Iodine-123 single photon emission computed tomography (SPECT) imaging of the thyroid was performed in two patients with multinodular goiter and swallowing difficulty to provide the functional and anatomic orientation of the goiter in relation to the airway. Transaxial slices showed the retrolaryngeal extension of the enlarged thyroid and the tracheal compression by the goiter in both patients. ...

The primary tracheal cancers are very rare, and squamous cell carcinoma is its most common form, especially in smokers. Due to the late presentation of symptoms, these tumors are usually diagnosed too late, and thus, they have poor survival. The gold standard protocol for these cancers is surgical excision and adjuvant radiotherapy. Primary radiotherapy is applied for the advanced and inoperabl...

BACKGROUND To evaluate the role of radiotherapy (RT) as an adjuvant or definitive treatment in primary tracheal adenoid cystic carcinoma (ACC) for local tumor control and survival. METHODS A retrospective chart review was performed in 22 patients treated with adjuvant or definitive RT for primary tracheal ACC at a single center between November 1994 and December 2008. RESULTS Thirteen and 9...

Oesophageal cancer located above the level of the tracheal bifurcation is frequently complicated by its spread into the airways and by the simultaneous occurrence of malignant bronchial tumours. Although bronchoscopy is an essential procedure in identifying malignant tumoral invasion of the airways and detection of primary airway tumours in patients with suprabifurcal oesophageal cancer, its ro...

background: hemodynamic instability is common during tracheal intubation. the primary purpose of the present study is to evaluate the effect of different doses of remifentanil added to propofol on the hemodynamic profiles during tracheal intubation. methods: ninety patients, 40 to 70 years old, undergoing coronary artery bypass graft surgery under general anesthesia were randomly allocated into...

Background The Brazilian National Cancer Institute (INCA) estimated last year almost forty thousand new cancer cases of laryngeal carcinoma, melanoma, tracheal, bronchial and lung cancer. It is known that multidrug resistance and unspecific toxicity are the major challenges for commercial anticancer drugs [1]. In this regard, natural compounds and derivatives are considered as a source of novel...

Adenoid cystic carcinoma, also called cylindroma, is the second most common histological type of tracheal malignancy but represents 1% of all respiratory tract cancers. We report a case of a 59-year-old patient submitted to an incomplete resection of the trachea and subsequently treated with adjuvant tomotherapy. There have been no reports in the literature regarding intensity-modulated radiati...
