The cancer of the uterine cervix remains a serious public health problem in developing countries with low social-economic conditions. Papanicolaou smear has been used to screen women for cervical cancer since 1940, and it is widely recognized as an effective method for preventing cervical cancer. In Brazil, conventional Papanicolaou is the most common method used in diagnosis cytopathological routine, involving the morphological cell analysis by microscopic examination of cervical samples smeared on glass slides. On the other hand, the liquid cytology is an advantageous method whose specimen collected is put into a fluid alcohol based to guarantee the potential use of residual cellular material in cytobrush. Moreover, this method permits additional diagnostic studies, preserving the morphological cell features as the conventional one does. The aim of the present study was report the historical evolution of different cervical cytologic tests, emphasizing the advantages and disadvantages between conventional Papanicolaou method and new technologies in liquid based cytology.

HIOMT is a gene that encodes hydroxyindole-O-methyltransfe-rase, the final enzyme in the melatonin synthesis pathway. As the timing of melatonin synthesis is different for morning and evening people, it is possible that polymorphisms in genes coding for the enzymes which participate in melatonin synthesis can influence this hormone synthesis and release patterns that may result in different circadian outputs. The aim of this study was to search for polymorphisms in the HIOMT gene and to verify possible associations between genetic variations in this gene and circadian phenotypes in a Brazilian population sample. Among the 44 extreme morning and the 48 extreme evening people, ten polymorphisms were found, being two of them not described so far. Haploview analyses showed linkage disequilibrium between pairs of polymorphisms in the promoter B region. Also, the haplotype AG (rs4446909, rs5989681) is associated with evening preference. The analysis of these data indicates that polymorphisms in the HIOMT gene exhibit a possible trend to influence circadian phenotypes in this Brazilian population sample, possibly affecting the rate and/or level of melatonin synthesis.
