Acinic cell carcinoma of minor salivary gland origin

The occurrence of acinic cell carcinoma in the minor salivary glands appears to he exceptional. A review of the English language literature revealed about 80 previously reported cases. In this paper. the clinical behaviour and pathological findings in three cases are reported. The tumours took their origin from the hard palate, soft palate and lower lip. The three cases presented with malignant clinical behaviour; all three recurred. In one case the local recurrence was multinodular with capsular infiltration. Two cases developed regional lymph node metastasis, and one metasized to the lung and liver. In one the tumour infiltrated bony structures, and nerve in another. These cases tend to support the belief of some authors that acinic cell ‘tumours' are clinically malignant and should be included in the carcinoma grou

Can informality explain inequality? The case of Mexico, 1987-1999

In this paper we contrast the impact of the income gap between formal and informal sector on Mexico's income inequality to alternative explanations. Unlike previous studies we take a time series approach to analyze the determinants of income inequality for the period 1987-1999. We find that an increase in the wage gap between the formal and the informal sector and in the wage gap between the higher educated and the lower educated people leads to an increase in inequality. Inequality seems to be counter-cyclical, that is, an increase in output leads to a reduction in inequality. An unexpected result is that inequality declines when output is below its long term trend. We obtained mixed results about the role played by prices and inflation on inequality
