Neonatal screening for congenital hypothyroidism in an Italian Centre: a 5-years real-life retrospective study.

Introduction: Congenital hypothyroidism is an endocrine disease with a significant incidence in the general population (1:2000-1:3000 newborns in Italy) and a different geographical distribution, partially explained by endemic iodine deficiency, genetic traits and autoimmune thyroid diseases.

Objectives: Aims of this study are: to evaluate the incidence of positive neonatal blood spot screening for CH in western Sicily, identified by the screening centre of the Children Hospital "G. Di Cristina", ARNAS, Palermo; to evaluate the impact of a lower TSH cutoff in the neonatal blood spot screening for CH.

Expression of wild-type and variant estrogen receptor alpha in liver carcinogenesis and tumor progression.

Although estrogen receptors (ERs) are expressed in human hepatocellular carcinoma (HCC), several clinical trials have failed to demonstrate the efficacy of antiestrogen treatment in HCC patients. Recently, the identification of several ER splicing variants has enlightened the complex nature of estrogen signaling in peripheral tissues; this may help understanding estrogen role in either nontumoral or malignant nonclassical target organs, including liver. In this work we have investigated mRNA expression of wild-type and splice variants of ERα in nontumoral, cirrhotic, and malignant human liver, as well as in HCC cell lines, using an exon-specific reverse transcription polymerase chain reaction (RT-PCR).

Endocrine therapy in metastatic breast cancer: data from Breast Cancer Registry of Palermo, 1999-2005 .

This study compares the survival of breast cancer patients who are metastatic at diagnosis (DMBC) and of recurrent metastatic breast cancer (RMBC) patients. We analyzed retrospectively the population-based data of Breast Cancer Registry of Palermo and collected a total of 4459 breast cancer cases in the years 1999-2005. Survival analysis did not show statistically significant differences between DMBC and RMBC patients (P= 0.
