A case-control study about foetal trauma during caesarean delivery.

Objective: The caesarean section rate is gradually increasing in most countries. The frequency of occurrence of foetal injury per birth is estimated to 1%. The majority of these injuries presents a low functional impact, but remains responsible for a significant neonatal morbidity.

Heart rate variability in the standing position reflects training adaptation in professional soccer players.

Purpose: To show that heart rate variability (HRV) in the standing position better reflects the way in which athletes adapt to training in so-called intermittent sports than the indicator of resting parasympathetic tone usually employed in endurance sports.

Methods: Twenty professional soccer players (intermittent sport) took part in a 5-week training session divided into three successive periods: "Warm-up", "Intensive training" and "Tapering". At the beginning and end of each of the three periods, a stand test was carried out and the heart rate was recorded, beat by beat (Polar Team 2).

Constitutive mosaic aneuploidy is a unique genetic feature widespread in the Leishmania genus.

Using fluorescence in situ hybridization, we determined the ploidy of four species of Leishmania: Leishmania infantum, Leishmania donovani, Leishmania tropica and Leishmania amazonensis. We found that each cell in a strain possesses a combination of mono-, di- and trisomies for all chromosomes; ploidy patterns were different among all strains/species. These results extend those we previously described in Leishmania major, demonstrating that mosaic aneuploidy is a genetic feature widespread to the Leishmania genus.

Active epidemiological surveillance of musculoskeletal disorders in a shoe factory.

Aims: (1) To evaluate an active method of surveillance of musculoskeletal disorders (MSDs). (2) To compare different criteria for deciding whether or not a work situation could be considered at high risk of MSDs in a large, modern shoe factory.

Methods: A total of 253 blue collar workers were interviewed and examined by the same physician in 1996; 191 of them were re-examined in 1997.
