Prospective, cross-over, single-center trial comparing oral double-balloon enteroscopy and oral spiral enteroscopy in patients with suspected small-b…

2011

BACKGROUND AND STUDY AIMS: Spiral enteroscopy is a new, promising rapid enteroscopy technique. A prospective cross-over study was carried out to compare this new method with the established technique of double-balloon enteroscopy (DBE). PATIENTS AND METHODS: From an initial group of 18 patients with suspected mid-gastrointestinal bleeding due to vascular malformations but no previous history of small-bowel or colonic surgery, 10 patients (mean age 69 years) completed the study. Patients underwent both enteroscopy techniques with an oral approach, in a randomized sequence. The deepest point reached during advancement in the first enteroscopy was marked with India ink. The primary end point o…

In vivo evaluation of periodontal microcirculatory changes associated with endodontic treatment.

2014

The purpose of this study was to investigate in vivo the gingival microcirculatory changes associated with endodontic treatment using the continuous wave of condensation technique. MATERIALS AND METHODS: Twenty necrotic one canal roots of 20 cooperative patients of both sexes, aged between 20 and 43 years, were selected. All patients were examined by capillaroscopy before, immediately after endodontic treatment, and after 7 days. The last examination was carried out by the same operator, and repeated twice for each examined area: masticatory, buccal and labial mucosa corresponding to the endodontically treated root. All canals were prepared using a simultaneous technique with Ni-Ti files (M…

The supraorbital endoscopic approach for aneurysms.

2013

Objective To review our surgical experience in minimally invasive transcranial endoscope-assisted microsurgical treatment of intracranial aneurysms, using the supraorbital keyhole craniotomy. Methods The supraorbital keyhole approach was performed through an eyebrow skin incision in 793 cases for treatment of 989 intracranial aneurysms. Of patients, 474 were operated on after subarachnoid hemorrhage, and 319 were operated on under elective conditions. After lateral frontobasal burr hole trephination, a limited subfrontal craniotomy was created. To achieve adequate intraoperative exposure through the limited approach, endoscopes were used routinely. Surgical outcome was assessed using the mo…

Laparoscopic adrenalectomy: preoperative data, surgical technique and clinical outcomes

2019

Background: laparoscopic adrenalectomy has become the standard treatment for adrenal lesions. The better clinical outcoms of laparoscopic technique are valid for treatment of small benign masses (< 5-6 cm), instead there are still open questions in literature regarding the correct management of larger lesions (> 6 cm) or in case of potentially malignant adrenal tumors. The aim of this study is to evaluate the outcomes of laparoscopic adrenalectomy in a referral surgical department for endocrine surgery. Methods: at the University Hospital Policlinico "P. Giaccone" of Palermo between January 2010 and December 2017 we performed a total of 81 laparoscopic adrenalectomy. We created a retr…

Rupture of supra-aortic neck arteries due to lesions caused by tracheal tubes

1984

Haemorrhages from the common carotid or innominate artery caused by tracheal tubes are rare but dramatic complications of head and neck surgery. Patients with metal tracheostomy cannulas or patients in the phase of wound healing after radical tumour resections of the pharynx and larynx run a greater risk. Following extensive tumour resections and radiation of the upper respiratory and digestive tracts in 680 patients, acute bleeding of the larger neck arteries occurred in 18 patients. In four of these cases, fistulae developed in the innominate or common carotid artery. These ruptures were caused by both plastic and metal tracheal tubes.

Measurement of end-tidal carbon dioxide in spontaneously breathing patients in the pre-hospital setting. A prospective evaluation of 350 patients

2002

Monitoring of end-tidal carbon dioxide (EtCO(2)) is good clinical practice in the patient who is intubated and ventilated. This study investigated the EtCO(2) values in spontaneously breathing patients treated in a physician-staffed mobile intensive care unit (MICU). This article also discusses whether EtCO(2) monitoring may have an influence on therapeutic decisions by emergency physicians by providing additional information.Over a period of 6 months, 350 spontaneously breathing patients (162 males, 137 females) were treated and transported in our MICU and monitored using a LifePak 12 monitor (EtCO(2), respiratory rate, pO(2), blood pressure, heart rate). Only 299 were enrolled in the stud…

The effect of cigar smoking on the lingual microcirculation

2005

The aim of this study was to analyze the lingual microcirculation in vivo and to evaluate the effects on it of cigar smoking, using computerized videocapillaroscopy. Twenty-five healthy nonsmokers and 25 healthy smokers were examined. For each subject we evaluated the visibility, course, tortuosity, and any images characteristic of capillary loops, as well as the possible presence of microhemorrhages, the average caliber of the capillary loops, and the number of capillary loops visible per square millimeter. The investigation of the lingual mucosa revealed capillary loops with a course parallel to the surface. In smokers, capillary loops had a smaller caliber (P < 0.001) and there was a hig…

Efficacy and safety during formulation switch of a pasteurized VWF/FVIII concentrate: results from an Italian prospective observational study in pati…

2012

Summary Von Willebrand disease (VWD) is an inherited bleeding disorder caused by the quantitative or qualitative deficiency of von Willebrand factor (VWF). Replacement therapy with plasma-derived VWF/factor VIII (FVIII) concentrates is required in patients unresponsive to desmopressin. To assess the efficacy, safety and ease of use of a new, volume-reduced (VR) formulation of VWF/FVIII concentrate Haemate® P in patients requiring treatment for bleeding or prophylaxis for recurrent bleeding or for invasive procedures. Pharmacoeconomic variables were also recorded. Data were analysed using descriptive statistics. This was a multicentre, prospective, observational study. Consecutively enrolled…

Secondary prophylaxis vs. on-demand treatment to improve quality of life in severe adult haemophilia A patients: a prospective study in a single cent…

2013

Background Retrospective publications show a decrease in the bleeding frequency and an improvement in the quality of life (QoL) in severe adult haemophilia A (SAHA) after switching from the on-demand treatment (DT) to secondary prophylaxis (SP). But there are no prospective studies which demonstrate, using a haemophilia-specific questionnaire, an improvement in the QoL after such treatment change. The main objective of this study is to prospectively compare the QoL and the musculoskeletal assessment after switching from DT to SP in SAHA using the A36 Hemofilia-QoL®. As secondary objective, we compare the haemarthrosis frequency and factor VIII consumption in DT and SP during a similar perio…
