Oesophageal carcinoma is a relatively rare form of cancer. However, it is also one of the most deadly forms of cancer, with a 5-year survival rate of only 3% for patients with nodal disease, and 42% for those without nodal disease. ⋯ The literature is reviewed in the context of our recent experience. A retrospective review of 129 patients with oesophageal carcinoma, who underwent PET or PET-CT scanning over a 24-month period confirmed the incremental value of PET and PET-CT scanning in the staging of oesophageal carcinoma.

Evaluation of the effects of toluene inhalation on alveolar epithelial permeability by 99mTc-DTPA inhalation scintigraphy in automobile painters.
The main component of paint thinner used in industry is toluene diisocyanate (TDI) which can cause occupational asthma in 5-10% of exposed workers. ⋯ Our results suggested that the clearance of 99mTc-DTPA from the lungs of automobile painters was slower than in the control group, but the difference is not statistically significant. This data also supports the observation that TDI occasionally stimulates bronchial changes rather than alveolar changes in automobile painters.

Evaluation and comparison between pentavalent 99mTc dimercaptosuccinic acid (99mTc(V)-DMSA) and 99mTc-hexamethylpropylene amine oxime white blood cell (99mTc-HMPAO WBC) scintigraphy in the detection and assessment of disease activity in patients with active inflammatory bowel disease (IBD). ⋯ 99mTc(V)-DMSA compared to 99mTc-HMPAO WBC could provide a simple, non-invasive alternative method for the assessment of disease activity, although it is slightly inferior to 99mTc-HMPAO WBC scintigraphy especially in the evaluation of disease localization in IBD patients.
