconvulsive. Results Patient 1 had pre-existent coronary disease (CD) and presented multiple focal nonconvulsive seizures. Patient 2 had no CD, normal coronary angiography and presented secondary generalized convulsive seizures. Patient 3 had no history of CD, normal angiography and had a first single convulsive seizure. Patient 4 had severe CD and suffered from a single convulsive event. Patient 5 had a partial and a generali…
Modified fronto-lateral laryngectomy in treatment of glottic T1(a-b) cancer with anterior commissure involvement
2010
Abstract Objective Evaluation of clinical and oncological safety of the modified fronto-lateral laryngectomy in the treatment of T1a-b glottic cancer. Methods Retrospective review of charts of patients managed with classical fronto-lateral laryngectomy or with our modified technique using a cervical fascia flap and a false cord flap to reconstruct the defect. Results No recurrence of cancer was observed in the present series and slight dysphonia was present in all cases. The patients managed with classical technique required a revision surgery for granulations or anterior synechia in 4 cases; those managed with modified technique did not need a second intervention. Conclusion The fronto-lat…
Management of shortened dental arches and periodontal health: 5-year results of a randomised trial
2014
Summary In a multicentre randomised trial (German Research Association, grants DFG WA 831/2-1 to 2-6, WO 677/2-1.1 to 2-2.1.; controlled-trials.com ISRCTN97265367), patients with complete molar loss in one jaw received either a partial removable dental prosthesis (PRDP) with precision attachments or treatment according to the SDA concept aiming at pre-molar occlusion. The objective of this current analysis was to evaluate the influence of different treatments on periodontal health. Linear mixed regression models were fitted to quantify the differences between the treatment groups. The assessment at 5 years encompassed 59 patients (PRDP group) and 46 patients (SDA group). For the distal meas…
Predicting positive surgical margins in partial nephrectomy: A prospective multicentre observational study (the RECORd 2 project)
2020
PURPOSE: to evaluate clinical predictors of positive surgical margins (PSMs) in a large multicenter prospective observational study and to develop a clinic nomogram to predict the likelihood of PSMs after partial nephrectomy (PN). MATERIALS AND METHODS: We prospectively evaluated 4308 patients who had surgical treatment for renal tumors between January 2013 and December 2016 at 26 urological Italian Centers (RECORd 2 project). Two multivariable logistic models were evaluated to predict the likelihood of PSMs. Center caseload was dichotomized using a visual assessment adjusted for several predictors of PSMs. A nomogram predicting PSMs was developed. RESULTS: Overall, 2076 patients treated wi…
Modulatory effects of nitric oxide-active drugs on the anticonvulsant activity of lamotrigine in an experimental model of partial complex epilepsy in…
2007
Abstract Background The effects induced by administering the anticonvulsant lamotrigine, the preferential inhibitor of neuronal nitric oxide synthase 7-nitroindazole and the precursor of NO synthesis L-arginine, alone or in combination, on an experimental model of partial complex seizures (maximal dentate gyrus activation) were studied in urethane anaesthetized rats. The epileptic activity of the dentate gyrus was obtained through the repetitive stimulation of the angular bundle and maximal dentate gyrus activation latency, duration and post-stimulus afterdischarge duration were evaluated. Results Either Lamotrigine (10 mg kg-1) or 7-nitroindazole (75 mg kg-1) i.p. administration had an ant…
Increased cortical curvature reflects white matter atrophy in individual patients with early multiple sclerosis
2014
Objective White matter atrophy occurs independently of lesions in multiple sclerosis. In contrast to lesion detection, the quantitative assessment of white matter atrophy in individual patients has been regarded as a major challenge. We therefore tested the hypothesis that white matter atrophy (WMA) is present at the very beginning of multiple sclerosis (MS) and in virtually each individual patient. To find a new sensitive and robust marker for WMA we investigated the relationship between cortical surface area, white matter volume (WMV), and whole-brain-surface-averaged rectified cortical extrinsic curvature. Based on geometrical considerations we hypothesized that cortical curvature increa…
The safety and efficacy of add-on levetiracetam in elderly patients with focal epilepsy: A one-year observational study
2011
Abstract Purpose The long-term safety and efficacy of levetiracetam (LEV) was evaluated as add-on therapy in focal epilepsy patients ( n =491) aged at least 65 years who failed at least one monotherapy. Methods Patients ( n =491) with focal epilepsy treated with at least one antiepileptic drug in monotherapy with insufficient seizure control were included in this prospective open-label study. The recommended LEV dose range was 1000–3000mgperday. Follow-up visits were done approximately after 3, 6 and 12 months. Safety and efficacy was analysed based on all patients who received LEV (safety population, n =491) and all patients who were seen at all visits and completed the trial (per protocol…
Social cognition and executive functions in children and adolescents with focal epilepsy
2020
Objectives: Deficits in facial emotion recognition and Theory of Mind are frequent in patients with epilepsy. Although this evidence, studies on pediatric age are few and the relation between these abilities and other cognitive domain remains to be better elucidated. The purpose of our study is to evaluate facial emotion recognition and Theory of Mind in children and adolescents with focal epilepsy, and correlate them with intelligence and executive functions. Materials and methods: Our work is a cross-sectional observational study. Sixty-two children and adolescents aged between 7-16 years diagnosed by focal epilepsy and 32 sex/age-matched controls were recruited. All participants were adm…
Rhinitis as a risk factor for depressive mood in pre-adolescents: a new approach to this relationship
2014
Background Respiratory allergic symptoms impact on social life and school activities, influencing the patient's mood states. We evaluated the relationships between allergic respiratory diseases and depressive/anxious mood in a large sample of Italian middle school students, using the partial directed acyclic graph (P-DAG). Methods We studied 1283 subjects aged 10–13. A health respiratory questionnaire including questions relevant to socioeconomic status (HCI) and a test for depression and anxiety were administered. All subjects performed spirometry and skin prick tests. Results A causal role of rhinitis on depression was found: the likelihood of being depressed increased from 11.2 to 17.7%,…
