Cell-free fetal DNA in amniotic fluid supernatant for prenatal diagnosis.

In widespread conviction, amniotic fluid is utilized for prenatal diagnosis. Amniotic fluid supernatant is usually discarded, notwithstanding being a good source of fetal DNA. The aim of the present study was to assess cell-free fetal DNA extracted from amniotic fluid supernatant for application in prenatal diagnosis such as gender determination and early diagnosis of ß-thalassemia. Samples of amniotic fluid of 70 pregnant women were collected and went through routine tests along with tests for cell-free fetal DNA from amniotic fluid supernatant. The DNA in the amniotic fluid supernatant was extracted and analyzed for gender determination by PCR and Real-time PCR. ARMS-PCR was applied to test early diagnosis of IVS II-I mutation (common ß-thalassemia mutation) and E7V mutation for sickle cell anemia using DNA extracted from the amniotic fluid supernatant. Using the cell-free fetal DNA extracted from the amniotic fluid supernatant, the sensitivity of PCR and Real-time PCR for gender detection was compared with the routine cytogenetic method. The fetus tested for sickle cell anemia and ß-thalassemia was observed to be healthy but heterozygous for IVS II-I mutation. The findings indicated that cell-free fetal DNA from amniotic fluid supernatant can be a good source of fetal DNA and be used in early prenatal diagnosis since because of its fast and accurate application. Therefore, it would be suggested that the amniotic fluid supernatant's disposal is prevented because if the tests needs to be repeated, cell-free fetal DNA extracted from the amniotic fluid supernatant can be used as an alternative source for prenatal diagnosis.

Beliefs and practices of Iranian pregnant mothers regarding vitamins and minerals.

The objective of this descriptive study was to examine the vitamin and mineral supplements safety beliefs and practices of Iranian pregnant women. Data were collected from 400 randomly chosen women. More than 50% of the participants believed that taking vitamins and minerals during pregnancy was safe; 87% reported taking iron during pregnancy, of which 71.7 % reported their doctor as the main recommender; 21.8% reported first trimester as the most beneficial time for iron supplementation, 13.0% second trimester and 3.0% third trimester. Although an appropriate intake of vitamins and minerals can assure health in pregnancy, excess can be harmful. Educational programmes for women of childbearing age are necessary.

Vulvovaginitis candidiasis recurrence during pregnancy.

Vulvovaginitis is the most common gynecologic condition seen by practitioners rendering primary care to women. Vulvovaginitis Candidiasis (VVC) is the most common type of vaginitis and this study aimed at specifying VVC recurrence during pregnancy. In this prospective study, 150 pregnant women suffering from vaginal excretion, morsus and itching were studied. Initially, the patients were treated using clotrimazole local cream (5 g) for 7 successive days. After initial treatment, the patients were freely visited once a month until delivery considering vaginitis symptoms and VVC recurrence was examined during pregnancy. Mean age of the understudy mothers was 27.26 +/- 3.76. Mean of recurrence number was 0.17 +/- 0.48 during the first trimester. Mean of recurrence number was 0.92 +/- 0.76 during the second trimester. Mean of recurrence number was 2.16 +/- 0.63 during the third trimester. Statistically significant difference was between recurrences during three trimesters of pregnancy (p < 0.001). There is statistically significant difference between mean number of recurrences during three trimesters of pregnancy.
