Clinical efficacy of semiconductor laser application as an adjunct to conventional scaling and root planing.
2005
Background and Objectives: The aim of the in vitro study was to examine the clinical efficacy of semiconductor laser periodontal pocket irradiation as an adjunct to conventional scaling and root planing. Materials and Methods: Twenty-two healthy patients with a need of periodontal treatment (15 women, 7 men, mean age 45.0� 10.8 years) with at least four teeth in all quadrants, were included. All of them underwent a conventional periodontal treatment including scaling and root planing. Using a split mouth design, two randomly chosen quadrants (one upper and the corresponding lower one) were subsequently treated with an 809 nm GaAlAs laser operated at a power output of 1.0 Watt using a 0.6 mm…
Infective endocarditis: review of 36 cases
2009
In a retrospective study of cases of infective endocarditis (IE) observed in adult patients, the data of patients hospitalized for definite IE in the Cardiosurgery Unit of ARNAS-Civico in Palermo (Italy) from March 2003 to September 2006 were analysed. All cases were classified according to the modified Duke criteria. In all, 36 immunocompetent patients with "definite" IE were included (20 males and 16 females with a median age of 54 years). The aortic valve (23/36, 64%) was the most commonly involved, followed by the mitral (19/36, 52.7%) and tricuspid valve (4/36, 11%). In 10 patients (27.7%), a double localization was observed. Blood culture yielded a positive result in 15 cases. Staphyl…
Predictors of weight loss after an intensive lifestyle intervention program in obese patients: a 1-year prospective cohort study.
2013
Published Version of an article in the journal: Health and Quality of Life Outcomes. Also available from the publisher at: http://dx.doi.org/10.1186/1477-7525-11-165 Open access Background Studies of lifestyle intervention programs in morbid obesity report large variations in weight loss outcomes. This is reported not only between but also within standardized programs. Such reports point to participants’ characteristics as possible predictors of this outcome. The aim of this prospective cohort study was to identify predictors of weight loss after a 1-year partly residential intensive lifestyle intervention program (ILI). Methods Morbidly obese patients (n=199), all Caucasian, 71% women, mea…
NK/T-cell lymphomas 'nasal type': an italian multicentric retrospective survey
2006
Abstrac Objective: To evaluate the clinical characteristics and outcome of NK/T-cell lymphoma ‘nasal type’ developed in Italian patients. Patients: Between 1997 and 2004, 26 new cases of NK/T-cell lymphoma ‘nasal type’ were diagnosed in 10 Italian Hematology institutions. Results: All patients were Caucasian, male/female ratio was 19/7, with a median age of 50 years (range 20–80). In 23 cases presentation at the onset was in the nasal cavity or adjacent structures, in two cases the lymphoma onset with skin lesions was followed successively by rhynopharyngeal dissemination, while the remaining case had bone marrow and lymph node involvement followed by oro-pharyngeal involvement. Regarding t…
A Phase II Study of Levofolinic Acid and 5-Fluorouracil Plus Cisplatin in Patients with Advanced Head and Neck Squamous Cell Carcinoma
1993
Forty patients with advanced squamous cell carcinoma of the head and neck (SCHNC) were treated with a combination of levofolinic acid 100 mg/m2+5-fluorouracil 375 mg/m2 in a 4-hour infusion plus cisplatin 20 mg/m2 in a 2-hour infusion for 5 consecutive days, repeated every 21-28 days. In the group of 20 previously untreated patients, a 90% overall response rate (ORR) with a 30% complete response rate (CRR) was obtained. In the group of 20 pretreated patients with recurrent and/or metastatic SCHNC, a 55% ORR with 15% CRR was achieved. This treatment was given on an outpatient basis and was generally very well tolerated with only 2 patients requiring hospitalization. Grade 1-2 gastrointestina…
Safety and efficacy of STI-571 (imatinib mesylate) in patients with bcr/abl-positive chronic myelogenous leukemia (CML) after autologous peripheral b…
2001
We examined safety and efficacy of STI-571 in 24 bcr/abl-positive patients with CML post PBSCT. At start of STI-571 therapy, nine patients presented in blast crisis (BC) or in accelerated phase (AP), and 15 in chronic phase (CP). Patients were evaluated for hematologic, cytogenetic and molecular response, survival and toxicity. In general, STI-571 was well tolerated in this heavily pretreated group of patients with a non-hematologic and hematologic toxicity profile similar to that observed in a previous phase I trial at comparable doses. Five of nine patients with CML in transformation (AP, BC) were evaluable for hematologic response. Two of five patients had transient reductions in WBC and…
Chemoradiotherapy of Newly Diagnosed Glioblastoma With Intensified Temozolomide
2009
Purpose To evaluate the toxicity and efficacy of chemoradiotherapy with temozolomide (TMZ) administered in an intensified 1-week on/1-week off schedule plus indomethacin in patients with newly diagnosed glioblastoma. Patients and Methods A total of 41 adult patients (median Karnofsky performance status, 90%; median age, 56 years) were treated with preirradiation TMZ at 150 mg/m 2 (1 week on/1 week off), involved-field radiotherapy combined with concomitant low-dose TMZ (50 mg/m 2 ), maintenance TMZ starting at 150 mg/m 2 using a 1-week on/1-week off schedule, plus maintenance indomethacin (25 mg twice daily). Results The median follow-up interval was 21.7 months. Grade 4 hematologic toxicit…
Preradiation chemotherapy of children and young adults with malignant brain tumors: Results of the german pilot trial HIT'88/'89
1998
Background Preradiation chemotherapy could be beneficial in malignant brain tumors, because the blood-brain tumor-barrier is disrupted after surgery, bone marrow recovery--essential for intense chemotherapy--is still intact, and CNS toxicity and ototoxicity of active drugs are lower before irradiation of a child's brain. Patients and methods A neoadjuvant phase 2 and a single arm pilot trial were initiated to investigate the efficacy and toxicity of an intense multidrug regimen before radiotherapy in 147 patients aged between 3 and 29; 9 years with medulloblastoma (94), malignant glioma (22), ependymoma (21), and stPNET (10). They were treated with one or two cycles consisting of procarbazi…
Overexpression of GLUT-1 is associated with resistance to radiotherapy and adverse prognosis in squamous cell carcinoma of the oral cavity
2006
This study tested the hypothesis that GLUT-1 is a marker of radioresistance in oral squamous cell carcinomas (OSCC). A GLUT-1 labeling index (LI) was determined by immunohistochemistry in 40 pretreatment OSCC biopsies. Radiation responses were categorized by histopathology of the resection specimens. Associations between the LI and radiation response, Kaplan-Meier survival estimates and Cox regression analysis for the variables GLUT-1, T-stage, N-stage and chemotherapy were examined. The median LI was 64.2% (range 14-100%). Tumors with65% of GLUT-1+cells were more resistant to radiation (p=0.023). Overall survival was higher (p=0.044) for subjects with low LI (median value) than those with …
Prognosis of patients with primary central nervous system lymphoma after high-dose chemotherapy followed by autologous stem cell transplantation
2013
High-dose chemotherapy followed by autologous stem cell transplantation has been shown to be feasible and highly effective in newly diagnosed primary central nervous system lymphoma. In this retrospective multicenter study, we investigated prognosis and baseline risk factors in patients with primary central nervous system lymphoma who underwent this treatment approach. We retrospectively analyzed 105 immunocompetent patients with primary central nervous system lymphoma who underwent high-dose chemotherapy followed by autologous stem cell transplantation with or without whole brain radiotherapy as first-line consolidation treated at 12 German centers between 1997 and 2011. We estimated survi…
