Early identification of fetuses with chromosomal abnormalities enables health care providers to form an appropriate management plan for each patient. The main objective of this study was to determine the role of ultrasonography in screening and identifying fetuses at risk for chromosomal abnormalities. A retrospective review of 6480 patients from the Obstetrics and Gynecology ward of Firou...

One of the major causes of spontaneous abortion before the fourth month of pregnancy is chromosomal abnormalities. We report an unusual case of a familial balanced chromosomal translocation in a consanguineous couple who experienced 4 spontaneous abortions. Chromosomal studies were performed on the basis of G-banding technique at high resolution and revealed 46, XX, t (16 6) (p12 q26) and 46, X...

Background: Chromosomal aberrations can be one of the causes of fertility problems, including infertility or frequent abortions. Identification of chromosomal aberrations by clinical diagnostic techniques has been primarily performed through standard karyotyping. In this screening, the prevalence of these disorders were checking in individuals with fertility problems from west population of Ira...

Background & Aims: Chromosome abnormalities are a major cause of miscarriage and neonatal mortality. The present study aimed to determine the association of fetal and parents chromosomal abnormalities with congenital anomalies. Methods: A cross-sectional study was performed in a tertiary referral center (Afzalipour Hospital) over 16 months period (2011-2012). The study groups consisted of 77 fe...

Background: Nonlethal genetic damage is the basis for carcinogenesis. As various gene aberrations accumulate, malignant tumors are formed, regardless of whether the genetic damage is subtle or large enough to be distinguished in a karyotype. The study of chromosomal changes in tumor cells is important in the identification of oncogenes and tumor suppressor genes by molecular cloning of genes in...

Background and purpose : Ït is clearly shown that ionising radiations induce various kinds of DNÂ damages majority of which as sub-lethal damages, are repaired but still some of them are left urepaired and lead to chromosomal aberrations. These chromosomal aberrations in radiation workers, who are occupationally exposed to radiation,could be assayed with cytogenetic evaluation methods.These c...
