Occupational dermatitis in animal feed mill workers.

In an epidemiological study of occupational dermatitis in 15 different northern Italian animal feed mills, 204 workers were interviewed, examined and patch tested to 34 allergens, selected from the additives most commonly used in the animal feed mills under consideration. The prevalence of occupational contact dermatitis was 13.7% (28/204): 7.8% (16/204) irritant contact dermatitis and 5.8% (12/204) allergic contact dermatitis from animal feed additives. Among the latter, there were sensitizations, to our knowledge hitherto unreported in the literature: to indigo carmine (2 cases), monensin sodium (1 case), thiabendazole (1 case), methylchlorpindol (1 case) and amprolium hydrochloride (1 case). 3.9% (8/204) of the workers complained only of pruritus sine materia on exposed areas of the body. Contact dermatitis increased with respect to duration of employment: the difference in the rate of contact dermatitis between workers employed in animal feed mill for greater than 10 years and those employed for less than 10 years was statistically significant (p less than 0.05). 6.8% (14/204) had latent sensitivity, which was more frequent in workers with less than 1 year of employment with respect to more experienced colleagues.

Iso-intense gallium uptake in hepatocellular carcinoma: potential pitfalls in diagnosis.

Twenty-one patients with hepatocellular carcinoma who had gallium scans were retrospectively reviewed. Four of them demonstrated iso-intense gallium uptake compared to the adjacent liver parenchyma. The importance is therefore emphasized of using radiocolloid scan with tracer angiogram performed at the same time in order to avoid the potential diagnostic pitfall of not recognizing the tumor on gallium scan alone.

Accuracy of epiluminescence microscopy among practical dermatologists: a study from the Emilia-Romagna region of Italy.

AIMS AND BACKGROUND: The accuracy of epiluminescence microscopy (ELM) for pigmented skin lesions (PSLs) is still unclear. The large scale utilization of the technique is generally discouraged. The present study was aimed at comparing the accuracy of ELM with that of clinical examination alone in a group of 20 practical dermatologists. METHODS AND STUDY DESIGN: Thirty digital clinical images of benign and malignant PSLs and their digital ELM counterparts were used. A set of cumulative accuracy measures reported in the combined clinical/ELM diagnosis was compared with that reported in the clinical diagnosis alone. RESULTS: The proportion of nonmelanocytic lesions (NMLs), melanocytic nevi, and melanomas correctly identified, the predictive value of such diagnoses, and the proportion of melanomas detected by referral for biopsy (irrespective of the diagnosis reported) increased significantly. The cases referred for biopsy despite a "benign" impression decreased significantly among NMLs. CONCLUSIONS: The observed tendency towards a greater accuracy suggests that even in the routine dermatology practice ELM has the potential to improve the clinical examination of PSLs.
