Measurements of Blood Pressure, Oedema and Proteinuria in a Pregnant Population of New Zealand

Summary: This is the first report of the largest study of blood pressure measurement in pregnancy in a New Zealand population using standardized definitions and methodology. Over 3,800 women who delivered in an 8-month period in the Wellington region were included in the study. Blood pressure measurement and the presence of oedema and proteinuria were recorded from booking until delivery and in the puerperium. Only 2.7% of women were unable to be contacted after delivery for details on outcomes. The results established normal ranges for blood pressure throughout pregnancy. The data show that Mood pressure greater than 140/90 until 35 weeks' gestation is outside 2 standard deviations at all gestations and justifies using these measurements as the definition of hypertension in pregnancy. The fall in blood pressure in the 2nd trimester was less than 1 mm Ffg per week in both the systolic and diastolic pressures. This fall was smaller than previously recorded in other studies. Gestational hypertension was the commonest blood pressure abnormality occurring in 15.2% of the population. This represented 69% of the pregnant women with a hypertensive disorder. The overall incidence of both gestational hypertension and preeclampsia was 18.5% which is higher than reported in other parts of the world. In this study obesity was significantly associated with hypertensive disorders in pregnancy. An arm circumference of >33 cm, one of the measurements of obesity, was found in 6.8% of the study population. Even after the effect of arm circumference was taken into account, hypertensive disorders were also more common in Pacific Island women. Ankle oedema was significantly associated with the development of both gestational hypertension and preeclampsia but the incidence of oedema was noted in only 11.9% of the subjects.     

Ketoprofen Versus Paracetamol in the Treatment of Acute Migraine

The efficacy and safety of ketoprofen and paracetamol were compared for the treatment of acute migraine in a randomized, double-blind study of 64 patients. Thirty-four patients received ketoprofen 100 mg intramuscularly, and 30 patients received paracetamol 500 mg intramuscularly. Partial or complete relief of pain and other symptoms was achieved 15 to 20 minutes after administration in the ketoprofen group and within 35 minutes in the paracetamol group. Complete relief of pain was achieved within 30 to 40 minutes after ketoprofen in 28 patients (82.5%) compared to 5 patients (17.5%) in the paracetamol group. Six of the patients treated with ketoprofen needed a second dose for complete relief of pain during the 4-hour follow-up period. Side effects were rare and minimal. Our findings suggest that ketoprofen produced statistically significant benefit in the treatment of acute migraine.     

细胞凋亡抑制因子（Fas／APO-1）与抗β2-肾上腺素能受体自身抗体的关系

目的 检测并比较心肌梗死急性期不同时间点，β2自身抗体阳性组与阴性组，患者血清中Fas／APO-1水平差异，了解β2自身抗体对Fas／APO-1的影响。方法 41例急性心肌梗死患者，分别于发病24h、7天、2～4周时取血，采用ELISA的方法，检测血清中β2自身抗体的阳性率以及Fas／APO-1的水平；另外取34位性别、年龄匹配的健康人的血同法检测Fas／APO-1作为对照。结果心肌梗死急性期Fas／APO-1的水平均高于对照组（P〈0．05），以梗死后24hFas／APO-1的水平为最高；心肌梗死急性期不同时间点，β2自身抗体阳性组Fas／APO-1的水平均高于阴性组，但两组的结果差异无显著性（P〉0．05）。结论 血清Fas／APO-1水平可以在一定程度上反映心肌细胞凋亡的变化趋势，β2自身抗体对Fas／APO-1的确切影响，有待更大规模的实验来证实。
