Identifier précocement les individus exposés au risque de développer une hypertension artérielle dans le futur et appliquer des mesures préventives dès le plus jeune âge devraient constituer une alternative au traitement pharmacologique de l'hypertension artérielle permanente chez l'adulte. L'exploitation d'une étude épidémiologique prospective conduite dans la Province de Liège a permis d'établir des valeurs de référence de la pression artérielle des adolescents et de souligner les particularités de la distributon et des déterminants du niveau de pression artérielle entre 12 et 17 ans.

Spring, W. Archives Neerlandaises des Sciences Exactes et Naturelles (1901), 6(ii), 257-61; SciFinder (Chemical Abstracts Service: Columbus, OH); https://scifinder.cas.org (accessed July 8, 2010). No combination took place on subjecting an intimate mixture of 2 mols. of cupric oxide and 3 mols. of sulphur to a pressure of 10,000 atmospheres. Combination took place violently when the pressure on a mixture of 2 mols. of cuprous oxide and 3 mols. of sulphur rose to 8000 atmospheres; the pressure was increased gradually so that no heating by compression took place. Sulphur dioxide was formed and the residue consisted only of cuprous sulphide (2Cu2O + 3S = 2Cu2S + SO2). The ignition temperature of this mixture at the ordinary pressure is about 126°, and pressure to the extent of 8000 atmospheres has the effect of lowering this by more than 100°. The ignition temperature of the mixture of cupric oxide and sulphur could not be determined for the sulphur inflamed at 250°, but it must be higher than this. It would appear that the point of inflammation is a function of the pressure, and the experiments are being continued to ascertain if this is quite general.

Notre étude a été menée en province de Kirundo au nord du Burundi où 355 exploitants agricoles ont été enquêtés dans les communes de Bugabira, Busoni, Bwambarangwe, Gitobe, Kirundo, Ntega et Vumbi respectivement 50, 75, 30, 40, 55, 55 et 50 exploitants agricoles. Le nombre de ménages agricoles enquêtés était fonction de la pondération du nombre d’exploitants dans chaque commune. Cette enquête était complétée par une étude documentaire. Les résultats issus de l’analyse des données montrent que la taille moyenne des ménages est de 5,01. Parmi les exploitants agricoles enquêtés 54 % ont une superficie de 0,234 ha, 25 % ayant une superficie de 0,678 ha tandis que 21 % seulement possèdent une superficie de plus d’un hectare. L’amenuisement des terres a provoqué une intensification des terres allant jusqu’à 200 % sans technique de renouvèlement de la fertilité. Cette surexploitation des sols provoquant ainsi une infertilité et une forte érosion de ces derniers a engendré une diminution de la production agricole. La raréfaction croissante des terres a provoqué de nombreux conflits relatifs à la propriété, aux successions et aux limites des parcelles; elle a également entraîné un exode rural des jeunes vers les villes à cause du désœuvrement observé chez les exploitants agricoles ayant des ressources naturelles limitées, mais aussi des mariages précoces chez leurs enfants. Certains exploitants ont laissé de cultiver leurs champs à cause de leur improductivité. Un facteur particulièrement visible de la dégradation de l'environnement au niveau de cette province est le déboisement continu sans technique de protection des sols provoquant ainsi un changement climatique.

Pressure pain threshold (PPT) is defined as the minimum force applied which induces pain. This measure has proven to be commonly useful in evaluating tenderness symptom. Our aim was to study the intra-examiner reproducibility of PPT measurement, define cutoffs in normal groups, and compare these results with patients with fibromyalgia (FM). Fifty healthy females, 50 healthy males, and 20 patients with FM participated in the study. PPTs were assessed for 18 specific tender point sites by a dolorimeter. The intra-individual coefficient of variation determined by a test-retest PPT measurement procedure with 3-days interval reached, respectively, 17% and 13% in healthy females and males, versus 24% in patients with FM PPTs were significantly lower in healthy females than in healthy males (p < 0.01). Statistical analysis failed to show any differences between the dominant and nondominant side for both normal groups. PPTs were lower over all examined areas in patients with FM than those obtained in healthy females (p < 0.000). Lower cutoff levels were calculated from normal values for all specific tender point sites. On average, 14 tender point sites in patients with FM were under the established lower cutoffs. In conclusion, pressure pain sensitivity was influenced by the anatomical localization of tender point and gender differences. Lowest PPTs were localized in trapezius, occiput, anterior cervical, and second rib. The reduction of total tender point score in patients with FM averaged 60% comparatively with normal values. PPT reproducibility and discrimination between the two groups were optimal for the gluteal and knee sites.

BACKGROUND AND METHODS: We aimed to characterize the effects of an endotoxin insult (Escherichia coli 0127:B8) on the relationships between pulmonary vascular pressure and flow in intact dogs. To achieve this goal, multipoint plots of total pressure gradient, arterial pressure gradient, and venous pressure gradient vs. flow were generated by graded inflation of a right atrial balloon, which was used to vary flow. The partitioning of the total pressure decrease across the pulmonary vasculature (total pressure gradient = pulmonary arterial pressure-pulmonary artery occlusion pressure [PAOP]) into gradients across pulmonary arterial (arterial pressure gradient = pulmonary arterial pressure--effective capillary pressure) and pulmonary venous (venous pressure gradient = effective capillary pressure--PAOP) regions was assessed by a waveform mathematical analysis of the pulmonary arterial pressure profile during arterial occlusion, with computation of both PAOP and effective pulmonary capillary pressures. Slopes and extrapolated pressure intercepts from linear regression fits to the pulmonary vascular pressure/flow plots were determined in seven dogs after a 2-hr endotoxic infusion interval and were compared with the corresponding values that characterized a similar group of sham-operated dogs. RESULTS: Under normal conditions, the extrapolated pressure intercept for pulmonary arterial pressure gradient was virtually 0 mm Hg; for total pulmonary arterial pressure gradient and pulmonary venous pressure gradient, the mean extrapolated pressure intercepts were substantially positive: 2.4 +/- 0.2 and 2.1 +/- 0.3 mm Hg, respectively. Endotoxin infusion at 0.25 micrograms/kg/min significantly increased the pressure intercepts from 2.4 to 8.7 and from 2.1 to 8.3 mm Hg of total pressure gradient and venous pressure gradient vs. flow, respectively. This infusion produced a minor, nonsignificant change in the intercept of arterial pressure gradient vs. flow, whereas it increased its slope significantly (p less than .05) from 0.036 to 0.081 mm Hg/mL/min/kg. CONCLUSIONS: These data suggest that endotoxin's effects on vascular resistance are exerted at two different loci such that these effects are additive. These endotoxin-induced effects consisted of increased vascular resistance of the arterial segment and appearance of a Starling resistor at the venous side of the pulmonary circulation, which acted as the relevant back-pressure to flow.

The paper studies the structural response of a beam subjected to a close-field local internal blast loading. In the literature, the pressure-impulse (p-I) diagram is commonly used to design elements or structures for a given blast loading. The p-I diagram is a spectrum representing the level sets of damage or required ductility for a given structural system, nonlinear beam in this paper. This representation is much appreciated because a simple reading for the actual pressure p and impulse I of the considered load indicates the ductility demand of the structural system. Recent works of quasi-static behaviour have indicated the crucial need to account for the membrane effects taking place in the extreme loading of frame beams. This paper will thus extend the state-of-art features, establishing thus the p-I diagram for a beam including the lateral restraints offered by the rest of the structure, the development of non-linear membrane action and also, the M-N interaction that develops in the plastic hinges.

The effects of octreotide pretreatment before surgery were assessed in 48 acromegalic patients who underwent trans-sphenoidal surgery to remove pituitary adenoma, and compared with 107 patients who did not receive octreotide before surgery. Pretreated patients received octreotide 100 micrograms, thrice daily for 3 to 6 weeks (group 1), or 100 to 500 micrograms, thrice daily for 3 to 39 months (group 2). Total remission of symptoms was seen in 54%. Partial remission of symptoms occurred in 39%. Octreotide pretreatment reduced plasma GH levels by > or = 50% in all patients. GH levels were reduced to < 2 micrograms/1 in 3/14 group 1 cases and 13/34 group 2 cases. Tumour shrinkage occurred in 56.5% of patients. Marked tumour shrinkage (> 25%) occurred in more group 2 patients (10/32 vs 1/14). The tumour was soft in 39 patients, firm in 6 and hard in 3 cases. Soft consistency aided surgical removal of adenomas. Remission was greater in enclosed adenomas than in invasive tumours in both octreotide pretreated and nonpretreated acromegalics (76 vs 30%). Remission was more likely if the adenoma was less than 16 mm. Remission rate was significantly greater (p < 0.05) in all octreotide pretreated than in untreated patients for enclosed adenoma, but not for invasive adenoma. Octretide pretreatment can be recommended for three to four months prior to surgery. [less ▲]
