RESUMEN
Premature birth and low birth weight are regarded as two risk factors for impaired language development. Hence, information about primary period of language development in these children is important for early detection of children's needs during their language development period. The goal of this study was to determine the expressive lexicon size in 18 to 36 month-old premature children with low birth weight and to compare them with their full-term peers. In this prospective historical survey, using form II of the MacArthur-Bates Communicative Development Inventories [CDI], expressive lexicon size of 42 premature children with low birth weight who were 18 to 36 month- old and 42 full-term peers in three age groups with six monthintervals is evaluated. Forms were completed individually by mothers of children. Data analysis showed that the difference in expressive lexicon between the two groups was significant [p=0.025]. Nonetheless, in each group the difference in expressive lexicon size between the three age groups was not significant. The results of this study suggest that expressive lexicon size in premature children with low birth weight was smaller than their full-term matches and the development of lexicon size is delayed in these children. However, by increasing age, these children follow a similar development pattern in terms of lexicon size and eventually catch up with their full term counterparts. This study shows the importance of early intervention to expedite this compensatory mechanism in these children
RESUMEN
Cervical cancer is the third most common malignancy of the female genital tract. The main objective of this study was to determine the risk factors for cervical cancer. Method: This was a case-control study. From a total sample of 263 women, 87 patients with diagnoses of invasive cervical cancer comprised the case group arid another 176 healthy females were in the control group. The location of research was at two oncology referral hospitals of 1sf ahan: Amin and Seyed Al-Shohada. Multiple logistic regression modules were used to analyze the data by SPSS-9 software. The results of the study showed that cervical cancer is related to age at first marriage [OR=5, 95% CI 1.5-16.6; P=O.008], number of deliveries [OR=3.3, 95% CI 1.2-8.8; P=O.02] and type of oral contraceptive used. In connection with duration of using oral contraceptives, the results showed that in those women who used oral contraceptives for a period of >5 years [OR=3.3, P=O.008], the mean number of sexual intercourses per week at four decades of marriage life was more in the case group compared with the control group [P=O.0001]. Socioeconomic status differences were not significant. False negative Pap smear test results were about 15.5%. This study identified some risk factors related to the incidence of cervical cancer i.e. younger age at the first coitus, number of intercourses per week, number of deliveries and duration of oral contraceptive use
