Proliferative Activity and Cytometric Characteristics in Polyps of the Nasal Cavity and Paranasal Sinuses
2000
Although several investigations have revealed the influence of cytokines, allergy, and environmental factors in polyp development, the etiology of nasal polyps is still unknown. To estimate the biology of this common disease the operative specimens of 50 patients who underwent surgery for polyps of the nasal cavity and the paranasal sinuses were examined; of these, 10 patients had recurrent disease and 23 patients had an allergy. The investigations included routine histology and quantitative DNA measurements, along with immunohistochemical identification of proliferation markers (i.e., MIB-1; proliferating cell nuclear antigen, PCNA). Histologically, most polyps revealed an infiltration wi…
Endonasal Approach for Nasal and Paranasal Sinus Tumor Removal
2001
Patients with benign (53) and malignant (22) tumors of the nose and paranasal sinuses were treated for tumor removal via an endonasal approach. Patient selection was based on tumor location (centrally) rather than histology. Tumors attainable by the endonasal approach were located in the nasal cavity, the ethmoid sinus, the sphenoid sinus and the medial wall of the maxillary sinus. Endonasal microscopic techniques including endonasal orbital decompression and endonasal closure of CSF-leaks were combined with surgical navigation tools in selected cases. Surgical trauma and morbidity could be minimized without compromising radicality of tumor removal. Postoperative hospitalization was compara…
The Use of Acoustic Rhinometry in Predicting Outcomes after Sinonasal Surgery
2000
Today's healthcare environment demands objective assessment of surgical outcomes. The recent otolaryngologic literature has established acoustic rhinometry (AR) as a valid instrument to objectively document nasal patency. The purpose of this article is to evaluate the utility of AR in predicting outcomes after sinonasal surgery. All patients scheduled for sinonasal surgery at the Tulane University and University of Mainz Departments of Otolaryngology between 10/1/98 and 12/15/98 were enrolled. All subjects underwent AR and completed a sinonasal outcome survey (SNOT-20) one day before and two months after their surgical procedure. Thirty-one patients were enrolled. The SNOT-20 raw scores im…
Association of kidney disease measures with risk of renal function worsening in patients with type 1 diabetes
2018
Background Albuminuria has been classically considered a marker of kidney damage progression in diabetic patients and it is routinely assessed to monitor kidney function. However, the role of a mild GFR reduction on the development of stage ≥3 CKD has been less explored in type 1 diabetes mellitus (T1DM) patients. Aim of the present study was to evaluate the prognostic role of kidney disease measures, namely albuminuria and reduced GFR, on the development of stage ≥3 CKD in a large cohort of patients affected by T1DM. Methods A total of 4284 patients affected by T1DM followed-up at 76 diabetes centers participating to the Italian Association of Clinical Diabetologists (Associazione Medici D…
Lateralized and Bilateral Olfactory Function in Patients With Chronic Sinusitis Compared With Healthy Control Subjects
1998
Results of this study demonstrated that a new olfactory test, the "Sniffin' Sticks," can be used to distinguish hyposmic patients with chronic sinusitis (n = 63) from control subjects. Dirhinic testing yielded improved olfactory sensitivity compared with monorhinic testing. However, dirhinic results were not significantly different from results obtained for the best nostril.
FOLFIRINOX Bevacizumab Is a Promising Therapy for Chemorefractory Metastatic Colorectal Cancer
2014
<b><i>Purpose:</i></b> Fluoropyrimidines, oxaliplatin, irinotecan and targeted therapies represent the standard treatment of metastatic colorectal cancer. After failure of all these treatments, few options are available. In such chemorefractory patients the effect of triplet chemotherapy with bevacizumab (FOLFIRINOX bevacizumab) has never been investigated. <b><i>Patients and Methods:</i></b> 49 consecutive patients bearing unresectable metastatic colorectal cancer and who experienced failure to oxaliplatin- and irinotecan-based chemotherapy were treated with oxaliplatin (85 mg/m<sup>2</sup>), irinotecan (180 mg/m<sup>2</s…
RAS mutations and cetuximab in locally advanced rectal cancer: Results of the EXPERT-C trial
2013
Background: RAS mutations predict resistance to anti-epidermal growthfactor receptor (EGFR) monoclonal antibodies in metastatic colorectal cancer. We analysed RAS mutations in 30 non-metastatic rectal cancer patients treated with or without cetuximab within the 31 EXPERT-C trial. Methods: Ninety of 149 patients with tumours available for analysis were KRAS/BRAF wild-type, and randomly assigned to capecitabine plus oxaliplatin (CAPOX) followed by chemoradiotherapy, surgery and adjuvant CAPOX or the same regimen plus cetuximab (CAPOX-C). Of these, four had a mutation of NRAS exon 3, and 84 were retrospectively analysed for additional KRAS (exon 4) and NRAS (exons 2/4) mutations by using bi-di…
A Passive-Marker-Based Optical System for Computer-Aided Surgery in Otorhinolaryngology: Development and First Clinical Experiences
1999
Objectives: To develop a new type of optical computer-aided surgery (CAS) device that overcomes some of the restrictions of common systems and to examine its accuracy and usability under laboratory and intraoperative conditions. Study Design: Prospective study using laboratory experiments and intraoperative data collection. Methods: An optical CAS system applying passive optical markers for coordinate determination was developed. Laboratory accuracy measurements were obtained on a Plexiglas model with known coordinates of fiducial markers, before and after predefined table movements. Intraoperative accuracy measurements were recorded from 24 patients undergoing endonasal surgery of the para…
Differential effect of Incobotulinumtoxin A on pain, neurogenic flare and hyperalgesia in human surrogate models of neurogenic pain
2017
Background: The effectiveness of Botulinum-neurotoxin A (BoNT/A) to treat pain in human pain models is very divergent. This study was conducted to clarify if the pain models or the route of BoNT/A application might be responsible for these divergent findings. Methods: Sixteen healthy subjects (8 males, mean age 27 ± 5 years) were included in a first set of experiments consisting of three visits: (1) Visit: Quantitative sensory testing (QST) was performed before and after intradermal capsaicin injection (CAPS, 15 μg) on one thigh and electrical current stimulation (ES, 1 Hz) on the contralateral thigh. During stimulation pain and the neurogenic flare response (laser-Doppler imaging) were ass…
[Effectiveness of contemporary injection of botulinum toxin and topical application of glyceryl trinitrate against postoperative pain after Milligan-…
2007
PURPOSE: After haemorrhoidectomy the maximum resting pressure (MRP) of the anal canal is significantly increased. This increase play an important role in the making of postoperative pain. Recently, both the topical application of glyceryl trinitrate (GT) and the intrasphincter injection of botulinum toxin (Tox), resulted effective, in reducing temporary the MRP although with different mechanism of action. In this study the effectiveness and safe of contemporary injection of Tox and topical application of 300 mg/die of GT after Milligan-Morgan haemorrhoidectomy, were evaluated. MATERIALS AND METHODS: Ten patients, undergoing Milligan-Morgan haemorrhoidectomy for 3rd and 4th degree haemorrhoi…
