Full textNoninvasive determination of aortic stiffness has sparked considerable interest over the last four decades. Actually, increased aortic stiffness has emerged as an independent predictor of cardiovascular events and mortality, and as the main responsible of isolated systolic hypertension. However, the impacts of aortic stiffness on microcirculation and organ damages are best explained through the arterial stiffness gradient, in other words, with the interaction between soft aorta and adjacent stiff muscular arteries. Mechanical properties of muscular mid-caliber arteries (ex: brachial artery) are thought to be relatively stable over time, and then, do not significantly contribute to the lost and inversion of the arterial stiffness gradient with aging. In a longitudinal study with hemodialysis patients, we observed an annual decrease in brachial stiffness despite an accelerated increase in aortic stiffness. These observations let us hypothesize, first, that muscular arteries may not be as stable over time as it is expected and second, that arterial stiffness gradient may be a better predictor of mortality as both peripheral and central stiffness may change, at least in a high-risk population. The objectives of this thesis were to assess the combined effect of a reduced brachial stiffness and increased aortic stiffness on all-cause mortality by proposing a parameter of arterial stiffness gradient, the aortic-brachial PWV ratio (PWV ratio: cf-PWV/cr-PWV), to examine relationships between hemodynamic parameters, PWV ratio and its two PWV components, and to assess determinants of changes in brachial stiffness. In a dialysis cohort of patients, we demonstrated that PWV ratio was an independent predictor of all-cause mortality that performed better than aortic stiffness and other hemodynamic parameters. In contrast with aortic stiffness which is dependent on operational pressure, we demonstrated in a second study the pressure independence of PWV ratio in two different cohorts of patients. These results suggest that PWV ratio could be a new parameter of vascular aging with clinical interest above and beyond aortic stiffness. This study also a general regression of brachial stiffness in dialysis patients and over the sixth decade of age in the other cohort of patients. The regression of brachial stiffness, as presented in the first study of this thesis, was not explained by age, traditional risk factors, and mineral parameters. Baseline aortic stiffness was the only determinant of the decrease in brachial stiffness, which let us propose that muscular arteries may adapt to high aortic stiffness by becoming more compliant, dampening the ejected blood volume from the ventricular contraction instead of the aorta. This thesis also presents our last study on a new method of pulse wave analysis, the reservoir-wave approach, which reintroduces the importance of peripheral resistance and arterial compliance (reservoir pressure) in the comprehension of pressure curves. We observed that brachial stiffness was significantly associated with the reservoir pressure, but also with diastolic pressure. Finally, works presented in this thesis were conducted with the participation of chronic kidney disease patients, a very interesting population characterized by an early and accelerated vascular aging. Consequently, our results may not be reproducible in healthy or lower-risk populations.

Full textVascular disease is one of the most common diseases that occurs among the population. Two of the arteries, which mainly supply the arms with blood, is called subclavian artery and brachial artery. Today, there are no reference values for the subclavian artery and the brachial artery. This makes it more difficult to examine these vessels and answer questions that concern them. Ultrasound is a suitable method in order to observe conditions in these vessels, since the ultrasound is both non-invasive and cost-effective and the method do not give the patient any discomfort or expose them to radiation. The purpose of this study was to obtain reference values for subclavian artery and brachial artery plexus, which can be used in different vessel examinations at the department. In order to develop the reference values of the diameter, the volume flow rate and the blood flow velocity of subclavian artery and brachial artery, an ultrasound scan was carried out in 25 healthy participants, 8 males and 17 females. Reference values for the left and right diameters of the brachial artery were between 3.1-3.5 mm and 3.2-3.6 mm. The volume flow in the left and right brachial artery was between 0.029-0.042 L/min and 0.035-0.049 L/min. The blood flow velocity in the left and right brachial artery was between 0.818-0.968 m/s and 0.881-0.946 m/s. The diameter in the left and right subclavian was between 4.7-5.4 mm and 4.8-5.5 mm. The volume flow in the left and right subclavian, was between 0.087-0.124 L/min and 0.096-0.119 L/min. The blood flow velocity in the left and right subclavian was between 0.948-1.106 m/s and 0.909-1.118 m/s. Parameters that had significant correlation with age in this study were blood flow velocity and volume flow in the right brachial artery and the diameter of the left and right subclavian artery. Based on this study, no clear conclusions can be drawn as to which reference values should be used in the clinical practice. This is due to a low number of participants and low age distribution.

Full textThe main aim of this study is to better state precisely the arterial vasomotor control mechanisms of the hand. This study is effected on healthy volunteers one part at basal state control experience and in the other part after separate administration of vasoactive drugs, and this for different temperatures of the hand: ambient air, ten, twenty, thirty and fourth degrees centigrade. The method used consisted in determination of humeral blood flow (diameter, velocity) with a pulsed ultrasound Doppler velocimeter. Simultaneous the indirect measurement of blood pressure permitted to calculate loco-regional vascular resistances. In ambient air, the vascular resistances of the upper limb are significantly modified in comparison with control experience only with prazosin (eight per cent lowered) and in least measure with nifedipin (four percent lowered). The biggest and the more significant modifications are obtained at twenty degrees temperature of the hand. Then the vascular resistances increased more than fifty per cent under beta blockers and they decreased from twenty per cent under prazosin and enalapril and more than fourth per cent under nifedipin. These results point out that in the case of the circulation of the upper limb, the alpha and beta adrenergic neural control and hormonal control by renin-angiotensin system are very present in physiological conditions at the cutaneous arterial level particularly in the hand, in contrast with muscular arterial level of fore-arm: This explains the great reactivity of the cutaneous arterial circulation of the hand to thermal stimulus which is firstly to the service of the whole body economy

Full textInterscalene brachial plexus block (ISB) in addition to general anesthesia is widely used in patients undergoing shoulder surgery to improve the regional pain therapy. The use of ultrasound for identifying the brachial plexus is a new method in comparison to the standardized procedure of nerve stimulation, allowing the direct visualization of the target and surrounding structures without the need of electric stimulation of nerves. In our prospective study including 500 patients we compared the methods “nerve stimulation”, “ultrasound” and “combination of both” in terms of execution, effectiveness, complications and patient satisfaction. While the execution time was comparable in both methods, the ultrasound guidance showed less pain and paresthesia during application of the ISB. The combination of both procedures took statistically longer and caused paresthesia most frequently. The success rate was higher in the group “nerve stimulation” than in the ultrasound-guided ISBs, whereas the discrepancy was not significant. There was no statistically relevant difference in the effectiveness of the interscalene plexus blocks as measured in postoperative pain intensity, drug class of first given pain relievers, stay in anesthetic recovery room and duration of nerve block. Only the time until the first application of pain killers was significantly longer with nerve stimulation. Considering the incidence of postblock neurological or respiratory complications and the patients satisfaction there were no differences between the methods of performing the ISBs. The most important advantage of ultrasound-guidance is the direct visualization of anatomical structures as well as the injection of the local anesthetic and therefore the possibility to avoid major complications. With omission of electric nerve stimulation patient comfort is higher. Our results prove that ultrasound-guided performance of ISBs is an alternative to nerve stimulation

Full textIn this prospective, controlled double-blind study, prilocaine 1 %, a short-to-medium time acting local anaesthetic, was combined with ropivacaine 0.5 % or Bupivacaine 0.5%, both long time acting local anaesthetics, to find a new active profile. Therefore, 120 patients scheduled for axillary block for elective upper limb surgery were randomly assigned to four groups: 30 patients of each group received either 7 mg/kg prilocaine 1 % (group P), 7 mg/kg prilocaine 1 % + 0.75 mg/kg ropivacaine 0.5 % (group PR), 7 mg/kg prilocaine 1 % + 0.75 mg/kg bupivacaine 0.5 % (group PB) or 3 mg/kg ropivacaine 0.5 % (group R), respectively. The axillary plexus was identified with a nerve stimulator and the local anaesthetics were injected into the perivascular sheath. The main outcome measures were onset time to anaesthesia (every 5 min) and postoperative analgesic duration of sensory and motor block for the median, radial and ulnar nerve(every 15 min). Additionally, return of pain and postoperative analgesic requirements were recorded. Intensity of pain was postoperative determined every 30 min by a verbal rating scale. Analgesia was classified using the pin-prick method, motor block was analysed by the knowledge of the specific segment-indicating muscles. Median duration of sensory and motor block was significantly increased in group R compared to group P, PR and PB (p < 0.001). In contrast, analgesia was significantly decreased in group P compared to group R, PR and PB (p < 0.001). No significant differences of all tested parameters between group PR and PB could be observed. To compare postoperative pain and analgesic requirements, the number of patients, who received postoperative analgesics, didn’t change significantly between the groups, nevertheless there was significance between group R and PB concerning time until administration of analgesic (p < 0.009). A mixture of prilocaine 1 % with ropivacaine 0.5 % or bupivacaine 0.5 %, respectively, prolonged the duration of sensory and motor block without modifying the onset time. In view of the higher cardiotoxic potency of bupivacaine compared to ropivacaine the local anaesthetic mixture prilocaine 1 % with ropivacaine 0.5 % should be preferred

Full textLes infiltrations foraminales cervicales sont associées à un risque de complications neurologiques majeures. Cette étude compare l’efficacité des infiltrations facettaires, plus sécuritaires, à celle des infiltrations foraminales dans le traitement de la cervico-brachialgie secondaire à une spondylose et/ou à une hernie discale, à 4 semaines post traitement. Cinquante-six sujets ont été randomisés pour recevoir une infiltration foraminale (15 hommes, 13 femmes ; âge moyen 52 ans) ou facettaire (8 hommes, 20 femmes ; âge moyen 44 ans). L’issue principale était l’intensité de la douleur mesurée sur une échelle visuelle analogique (0 – 100). Les issues secondaires étaient le Neck Disability Index et le Medication Quantitative Scale. Suivant les analyses en intention-de-traiter et en intention-du-protocole, pour un score de douleur initial moyen, une réduction significative de l’intensité de la douleur a été observée avec les infiltrations facettaires [45.3% (95%CI: 21.4; 69.2) et 37.0% (95%CI: 9.2; 64.7)] contrairement aux infiltrations foraminales [9.8% (95%CI: +11.5; 31.2) et 17.8% (95%CI: +6.6; 42.2)]. Les infiltrations facettaires ont procuré une amélioration cliniquement (mais non statistiquement) significative du Neck Disability Index [24.3% (95%CI: +2.9; 51.5) et 20.7% (95%CI: +6.2; 47.6),], contrairement aux infiltrations foraminales [9.6% (95%CI: +15.2; 34.4) et 12.8% (95%CI: +11.2; 36.7)]. Les infiltrations facettaires étaient au moins aussi efficaces que les infiltrations foraminales pour un score initial de douleur ≤ 60, alors que l’analyse de non infériorité n’était pas concluante pour un score initial ≥ 80, de même que pour le Neck Disability Index. Les infiltrations n’ont pas été associées à une réduction du score de Medication Quantitative Scale. Les infiltrations facettaires sont efficaces dans le traitement de la névralgie cervico-brachiale et représentent une alternative valable et plus sécuritaire aux infiltrations foraminales.
Transforaminal corticosteroid injections can be performed in the management of cervical radiculopathy but carry the risk of catastrophic complications. This study compares the efficacy of transforaminal and facet corticosteroid injections at 4 weeks post treatment. We randomly assigned 56 subjects to receive CT-guided transforaminal (15 men, 13 women; mean age 52 years; range 28 – 72 years) or facet (8 men, 20 women; mean 44 years; range 26 – 60 years) injections. The primary outcome was pain severity rated on a visual analog scale (0-100). Secondary outcome measures were the Neck Disability Index and the Medication Quantitative Scale. In the intention-to-treat and as-treated analyses, for a mean baseline score, facet injections demonstrated a significant pain score reduction of 45.3% (95%CI: 21.4; 69.2) and 37.0% (95%CI: 9.2; 64.7), while transforaminal injections showed nonsignificant pain score reduction of 9.8% (95%CI: +11.5; 31.2) and 17.8% (95%CI: +6.6; 42.2). While facet injections demonstrated an improvement in Neck Disability Index score of [24.3% (95%CI: +2.9; 51.5); 20.7% (95%CI: +6.2; 47.6),] as opposed to transforaminal injections [9.6% (95%CI: +15.2; 34.4); 12.8% (95%CI: +11.2; 36.7)], the results did not reach statistical significance. Noninferiority of facet to transforaminal injections was demonstrated for baseline pain score ≤ 60, while noninferiority analysis was inconclusive for baseline pain score ≥ 80 and for the Neck Disability Index score. Neither intervention showed a significant medication intake score reduction over time. Facet injections are effective for the treatment of cervical radiculopathy and represent a valid and safer alternative to transforaminal injections.

Full textTreatment of brachial plexus lesions is attempted by surgical replantation of avulsed nerve roots. Prerequisites for successful regeneration of motoneuron axons are 1. survival of a large number of motoneurons, 2. restoration of connectivity between avulsed nerve roots and spinal cord and 3. high quality of regenerated axons. Regeneration and survival of motoneurons can be supported by neurotrophic factors. In the present study, the influence of CNTF and BDNF on regeneration of motoneurons after C7 ventral root avulsion and replantation after 3 weeks and 6 months was analysed. Additionally, detailed morphological analyses of dorsal root ganglia (DRG), severed dorsal roots and injured dorsal horns were performed. In adult rabbits C7 dorsal roots were severed, ventral roots were avulsed and replanted ventrolaterally. CNTF, BDNF, or both was applied to the replantation site, controls were replanted without application of neurotrophic factors (n>5). After 3 weeks (n= 3 controls) and 6 months (n= 27) after avulsion and replantation semi-thin sections of ventral roots and DRGs as well as cryostat serial sections from C7 spinal cord segment were prepared. DiI-fluorescence tracing, myelin-sheath staining, modified Klüver-Barrera staining of cryostat section and touloidinblue staining of semi-thin sections served for morphological and quantitative analyses. Six months after lesion, a survival of 30% of the C7 motoneurons was found without differences between the experimental groups. Retrograde fluorescent tracing and histological analysis documented that many axons had regrown through the original ventral exit zones or had exited the spinal cord at the lateral replantation site. However, many laterally exiting axons had not grown out directly from the ventral horn through the lateral white matter but had elongated vertically before leaving the spinal cord. The mean axonal diameter was significantly higher in regenerated axons that had exited through the original ventral exit zones in comparison with axons which had grown out laterally. Application of BDNF and/or CNTF did not show any effects on the pathways of regeneration into the replanted root. Three weeks after ventral root avulsion and replantation the number of axons was rare. After six months, the number of myelinated axons increased to 45% compared to unlesioned sides. Regenerated axons were mainly of small caliber with few axons showing typical properties of motoneuron axons. In controls myelination was significantly reduced compared to the unlesioned sides. This was not observed after CNTF, BDNF and CNTF+BDNF treatment. In CNTF+BDNF treated animals myelination was significantly increased compared to replanted controls in the majority of cases. At the dorsal root entry zone, small myelinated axons extended into central tissue protrusions, in cases with well-preserved morphology. This suggested sprouting of spinal neuron processes into the central dorsal root remnant. In lesioned DRGs, the density of neurons and myelinated axons was not significantly altered, but a slight decrease in the relative frequency of large neurons and an increase of small myelinated axons was noted (significant for axons). Unexpectedly, differences in the degree of these changes were found between control and neurotrophic factor-treated animals. Central axons of DRG neurons formed dorsal root stumps of considerable length which were attached to fibrous tissue surrounding the replanted ventral root. In cases where gaps were apparent in dorsal root sheaths, a subgroup of dorsal root axons entered this fibrous tissue. Continuity of sensory axons with the spinal cord was never observed. Some axons coursed ventrally in the direction of the spinal nerve. In summary, the number of surviving motoneurons and regenerating axons appeared not to be influenced by a single- dose application of neurotrophic factors in this model. However, improvement of myelination indicated that the quality of regeneration can be increased especially by CNTF+BDNF- treatment. Moreover, the considerable capacity of dorsal root regeneration we observed in this study has possibly been underestimated previously. The unexpected ingrowth of dorsal root axons into the regenerated ventral roots could be harmful for ventral root regeneration

Full textBackground The Westernization of lifestyles, notably dietary habits, seems to be largely responsible for the ongoing increase of incidence of cardiovascular diseases. The postprandial period, where vascular and metabolic homeostatic regulating processes are under pressure, is of considerable importance in the development or prevention of atherosclerosis and now represents the majority of waking hours. The understanding of the postprandial effects of meals of varying composition is therefore essential in our effort to prevent such diseases. Objectives The main objective of this research project was to study the endothelial and metabolic responses to a mixed Mediterranean meal (MMM), since they are unknown. This project also aimed to evaluate the microvascular impact of such a meal and to characterize the composition of postprandial plasma fatty acids. These elements were also evaluated following a saturated fatty meal (HSFAM) for comparison. Methods Twenty-eight (28) healthy men free of cardiovascular diseases and risk factors were randomly assigned one of two test meals. The MMM, consisting of fresh salmon and vegetables cooked in olive oil, contained 7.87g of SFA and 2.29g of omega- 3 fatty acids, while the HSFAM, consisting of a breakfast sandwich with egg, sausage and cheese contained 14.78g of SFA. Evaluations of endothelial function by brachial ultrasound (FMD), of microvascular function by near-infrared spectroscopy (NIRS) and of plasma fatty acids composition were done in the fasted and postprandial states. Results Two subgroups of responders to the test meals emerged from this work. A first subgroup of subjects with high-normal fasting triglyceridemia (hnTG) experienced impairments of endothelial function following the HSFAM while a second subgroup of subjects with low-normal triglyceridemia (lnTG) did not experience any endothelial alterations following this meal. Interestingly, the MMM had no deleterious endothelial impact in any of those subgroups. Moreover, the hnTG subjects demonstrated greater postprandial triglyceridemic load (iAUC) that was in addition enriched with stearic acid after HSFAM and omega-3 PUFA following the MMM. Assessment of microvascular function revealed postprandial prolongation of post-ischemic reoxygenation only in hnTG subjects suggestive of alterations of capillary recruitment. These changes, which seemed to be more important after the HSFAM, could be partly responsible for its negative impact on FMD. Conclusions This clinical trial demonstrates in innovative ways that a MMM has no deleterious effects on endothelial function irrespective of triglyceridemia in normal ranges. In addition, high but normal fasting triglyceride levels suggest metabolic and endothelial dysfunctions following nutritional challenges such as a HSFAM. Consumption of Mediterranean meals by healthy individuals with marginal triglyceride levels would be beneficial, perhaps even more so than for individuals with lower triglyceride levels, in preventing atherogenesis and cardiovascular diseases.
