Background Group housing of sows has been extensively studied since the EU banned gestation crating. Well-managed group-housing promotes sow welfare, but the impact varies based on factors such as feeding, group characteristics, and environmental features. Adequate floor space, particularly directly post-mixing, is crucial for social interactions, natural behaviours, and to reduce injuries caused by aggression. The aim of this study was to compare two group-housing systems for gestating sows with respect to productivity, treatment frequency, and removal of sows. Both systems were static but differed in space allowance, quantity of enrichment material and feeding management. System I comprised of large sized pens with deep litter straw bedding, housing in total 40 sows, and System II of smaller sized pens with permanent access to straw, housing 8 to 10 sows. Results The mean parity number was 3.1 ± 1.3 in both groups. Sows housed in System I with large groups ( n  = 40) in large pens with deep litter straw gave birth to 16.8 ± 0.33 (Least Squares Means, LSM) piglets, compared to 15.4 ± 0.31 (LSM) for sows in System II kept in smaller groups ( n  = 8–10) in smaller pens ( p  = 0.0005). Medical treatments of sows were more frequent ( p  < 0.001) in System II. The incidence of replacement of sows was comparable in both systems, and there was a high occurrence of sows becoming pregnant during the subsequent insemination in both groups. Conclusions This study indicated that sows kept in larger groups provided with a larger floor space (a total area of 156 m 2 , corresponding to 3.9 m 2 per sow) and housed on deep straw had a higher number of liveborn and weaned piglets and lower incidence of antibiotic treatments than sows with less floor space (a total area of 24.5 m 2 , corresponding to 2.5–3.1 m 2 per sow) and less bedding/manipulable material.

La môle hydatiforme partielle (MHP) fait partie des maladies trophoblastiques gestationnelles. Appelée également môle embryonnée, il s’agit d’un œuf humain pathologique comportant des villosités en transformation vésiculaire, mais conservant une forme placentaire reconnaissable et une cavité amniotique avec un fœtus. La circonstance diagnostique la plus commune étant le tableau d’avortement spontané au premier trimestre. Rarement les môles partielles persistent au-delà du premier trimestre et sont alors source de complications maternelles et fœtales et de confusion diagnostique. L’origine génétique des MHP correspond à une conception triploïde avec un lot chromosomique supplémentaire d’origine paternelle. La coexistence d’un fœtus de caryotype normal avec une MHP est une situation exceptionnelle. Nous rapportons un cas rare de grossesse molaire partielle avec fœtus vivant diploïde à 27 semaines d’aménorrhée (SA) chez une femme âgée de 36 ans dont le diagnostic est porté à l’occasion d’une menace d’accouchement prématurée associée à un placenta prævia.

Les données d’enquêtes recueillies sur la survie des frères et sœurs constituent une source incontournable pour estimer la mortalité des adultes dans les pays où l’état civil reste incomplet. Cet article évalue la qualité de ces données en comparant la taille des fratries déclarées dans les enquêtes démographiques et de santé avec le nombre moyen d’enfants nés vivants des femmes de la génération précédente. Cette comparaison, menée au niveau agrégé, suggère qu’une proportion élevée de frères et sœurs sont omis ; les tailles de fratries sont inférieures de 15 % environ aux tailles attendues sur la base des enfants nés vivants. Ces omissions sont plus fréquentes en Afrique subsaharienne que dans les autres régions en développement et leur ampleur augmente légèrement avec l’âge des enquêtées. La mortalité aux âges adultes déduite de ces données n’est pas pour autant sous-estimée, car les omissions semblent surtout concerner des frères et sœurs décédés dans l’enfance. Sibship sizes and family sizes in survey data used to estimate mortalitySurvey data on sibling survival provide a crucial source of information for estimating adult mortality in countries where vital records are incomplete. This article assesses the quality of these data by comparing sibship sizes reported in Demographic and Health Surveys with women’s mean number of children ever born in the previous generation. This comparison, conducted at aggregate level, suggests that a high proportion of siblings are omitted, since the sibship sizes are 15 % lower, on average, than would be expected on the basis of number of children ever born. Such omissions are more frequent in sub-Saharan Africa than in other developing regions, and their extent increases slightly with the respondents’ age. Adult mortality deduced from these data is not necessarily underestimated, however, since omissions appear to mainly concern siblings who died in childhood.

Objectives: To describe the aetiology and short-term outcome of live-born infants with non-immune hydrops fetalis (NIH), to identify predictors of mortality and to establish whether there has been any change in mortality over a 14-year period. Methods: A retrospective case note review of all liveborn neonates with NIH. Results: 30 infants were identified. Twenty (66%) had an identifiable aetiology. Ten (33%) survived to discharge. Survivors had significantly higher Apgar scores at 1 and 5 min (both p < 0.001). Mortality did not differ between the time periods 1990–1999 and 2000–2004. Conclusions: NIH continues to be associated with a significant mortality despite advances in perinatal care. Poor condition at birth is a strong predictor of death.
