As risk-modifiers of alcohol and tobacco effects, metabolic genes polymorphisms were investigated as susceptibility candidates for squamous cell carcinoma of the head and neck (SCCHN). A total of 210 cases and 245 hospital controls, age and gender matched, were genotyped for CYP1A1, CYP2E1, GSTM1, GSTT1, EPHX1 exons 3 and 4, and NAT2 polymorphisms. A(More)
The purpose of this study is to analyze the combined effects of selected p53 and p73 polymorphisms and their interaction with lifestyle habits on squamous cell carcinoma of the head and neck (SCCHN) risk and progression in an Italian population. Two hundred and eighty-three cases and 295 hospital controls were genotyped for p53 polymorphisms on exon 4(More)
Cervicofacial actinomycosis, a rare chronic infectious disease, is, however, an important clinical entity, due to the difficulties involved, still today, in its diagnosis. Following personal experience in a case referred to our Department, and in agreement with reports in the literature, attention is drawn to the presenting clinical manifestations,(More)
Arachnoid cysts account for almost 1% of neoformations located in the cerebellopontine angle. The aetiopathogenesis is unknown. Arachnoid cysts of the cranial posterior fossa may produce symptoms typical of a tumour such as headache, dizziness, tinnitus and progressive sensorineural hearing loss. Management of these lesions is still controversial; if the(More)
Purpose: Sulfotransferases (SULT) 1A1 detoxifie and bioactivate a broad spectrum of substrates including xenobiotics. The SULT1A1 gene possesses a G→A polymorphism that results in an Arg to His substitution at codon 213, with the His allele having a low activity. The purpose of this study was to evaluate whether SULT1A1 Arg213His polymorphisms are risk(More)
Abstract Aims/hypothesis. Serum anti-CD38 autoantibodies (aAbs) have been reported in 17 to 19% of patients with long-standing Type I (insulin-dependent) diabetes mellitus and Type II (non-insulin-dependent) diabetes mellitus. Whether these aAbs are also found in new-onset Type I diabetes and in Latent Autoimmune Diabetes in Adults (LADA) is not known, as(More)
OBJECTIVE To evaluate the role of oropharyngoesophageal scintigraphy in the diagnostic approach to patients with laryngopharyngeal reflux (LPR). STUDY DESIGN Forty-one patients with chronic laryngopharyngeal symptoms and a control group of 15 healthy volunteers were examined. All subjects underwent standard oropharyngoesophageal scintigraphy. The(More)
A correlation between laryngo-pharyngeal reflux and laryngeal carcinoma is currently debated. Chronic inflammation is a mutagen factor confirmed in the cancerogenesis of various tumours. Aim of the present study was to evaluate, in an objective and consecutive way, with 24h multi-electrode pH-metry the presence of proximal and distal oesophageal reflux in(More)
OBJECTIVE The pharyngocutaneous fistula (PCF) is a serious complication after total laryngectomy, and its etiology is not well understood yet. The aim of our study was to evaluate predisposing factors, incidence, and management of this complication. STUDY DESIGN AND SETTING This was a retrospective study of 268 patients who underwent total laryngectomy in(More)
