[A rare complication of cholelithiasis. Ulceration of the cystic artery associated with cholecystoduodenal fistula].
We observed a rare complication of gall stones revealed by a paroxysmal digestive haemorrhage. Ulceration of the cystic artery occurred due to a stone trapped in the neck associated with a cholecystoduodenal fistula. This is an exceptional cause of major digestive tract haemorrhage. Treatment is undertaken with that of the gall stone. Most often haemorrhages originating in the bile tract are occult.

[Seasonal, weekly and lunar cycles of birth. Statistical study of 12,035,680 births].
The authors have studied the seasonal, weekly and lunar rhythms which could characterize deliveries, based on 12,035,680 french births, between January 1, 1968 and December 31, 1982. The seasonal rhythm is the most remarkable. It is characterized by a maximum of newborn in May and a minimum in November; there is an increased number of births during the month of September. The weekly rhythm is characterized by a drop in the number of births especially on Sundays, but also on Saturdays, with a maximum on Tuesday. The number of births also fluctuate according to the lunar cycle. Their amplitude is low. They are however significant. From that standpoint, these results confirm other studies already conducted in France and the USA, in a much smaller scale.

[Births, fertility, rhythms and lunar cycle. A statistical study of 5,927,978 births].
Is there any relationship between the times when babies are born and the synodic lunar cycle? There are published works that show that there is such a relationship. We have looked at 5,927,978 French births occurring between the months of January 1968 and the 31st December 1974. Using Fourier's spectral analysis we have been able to show that there are two different rhythms in birth frequencies: --a weekly rhythm characterised by the lowest number of births on a Sunday and the largest number on a Tuesday: --an annual rhythm with the maximum number of births in May and the minimum in September-October. A statistical analysis of the distribution of births in the lunar month shows that more are born between the last quarter and the new moon, and fewer are born in the first quarter of the moon. The differences between the distribution observed during the lunar month and the theoretical distribution are statistically significant.
