Maternal Serum and Cervicovaginal IL-6 in Patients with Symptoms of Preterm Labor.

BACKGROUND: Preterm birth is a common problem in obstetrics. OBJECTIVE: To measure maternal serum interlukin-6 in mothers with preterm uterine contractions and compare it with cervicovaginal interlukin-6 in the same women. METHODS: In this cross-sectional study, we measured interlukin-6 in the sera and cervicovaginal fluids of 86 women with preterm uterine contractions. All participants had an intact membrane. Interlukin-6 was measured by using ELISA method. Statistical analysis was done using U-Mann Whitney, Chi-Square and Kendall's tests. RESULTS: The mean and median (Quartile25, Quartile75) of interlukin-6 in cervicovaginal fluid was higher than maternal serum interlukin-6. There was a statically significant difference in the median of interlukin-6 in sera and cervicovaginal fluid (P<0.0001). There was no significant correlation between serum and cervicovaginal interlukin-6 (r=0.048, p=0.548). CONCLUSION: We found no relationship between serum interlukin-6 and preterm labor and the maternal serum Interlukin-6 does not seem to be a suitable biomarker for predicting preterm delivery.

The effect of lemon inhalation aromatherapy on nausea and vomiting of pregnancy: a double-blinded, randomized, controlled clinical trial.

BACKGROUND: Nausea and vomiting of pregnancy are amongst the most common complaints that effects on both the physical and mental conditions of the pregnant women. Due to the increasing tendency of women to use herbal medications during pregnancy, the effect of lemon inhalation aromatherapy on nausea and vomiting of pregnancy was investigated in this study. OBJECTIVES: The aim of this study was to determine the effect of lemon inhalation aromatherapy on nausea and vomiting during pregnancy. MATERIALS AND METHODS: This was a randomized clinical trial in which 100 pregnant women with nausea and vomiting who had eligibility criteria were randomly divided into intervention and control groups based on four- and six-random block sampling method. Lemon essential oil and placebo were given to the intervention and control groups, respectively, to inhale it as soon as they felt nausea. The nausea, vomiting, and retch intensity were investigated 24 hours before and during the four days of treatment by means of PUQE-24 (24-hour Pregnancy Unique Quantification of Emesis). RESULTS: There was a statistically significant difference between the two groups in the mean scores of nausea and vomiting on the second and fourth days (P = 0.017 and P = 0.039, respectively). The means of nausea and vomiting intensity in the second and fourth days in the intervention group were significantly lower than the control group. In addition, in intragroup comparison with ANOVA with repeated measures, the nausea and vomiting mean in the five intervals, showed a statistically significant difference in each group (P < 0.001 and P = 0.049, respectively). CONCLUSIONS: Lemon scent can be effective in reducing nausea and vomiting of pregnancy.

Effect of body mass index on severity and prevalence of varicocele.

Varicocele is classified as grade I-III regarding its severity. This study was aimed to determine the correlation between height and weight with varicocele grade in 18-30 years age group. We enrolled 400 persons aged 18-30 years referred to the specialist's clinics of Tabriz Medical Sciences University or Medical Commission Since Sep. 2004 to Mar. 2005. First we divided the volunteers in two groups including Varicocele Group and Non-varicocele Group, then varicocele patients were classified to three grades considering the severity of the disease: severe (Grade III), moderate (Grade II) and mild (Grade I). Finally, the correlation between height, weight and Body Mass Index (BMI) was evaluated. There was a significant relation between height and grades of left-side varicocele; in other words the severity of disease was increased with height (p = 0.004). Also, height increased the prevalence ofvaricocele (p = 0.011). On the other hand, low weight and BMI increased the prevalence of varicocele (p = 0.000, p = 0.004) but did not affect the severity of disease (p = 0.364, p = 0.172). In conclusion, the height of patients directly affected the prevalence and severity of left-side varicocele which probably is related to length of left internal spermatic veins in these patients and increased hydrostatic pressure in taller patients. Also, the weight and BMI is effective on the prevalence of varicocele. It seems that slim and tall persons will benefit from evaluation while puberty.
