The sugarcane is a crop of annual cycle, where its large water demand is not always full, causing stand gaps in the sprouting of ratoons. Thus, this study aimed to assess the stand gaps in the first and second ratoon sugarcane under seven levels of water deficit. The experiment was conducted in the Center of Agricultural Sciences of the Federal University of Alagoas in the period of 22 February 2010 to 20 February 2012. The stand gaps depending on water depths ranged from 11.2 (25% ETo) to 16.8% (100% ETo) in the first ratoon and from 24.8 (0% ETo) to 32.8% (100% ETo) on second ratoon. The average size of stand gaps ranged from 0.60 to 0.68 m in the first ratoon and from 0.70 to 0.74 m on second ratoon. The average distance to find a stand gap ranged from 16.8 to 29.5 m in the first ratoon and from 6.5 to 10.9 m in the second ratoon. The percentage of gaps and the average size of the gaps in the sprouting of ratoon increase with the age of the sugarcane plantation and the average distance between gaps decreases. The use of irrigation in the culture of sugarcane increase the percentage of gaps, but because these spaces are filled with culms of other sugarcane clumps and were irrigated with larger water depths, the agricultural productivity of the culture increases. The depths of irrigation decreases the average distance between gaps with more intensity in the first than in the second ratoon.

Syphilis in pregnancy is a public health problem, responsible for the high intrauterine mortality rates. This article aims to present a review of historical and epidemiological aspects, clinical manifestations, diagnosis, the treatment of maternal and congenital syphilis, and its perinatal repercussions. The manuscript also describes the Brazilian main policies in public health care for pregnant women with syphilis and for congenital syphilis eradication. The set of words used were “congenital syphilis”, “syphilis in pregnancy” and “syphilis prenatal care”. The databases searched were PubMed (National Library of Medicine - USA), SciELO (Scientific Electronic Library Online), LILACS (Latin American and Caribbean Health Sciences), PAHO (Pan American Health Organization), IBECS, and WHOLIS Cochrane Library, from 1980 to 2011. Fifty-six articles were included in this review, 18 institutional technical manuals, two textbooks and 36 articles relating to maternal and congenital syphilis. The present review showed that there is a gap between intention and action needed to control and eradicate the disease especially with regard to the expansion of access, not only in relation to the number of visits recommended male gender, it is important to assess the quality of their content as well as the actions to be carried out between appointments.
