[Limits of quantitative coronary angiography (QCA) in intermediate stenosis measuring: a correlation and concordance study with intravascular ultrasound (IVUS)].

Background: Although coronarography is still the gold standard to evaluate coronary lesions, it remains a bidimensional representation of a tridimensional complex structure, which can represent a source of error in measurements.

Aims: to perform a correlation and concordance study between quantitative coronary angiography (QCA) and intravascular ultrasound measurements for intermediate and ambiguous lesions.

Methods: We analysed 40 patients' coronary arteries from March 2009 to November 2011 by both QCA and intravascular ultrasound to perform then a correlation and concordance study.

[Role of intravascular ultrasound (IVUS) in determining the therapeutic strategy for the patients with intermediate coronary lesions].

Background: Coronarography presents some limits in assessing intermediate stenosis. Intravascular ultrasound provides tridimensional measurements of the artery, with more reliable data guiding revascularization decision.

Aims: to evaluate the impact of intravascular ultrasound measurements on revascularization decision of intermediate and ambiguous coronary lesions.

Metastasizing pleomorphic adenoma of the submandibular gland: a case report.

Pleomorphic adenoma (PA), originally called mixed tumour, is the most common neoplasm of the salivary glands. It is usually a benign, slow-growing and well-circumscribed tumour. However, PA may occasionally give rise to metastases that usually occur after a previous recurrence.

Comparison of coronary calcifications detection by angiogram versus intravascular ultrasound.

Background: The presence, extent and location of calcium in coronary artery lesions are important determinants of the success of per cutaneous coronary intervention (PCI). Although coronarography remains the gold standard for coronary disease detection, Intravascular ultrasound ( IVUS) is proposed as a superior technique for identifying patients with coronary artery calcification .

Aim: To define sensibility and specificity of coronary angiography in detecting calcifications considering the IVUS as gold standard.

[Coronary artery bypass grafting in diabetic patients: early and mid-term outcomes].

Background: The outcome of coronary artery bypass grafting (CABG) in diabetic patients has traditionally been worse than in nondiabetic patients. Recent studies have suggested an improvement in outcome in diabetic patients undergoing CABG. However, the direct impact of diabetes on mortality and morbidities following CABG remains unclear.

[Single versus bilateral internal thoracic artery grafts for multi vessel coronary artery bypass grafting: mid-term results].

Background: The issue of superiority of single internal thoracic artery grafting versus bilateral internal thoracic artery grafting remains unresolved.

Aim: The aim of this study was to compare the early results and midterm outcome of single and bilateral internal thoracic artery grafting for multivessel coronary artery bypass grafting.

Methods: Between January 2005 and March 2010, 196 patients underwent primary coronary artery bypass grafting with at least one internal thoracic artery grafts.

[Myocardial infarction after conduction electrical weapon shock].

Controversy persists over the safety of conducted electrical weapons, which are increasingly used by law enforcement agencies around the world. We report a case of 33-year-old man who had an acute inferior myocardial infarction after he was shot in the chest with an electrical weapon.

Myoepithelioma of the vallecula: a case report.

Myoepitheliomas are rare and generally benign neoplasms that account for fewer than 1% of all salivary gland tumors. A myoepithelioma neoplasm is almost entirely composed of myoepithelial cells and is most frequently located in the parotid gland and in the minor salivary glands of the hard palate. We report an extremely rare case of myoepithelioma of the vallecular region in a 65-year-old woman and describe this tumor's clinical peculiarity, diagnostic and therapeutic considerations, and prognosis.

Sintering behavior of magnesium-substituted fluorapatite powders prepared by hydrothermal method.

Magnesium-substituted fluorapatite powders were synthesized by hydrothermal method, and their sintering behavior was investigated by dilatometry in the temperature range 25-1100°C. Analysis of the obtained powders by X-ray diffraction and (31)P NMR spectroscopy showed that the powders consisted of a single apatite phase and no amorphous phase has been formed. Compared to pure fluorapatite, the shrinkage of the substituted samples occurred in two steps and the temperature at which the sintering rate was maximum is lower.

[Cervico-facial hydatidosis. Report of 17 cases].

Background: Cervico-facial hydatid cyst is rare. It accounts for 1 % of echinococcosis locations.

Aim: To describe the epidemiological, clinical and therapeutic aspects of cervico-facial hydatid cysts based on our clinical experience and data in the literature.

[Surgical treatment of secondary hyperparathyroidism in patients with chronic renal failure].

Objective: To identify the indications for subtotal parathyroidectomy (PTX) in secondary hyperparathyroidism (SHPT) and report postoperative, early and late complications of PTX.

Patients And Methods: We conducted a retrospective study of subjects with chronic renal failure operated in Tunisian hospitals who received subtotal PTX over 10 years from January 1997 to December 2007. We analyzed the clinical, biological and radiological parameters pre- and postoperatively.

Therapeutic approaches to complicated cholesteatoma of the external auditory canal: a case of associated facial paresis.

Spontaneous cholesteatoma of the external auditory canal (EAC) is an uncommon condition that is difficult to diagnose. In a patient with such a possibility, serious clinical investigation along with radiologic and histologic exploration should be performed early on because a delay in treatment can lead to severe complications. Given the rarity of EAC cholesteatoma, no therapeutic consensus has emerged.

Rosai-Dorfman disease of the nasal cavities: A CO(2) laser excision.

Background: Rosai-Dorfman disease (RDD) is a rare nonneoplastic histiocytic proliferative disorder characterized by painless massive lymphadenopathy. Extranodal manifestations frequently occur in the head and neck area.

Methods: We report the clinical and histological features of nasal cavities and cervical lymph node RDD in a 72-year-old woman, who complained of major nasal obstruction and hyposmia.

[Bronchoscopic findings in children with prolonged respiratory symptoms].

Objective: This retrospective study aims to establish an algorithm indicating a bronchoscopy, based on clinical and radiological criteria predictive of the presence of a foreign body (FB), in children with prolonged respiratory symptoms and no history of foreign body aspiration (FBA); to establish a study of these criteria and to compare the clinical, radiological and broncoscopic findings in such cases.

Methods: We chose to review the records of 73 children (age < or = 15 years) with prolonged respiratory symptoms (for at least 15 days) and no history of FBA who underwent bronchoscopy at our institution between 1996 and 2005.

Results: The mean age was 3 years and 2 months, the majority of the patients were between 1 and 3 years of age (56%), 59% of the patients were boys and the mean of evolution of symptoms before the broncoscopy was 3 months and 3 weeks.
