The relationship between physical activity at home and at work during pregnancy and preterm birth was studied. Using a case-control design, 99 women who delivered preterm were compared with 189 women who had term deliveries. The risk of preterm birth was tested in relation to characteristics of work in and outside the home. All women were interviewed post-partum before discharge.

There were no statistically significant differences between the groups in relation to sociodemographic and obstetrical factors, but level of education was significantly lower in the study group versus the control group (p=0.001).

Women who delivered preterm had devoted less time 3 months prior to delivery to household chores (mean of 3.7 hours vs. 4.8 hours in the control group, p=0.002). They also had spent less time walking around the home than the controls (1.2 vs. 1.5 hours, p=0.02). There were no differences between the groups in relation to physical activity outside the home, not during working hours, nor in duration of work. Significantly fewer women who delivered preterm were active in sports (odds ratio 0.22; 95% confidence interval 0.50-0.65; p=0.002).

A low level of education was significantly related to the risk of preterm birth, which may have resulted from lesser compliance with their physician's recommendations. It appears that in women not used to significant physical activity but who had access to adequate prenatal care, physical effort during pregnancy was not related to a higher risk of preterm birth.

Anaphylactic Shock after Diclofenac Sodium

Anaphylaxis due to diclofenac sodium (Voltaren) is rare. We describe a 39-year-old woman who received a suppository of diclofenac for analgesia 6-hours after cesarean section. She developed severe angioedema and profound hemodynamic shock 10 minutes after the diclofenac, to which she had been exposed in the past without any side-effects. There are few reports of such an acute, life-threatening, multisystem reaction to this drug in the English literature.

Brucellosis in Pregnancy

Brucellosis is rare in pregnancy. Recently, an increase in the incidence of this disease has been observed in our area. We present 7 cases of brucellosis in pregnancy and review the literature on the effects of brucellosis on the outcome of pregnancy. Brucellosis is rare in the Middle East and Africa and the most common source of infection is unpasteurized milk products. Brucella is a coccobacillus, gram-negative bacterium, whose hosts are mostly animals.

There is controversy about the relationship between brucellosis and the outcome of pregnancy. There is some evidence that there is a higher rate of complications such as abortion, premature rupture of membranes and preterm delivery in infected animals. Reasons for this difference in the impact of brucella in animals and man include the absence of the carbohydrate erythritol in the human placenta, which appears to be a preferential medium and growth factor for brucella in the placentas of animals.

There is uncertainty regarding effects of brucella in early pregnancy and no evidence of its transplacental passage in later pregnancy, causing adverse obstetrical outcome, although recently there has been a single report of Brucella abortus (biotype 2). 
We present 7 cases of brucellosis in pregnant women found between 1977-1988. Its incidence among the women who delivered here is 0.007% (7/92,768 deliveries). Our first case was complicated by preterm premature rupture of membranes and preterm delivery in the 20th week of gestation. In 2 other cases there was preterm delivery with 1 developing clinical chorioamnionitis. The 4 remaining women delivered at term, although 1 had preterm premature rupture of membranes and intra-uterine growth retardation, and 2 had postpartum endometritis.

Acute appendicitis is the most common surgical problem in pregnancy, when it is difficult to diagnose early because of the physiological changes of pregnancy. We studied the problem in the Negev population and present the main issues in diagnosis and management. Between 1988-96, 26 women were operated on for acute appendicitis during pregnancy (1/3297 deliveries), 3 by laparoscopy. In 13 there was a histopathological confirmation of the diagnosis. Clinical diagnosis was more accurate in the first trimester of pregnancy than in the second or third (p=0.073). Premature delivery rate was higher in both confirmed and unconfirmed acute appendicitis than in other pregnancies (p<0.00001), but without significant differences between the 2 groups with appendicitis. Other indexes of maternal and perinatal morbidity did not differ either.

Parturient Compliance in Intra-Partum Epidural Analgesia

The relationship between parturients' sociodemographic characteristics and the tendency of the medical staff to offer and of the parturients to accept intrapartum epidural analgesia, was investigated. 97 Jewish parturients were interviewed during January 1996. Multiple logistic regression analysis was used to evaluate the statistical significance of the results. 10 parturients (10.3%) asked for intrapartum epidural analgesia, and while 46 (47.4%) were offered it, only 22 (22.7%) accepted. Epidural analgesia was mostly offered to, and accepted by: low birth-order parturients (1st-3rd delivery), those belonging to the upper middle class, and to parturients with higher compliance with prenatal diagnostic tests. There was no significant association between the tendency of the medical staff to offer epidural analgesia to secular as compared to traditional parturients.

We conclude that the use of intrapartum epidural analgesia is related to various maternal sociodemographic characteristics. If the low compliance with epidural analgesia is related to prejudice and unfounded fears, we recommend that the benefits of this type of analgesia be explained before birth in the antenatal clinics.

Food-withdrawal has been proposed as a possible mechanism for initiating the onset of labor in animals and humans. The hypothesis was based upon the reported increase in deliveries of infants during the Yom Kippur fast. We studied the effect of the fast on full term deliveries of Jewish women, with non-fasting Bedouin women as controls (1988-1995, 1,313 Jewish and 1,091 Bedouin deliveries). To determine the effect of Yom Kippur itself, delivery rates on Sukkot and Yom Kippur were compared in both groups. The mean delivery rate in the Jewish population was significantly higher during Yom Kippur and the day after, than during the 7 days before Yom Kippur (15.1±5.1 and 14.6±4.7 vs 10.7±3.5, p<0.04 and p<0.01, respectively). There was an increase in delivery rate during the 6 hours before the end of the fast. In the Bedouin women there were no changes in delivery rate during any of these periods. There were no significant differences in the rates of deliveries during the Sukkot festival between Jewish and Bedouin women. We conclude that fasting is associated with a significant increase in the rate of deliveries at term.
