To determine how often ingested foreign bodies are found and what parameters may predict their retrieval.
During 1 year, we prospectively studied all patients referred to our Ear Nose and Throat Emergency Unit because of foreign body ingestion.
During the study, 204 (median age-42 years [10 months-84 years]) patients were admitted because of ingested foreign body. The most common was fish bone (88%). Most patients were admitted <24-hour after ingestion (72%) and complained of symptoms above the cricoid cartilage (79%). A foreign body was removed by Ear Nose and Throat team in 108 (53%) patients. Twenty-three (11%) patients were referred to Gastroenterology....

The management of cervical lymph node metastases from an unknown primary tumor remains a controversial subject. Recently, Positron Emission Tomography (PET) has proved useful in the detection of these tumors, even after an unsuccessful conventional diagnostic workup. This study was performed to assess the role of PET in the detection of occult primary head and neck carcinomas.
A retrospective analysis of a four year period at a tertiary referral oncology hospital was conducted.
Of the 49 patients with cervical metastases of carcinoma from an unknown primary, PET detected a primary in 9 patients and gave 5 false positive and 4 false negative...

OBJECTIVE: The transmission of the gastric pathogen Helicobacter pylori involves the oral route. Molecular techniques have allowed the detection of H. pylori DNA in samples of the oral cavity, although culture of H. pylori from these type of samples has been sporadic. Studies have tried to demonstrate the presence of H. pylori in adenotonsillar tissue, with contradictory results. Our aim was to clarify whether the adenotonsillar tissue may constitute an extra gastric reservoir for H. pylori.
METHODS: Sixty-two children proposed for adenoidectomy or tonsillectomy were enrolled. A total of 101 surgical specimens, 55 adenoid and 46 tonsils, were obtained. Patients were...
