Abstract
Background: Intra-rater agreement in observing and decision making in diagnosis of any disease is of great importance.This investigation is to observe and read ultrasound pictures of ovarian cysts and distinguish its category for any radiologist. Distinguishability is one of the related entities in this matter and radiologists&apos ability in correct diagnosis is of great concern. In this study, we evaluated radiologist’s distinguishability of ordered categories of ovarian cyst diseases (benign, borderline and malignant) in ultrasonography. To do this, we measured intra-rater agreement of radiologists by Weighted Kappa coefficient, and then by the help of “square scores association model” and “agreement plus square scores association model” we evaluated their distinguishability in diagnosis of the severity of the ovarian cyst’s diseases.
Methods: In this analytical cross-sectional study, two radiologists and three radiology residents assessed ultrasounds of 40 patients separately and independently in two periods (with the interval of one week). Patients selected from those who were referred to Mirza Koochak Khan Hospital in January 2005. Ultrasounds were performed by an expert radiologist and by a single apparatus.
Result: Data from radiologists was evaluated by “square scores association model” due to their superior results of distinguishability. Mean of Weighted Kappa coefficient was 0.81 and intra-rater agreement was 0.99 for our radiologists, but due to weaker results of our residents, we used “agreement plus square scores association model” for analyzing and mean of Weighted Kappa coefficient was 0.65 and intra-rater agreement was 0.97 for them.
Conclusion: Although radiologists had a better function than their residents, all of them showed appropriate distinguishability and intra-rater agreement in diagnosis and categorizing of the ovarian cyst’s disease. To distinguish benign category from borderline was more difficult than to distinguish malignant category from borderline and radiologists showed better results in this than their residents did.

Abstract
Background: Dental amalgam, a mixture of approximately 50% mercury with silver, tin, zinc and copper in varying ratios, is a major source of mercury pollution in the general population not occupationally exposed. The toxicity of mercury is enhanced because it is so readily absorbed, with around 90-100% of mercury vapor being absorbed through the oral mucosa. The aim of the current study is to examine the mercury levels in hair and nails in subjects with amalgam fillings.
Methods: For a sample of forty university students reporting infrequent fish consump-tion, with their only known exposure to mercury from amalgam fillings, mercury levels were measured in hair and nail samples using the LECO AMA 254 Advanced Mercury Analyzer (USA), according to the ASTM standard No. D-6722 test method.
Results: Mercury concentration in hair ranged from 0.09 to 3.11 mg/kg, and in nail from zero to 1.35 mg/kg. We found that subjects with five or more amalgam fillings had significantly higher levels in their hair than subjects with zero to 5 amalgam fillings (CI 95% P=0.003). However, the number of amalgam fillings had no effect on the mercury concentration in nails in these two groups (P=0.26). There was no significant difference between the levels of mercury of males and that of females tested (P=0.26 for nail and P=0.15 for hair).
Conclusion: The mercury amount in hair was 1.5 times as much as that of the nail samples, may be due to the differences in the chemical compounds, particularly those with sulfur, or the deposition of those compounds that would be affected by blood circulation during formation of hair and nails. Although the amounts of mercury found in this study were below the WHO maximum acceptable level of 6 mg/kg for mercury in human hair, the levels were sufficient to warrant the use of other dental materials such as composites in order to decrease the overall rate of exposure to mercury.

Abstract
Background: Sexual function in women may be affected by their menstrual cycle. Lack of sexual drive is a deficiency or absence of sexual fantasies and desire for sexual activity. This study aims at determining the changes in sexual desire during the menstrual cycle and those associated with premenstrual syndrome (PMS) and evaluates sexual desire during the menstrual cycle and the associated changes with PMS.
Methods: The sample for this cross-sectional study includes 150 women employed in factories in Tehran. The instruments for data collection were questionnaires and journals of premenstrual experiences.
Results: Analysis of the data showed that the mean age of the subjects was 31 years )standard deviation = 8.46(. The most frequent decrease in sexual desire was during the week prior to the start of menstrual bleeding (27.3%) and the least frequent was from the end of bleeding to one week before the next period of menstrual bleeding (5.3%). In 24.7% of the cases, an increase in sexual desire occurred during the middle of the menstrual cycle and 27.3% during the course of menstrual bleeding. Moreover, 10.7% of the subjects had an increase in sexual desire during the week before bleeding. Furthermore, a positive correlation was found between changes in sexual desire and PMS (p<0.001). In addition, a positive correlation was found between changes in sexual desire and breast tenderness, joint and muscle pain.
Conclusions: The sexual desire of women, with or without PMS, changes during the menstrual cycle. The greatest decrease in sexual desire occurs during the first week before menstrual bleeding in women with PMS. Such information can greatly help toward understanding and treatment in sexual therapy for couples.

Background: Gestational diabetes mellitus is diagnosed as carbohydrate in tolerance demonstrated
for the first time in the course of pregnancy. The aim of this study was to evaluate
the selective screening method for gestational diabetes mellitus (GDM)
based on: 1- recommendation of
the fourth workshop- conference on GDM 2-
evaluation of risk factors
Methods: A case-
control study was performed on 370 pregnancies inflicted
by GDM in Hazrat
Zaynab
Hospital,
Shahed
University.
The maternal and perinatal outcomes and prevalence of risk factors based on recommendation
of the fourth workshop- conference on GDM
in these women with GDM were compared with the
same data and risk factors of randomly selected 600
pregnant women at the same time and in the same hospital, they all underwent
universal testing for GDM, and their OGTT
were normal.
Results: The prevalence of all risk factors was significantly higher in the group with GDM,
but 45 of these women (12%)
had no risk factors. 107 women (29%)
with GDM were at low risk and would remain undiagnosed
if selective screening method was used. The
main neonatal complications in the low- risk group did not differ from the
complications in other women with GDM.
Conclusions: The
universal screening of all pregnant women seems to justified whereas the
recommendations for not screening low- risk group are doubtful and require further
examination.

Background: Preterm delivery is a relevant public health problem since it is an
important factor determinant of morbidity and the main reason for neonatal
mortality. Many publications have pointed at clinical methods, biological,
biochemical and ultrasonographic markers, which applied in combination or on
their own, aim at predicting spontaneous preterm delivery. Transvaginal
sonography is an effective method for the study of uterine cervix during
pregnancy since it permits to assess the cervical morphology and biometry in
detail with a high degree of reliability. The aim of this study
was to evaluate the association between spontaneous preterm delivery (SPTD) before 35 and 37 weeks of gestational age, in high risk population and the measurement of
the cervix length and cervical funneling.
Methods: A prospective cohort of 200 women carrying high
risk pregnancies were evaluated by transvaginal sonography between 14th and 28th weeks of gestation.
Results: Cervical length less than 18mm before 35th and 37th weeks of gestational age and the presence
of cervical funneling presented a satistically significant association with
spontaneous preterm delivery before 35 weeks. The cervical length with less 18 mm demonstrated a strong association with SPTD before 37 weeks (p<0.005 OR=92.15) and before 35 weeks' gestation (p<0.001 OR=32.33). The logistic regression analysis suggested the
cervical length with less than 18mm as the only variable that revealed satistically significance association
with SPTD.
Conclusion: The results seem to indicate
that the assessment of cervical length is an important ultrasound marker for
predicting spontaneous preterm delivery.
