[Update on delayed births].

Sixteen (16) cases of delayed births have been reported in the literature. All of these patients obtained at least one live child. This method can, therefore, be suggested in cases of premature birth after less than 28 weeks of amenorrhea for patients who present with a multiple, pluriamniotic pregnancy.

[Birth delayed by 23 days after premature delivery in a triplet pregnancy obtained by in vitro fertilization].

At 26 weeks' gestation, the patient gave birth to 2 premature infants who did not survive. Following this delivery, under general anaesthesia and infusions of tocolytic drugs and antibiotics the uterus was washed with Ringer's lactate solution and cerclage of the cervix was performed after ligation and section of the two umbilical cord flush with the cervix. The "second delivery" was delayed by 3 weeks; the child weighed 1,150 grams at birth and survived. Six similar cases (including ours) have been published, and in each of them one living child was obtained. The above technique can therefore be recommended, in case of premature delivery before 28 weeks of gestation, for women with multiple pluriamniotic pregnancy.

[Occurrence of Coxiella burneti in foodstuffs in animal origin].

Some of the organs and secretions from Q fever infected cattle originally intended for human consumption were tested for their Coxiella content. In the cows, the udder and udder lymph nodes were found to contain over 75% of the exciters; the exciters were also found to a large extent in the milk, reaching levels of between 10(1) and 10(5) Inf. E/ml milk. On the other hand, other parts of the animal used as meat were less infected. Lymph nodes in the body contained 28%, liver, kidney, pancreas and lungs 25% and musculature (meat) 8%. Udder infections in cows can last for months or even years, but they persist only for a few weeks in sheep. Treatment and preservation methods used on the meat after the animals is slaughtered also decimate the exciters, thus decreasing any risk to the consumer. Infected milk also loses its capacity for infection when sufficiently pasteurised, though the problem of oral infection in fresh milk still exists. Tests on guinea pigs show that when they are fed fresh milk containing Coxiella the formation of blood antibodies can take place, and also infestation of the organs. Essential conditions for this can be found in the exciter content, the virulence of the exciters and a weak defence mechanism in the organism.

The significance of martens as transmitters of wildlife rabies in Europe.

In two areas of the Federal Republic of Germany, 191 rabies cases in martens were investigated for the occurrence of clusters. The length of the interval between cases recorded in the same community showed an uneven distribution. Most such cases occurred at intervals of less than 6 months. No close correlation was found between such associated cases in martens and the frequency of cases in foxes. The results suggest that short chains of infection do occur in martens. Though these episodes in martens are rare and tend to cease after 3-4 months, their significance in the epidemic should be considered locally during the final stage of control operations.
