2005, Nammour, S.; Rocca, J.-P.; Keiani, K.; BALESTRA, Costantino
; Snoeck, T.; Powell, L.; Van Reck, J., HE Bruxelles Brabant
Article scientifiqueOBJECTIVE: The purpose of this study was to define the optimal irradiation conditions of a KTP laser during root planing treatment. METHODS: The surfaces of 60 single-root human teeth were scaled with conventional instruments before lasing. The pulpal temperature increase was measured by means of one thermocouple placed in the pulp chamber and a second one placed on the root surface at 1 mm from the ... -

Article scientifiquehas been advocated for a long time. Several beneficial effects of NBO have been demonstrated, one of which is the faster elimination of tissue nitrogen bubbles. During DCS occurrence, a cascade of intravascular reactions has been demonstrated. These inflammatory reactions occur within minutes of the onset of DCS, and involve the precipitation of proteins on the gas-bubble interface, causing a ... -
The fractal approach as a tool to understand asymptomatic brain hyperintense MRI signals
2004, BALESTRA, Costantino; Marroni, A.; Farkas, B.; Peetrons, P.; Vanderschueren, F.; Duboc, E.; ; , HE Bruxelles Brabant
Article scientifiqueThe prevalence of a Patent Foramen Ovale is described in merely 30% of the asymptomatic population. This patency has been shown to be an increasing risk factor for paradoxical cerebral embolization. Some desaturation or decompression situations in human activities such as scuba diving or altitude flight are prone to provoke embolisations. The association with the presence of a patent Foramen Ovale ... -
Evidence for increasing patency of the foramen ovale in divers
2005, ; Hastir, F.; Dendale, P.; Marroni, A.; Nguyen, A.-F.; BALESTRA, Costantino, HE Bruxelles Brabant
Article scientifiquesing a standardized contrast-enhanced transesophageal echocardiographic technique, a group of divers was reexamined for the presence and size of patent foramen ovale (PFO) 7 years after their initial examinations. Unexpected but significant increases in the prevalence and size of PFO were found, suggesting a possible increasing risk for decompression sickness in these divers over time. -
A deep stop during decompression from 82 fsw (25 m) significantly reduces bubbles and fast tissue gas tensions.
janvier 2004, Marroni A; Bennett PB; Cronje FJ; Cali-Corleo R; ; Pieri M; Bonuccelli C; BALESTRA, Costantino, HE Bruxelles Brabant
Article scientifiquen spite of many modifications to decompression algorithms, the incidence of decompression sickness (DCS) in scuba divers has changed very little. The success of stage, compared to linear ascents, is well described yet theoretical changes in decompression ratios have diminished the importance of fast tissue gas tensions as critical for bubble generation. The most serious signs and symptoms of DCS ... -
Erythropoietin production can be enhanced by normobaric oxygen breathing in healthy humans
2004, BALESTRA, Costantino; ; Poortmans, J.; Marroni, A.; Schiettecatte, J.; Collard, J.-F.; , HE Bruxelles Brabant
Article scientifiqueErythropoietin (EPO) induces red blood cell production by activating red bone marrow progenitor cells, and is used therapeutically in chronic anemia. It is also used as an unauthorized adjunct to increase the oxygen transport capacity in the blood of athletes. Renal tissue hypoxia is the only widely accepted trigger for EPO production (1-3), even if new oxygen-sensitive sites have been recently ... -
Scuba diving can induce stress of the temporomandibular joint leading to headache [1]
Article scientifiqueIn ordinary recreational scuba diving, many anatomical parts can be involved in disorders of cranial regions: ears and eyes are involved but also sinuses. Dental problems are generally involved in barotraumas because of bad dental fillings or other matters of interest to the general dental practitioner.1 Very few papers have looked at the articular and periarticular problems of the temporomandibular joint ... -
Hand-Arm Bimanual Intensive Therapy Including Lower Extremities (HABIT-ILE), cadre de pratique et effets de la thérapie : une revue de la portée
2022, HE Léonard de VinciHE Louvain en HainautArticle scientifiqueContexte. HABIT-ILE, « Hand-Arm Bimanual Intensive Therapy Including Lower Extremities », est une des thérapies recommandées pour améliorer la fonction de l’enfant avec une paralysie cérébrale unilatérale (UCP) et bilatérale (BCP). S’agissant d’une intervention récente, ses effets et son cadre de pratique n’ont pas encore fait l’objet d’une revue de la littérature. C’est l’objectif de ce travail. ... -
Intensive upper- and lower-extremity training for children with bilateral cerebral palsy: a quasi-randomized trial
2017, HE Léonard de VinciArticle scientifiqueAn approach that simultaneously engages both the upper and lower extremities, hand–arm bimanual intensive therapy including lower extremity (HABIT-ILE), has recently demonstrated improvements in upper and lower extremities in children with unilateral cerebral palsy (CP). It is not known whether children with bilateral CP would benefit from this approach. The aim of this study was to examine the ... -
ACTIVLIM-CP a new Rasch-built measure of global activityperformance for children with cerebral palsy
2016, HE Léonard de VinciHE Louvain en HainautArticle scientifiqueObjective Children with cerebral palsy (CP) often have upper extremity (UE) and lower extremity (LE) impairments. While tools measuring separately UE and LE abilities are currently used, activities in which UE and LE are used in combination – numerous in everyday life – cannot be assessed because no instrument allows capturing global activity performance in children with CP. This study aimed to ... -
Brain activation changes following motor training in children with unilateral cerebral palsy: An fMRI study
2021, HE Léonard de VinciArticle scientifiqueBACKGROUND: Intensive motor-learning-based interventions have demonstrated efficacy for improving motor function in children with unilateral spastic cerebral palsy (USCP). Although this improvement has been associated mainly with neuroplastic changes in the primary sensori-motor cortices, this plasticity may also involve a wider fronto-parietal network for motor learning. OBJECTIVE: To determine ... -
Patent foramen ovale and decompression sickness in sports divers.
Article scientifiquePatency of the foramen ovale (PFO) may be a cause of unexplained decompression sickness (DCS) in sports divers. To assess the relationship between PFO and DCS, a case-control study was undertaken in a population of Belgian sports divers. Thirty-seven divers who suffered from neurological DCS were compared with matched control divers who never had DCS. All divers were investigated with transesophageal ... -
Effects of fatigue on the stretch reflex in a human muscle
Article scientifiqueThe effects of fatigue on the electromyographic (EMG) reflex activities were compared during sustained voluntary contractions and contractions evoked by electrical stimulation (30 Hz) in the human first dorsal interosseus (FDI). Short latency (SL), medium latency (ML) and long latency (LL) reflex responses to a ramp-and-hold stretch of the muscle were recorded and analysed in 27 healthy subjects of ... -
Reflex regulation during sustained and intermittent submaximal contractions in humans
Article scientifiqueTo investigate whether the intensity and duration of a sustained contraction influences reflex regulation, we compared sustained fatiguing contractions at 25 % and 50 % of maximal voluntary contraction (MVC) force in the human abductor pollicis brevis (APB) muscle. Because the activation of motoneurones during fatigue may be reflexively controlled by the metabolic status of the muscle, we also ... -
Intrathoracic pressure changes after Valsalva strain and other maneuvers: Implications for divers with patent foramen ovale
Article scientifiqueScuba divers with patent foramen ovale (PFO) may be at risk for paradoxical nitrogen gas emboli when performing maneuvers that cause a rebound blood loading to the right atrium. We measured the rise and fall in intrathoracic pressure (ITP) during various maneuvers in 15 divers. The tests were standard isometric exercises (control), forceful coughing, knee bend (with and without respiration blocked), ... -
Prendre soin en temps de crise : une opportunité pour refonder les liens. Réflexion à deux voix
24 juin 2024, HE Léonard de VinciArticle scientifiqueLa pandémie causée par la Covid-19 a constitué un contexte de crise sans précédent. Dans le monde soignant, elle a notamment accentué les limites d’une logique privilégiant les décisions appuyées sur une visée gestionnaire et comptable. Elle a également visibilisé les difficultés auxquelles sont confrontés les soignants lorsqu’ils recourent à la logique du prendre soin (care). Considérant la crise ... -
