État de stress post-traumatique chez les mères et chez les pères d'enfants prématurés: similitudes et différences = Prematurity and parental post-traumatic stress disorder: similarities and differences

Objectifs Évaluer et comparer la présence de symptômes de stress post-traumatique, en fonction de la gravité de la prématurité, chez les mères et chez les pères de bébés nés prématurément. Méthode En fonction du score de risque périnatal (PERI) du bébé, les parents des prématurés (âge gestationnel moins de 34 semaines) ont été divisés en deux groupes : les parents de prématurés à faible risque (n = 16) et à haut risque (n = 26). Les symptômes d'intrusion et d'évitement, de l'état de stress post-traumatique, ont été évalués chez les parents à l'aide d'un questionnaire, l'Impact of Event Scale (IES). Leurs réponses ont été comparées à un groupe témoin de parents de nouveau-nés à terme (n = 24). Les différences entre les réponses des mères et des pères, ont été analysées. Résultats Les parents de bébés prématurés sont plus à risque que les parents de nouveau-nés à terme de présenter des symptômes de stress post-traumatique. Les mères en lien avec le fait même de la prématurité du bébé, les pères en lien avec la gravité de la prématurité. Les mères et les pères des prématurés des deux groupes (prématurés à faible risque, prématurés à haut risque) décrivent des symptômes d'intrusion, alors que les symptômes d'évitement sont décrits par toutes les mères, mais seulement par les pères de prématurés à haut risque périnatal. Conclusion La naissance prématurée est susceptible d'entraîner l'apparition de symptômes de stress post-traumatique chez les parents. Les mères et les pères réagissent différemment. Objectives Evaluation of the symptoms of parental post-traumatic stress disorder (PTSD), according to the severity of the prematurity, in mothers and fathers of premature babies. Materials and methods According to the Perinatal Risk Inventory (PERI), the parents of premature infants (gestational age less than 34 weeks) were divided into two groups, parents of a low-risk premature infants (n = 16) and of high-risk premature infants (n = 26). The symptoms of intrusion and avoidance, as a part of the post-traumatic stress disorder, were evaluated by an autoadministrated questionnaire, the Impact of Event Scale (IES). Their responses were compared with a control group of parents of full-term infants (n = 24). The differences in the answers of mothers and fathers were analysed. Results The occurrence of symptoms of post-traumatic stress disorder is increased in parents of preterm infants compared with the control group. Whereas mothers of premature infants are at risk of presenting symptoms of PTSD, linked to the prematurity, with fathers the infant perinatal risk factors play a greater role. The symptoms of intrusion are present in mothers and fathers of preterm infants of both groups. Mothers of both groups present avoidance symptoms, although only fathers of high-risk preterm infants present them. Conclusions Premature birth has an impact on both parents in terms of post-traumatic stress reactions. However, mothers and fathers react in different ways according to the severity of the prematurity.

Does history of falling predict length of stay in post-acute geriatric rehabilitation?

Objectives:To investigate the associations between falls before hospital¦admission, falls during hospitalization, and length of stay in elderly¦people admitted to post-acute geriatric rehabilitation. Method: History¦of falling in the previous 12 months before admission was recorded¦among 249 older persons (mean age 82.3±7.4 years, 69.1% women)¦consecutively admitted to post-acute rehabilitation. Data on medical,¦functional and cognitive status were collected upon admission. Falls¦during hospitalization and length of stay were recorded at discharge.¦Results: Overall, 92 (40.4%) patients reported no fall in the 12 months¦before admission; 63(27.6%) reported 1 fall, and 73(32.0%) reported¦multiple falls. Previous falls occurrence (one or more falls) was significantly¦associated with in-stay falls (19.9% of previous fallers fell¦during the stay vs 7.6% in patients without history of falling, P=.01),¦and with a longer length of stay (22.4 ± 10.1 days vs 27.1 ± 14.3 days,¦P=.01). In multivariate robust regression controlling for gender, age,¦functional and cognitive status, history of falling remained significantly¦associated with longer rehabilitation stay (2.8 days more in single fallers,¦p=.05, and 3.3 days more in multiple fallers, p=.0.1, compared to¦non-fallers). Conclusion: History of falling in the 12 months prior to¦post acute geriatric rehabilitation is independently associated with a¦longer rehabilitation length of stay. Previous fallers have also an¦increased risk of falling during rehabilitation stay. This suggests that¦hospital fall prevention measures should particularly target these high¦riskpatients.

Validation of the post-delivery perceived stress inventory

This article presents the post-delivery perceived stress inventory (PDPSI) and its psychometric properties. This inventory is unique in that it links the measurement of perceived stress to events experienced during and after delivery. A total of 235 French-speaking, primiparous mothers completed the PDPSI two days after their delivery. To evaluate the predictive validity of the PDPSI on anxiety and depression, participants also completed the EPDS and the STAI two days and six weeks postpartum. The exploratory analysis revealed a 16-item structure divided into five factors: F1: relationship with the child; F2: delivery; F3: fatigue after delivery; F4: breastfeeding; and F5: relationship with the caregivers. The PDPSI demonstrated good internal consistency. Moreover, confirmatory factor analysis produced excellent indices, indicating that the complexity of the PDPSI was taken into account and its fit to the sample. The discriminant analysis showed that the PDPSI was not sensitive to specific changes in the sample making the inventory generalizable to other populations. Predictive validity showed that the scale significantly predicted depression and anxiety in the early postpartum period as well as anxiety six weeks postpartum. Overall, the PDPSI showed excellent psychometric qualities, making it a useful tool for future research-evaluating interventions related to perceived stress during the postpartum period.

Systematized stenting of Baerveldt shunts: techniques to reduce early post-operative hypotony

Purpose: To investigate the effect of the systematized use of intraluminal stents in Baerveldt shunts (BS) on early postoperative IOP control and complication rates. Methods: One hundred and twenty eyes with medically uncontrolled glaucoma were prospectively recruited to undergo BS implantation at Jules Gonin Eye Hospital, Switzerland. Baerveldt shunts were stented (full-length of the intraluminal tube) using a Supramid® 3.0 suture. A minority of shunts (37%) were also ligated intraoperatively and laser suture lysis performed postoperatively. Stent removals, either partial (retraction of 5mm) or complete, were carried out according to a predetermined protocol. Surgery was considered a success when IOP was ≤ 21mmHg and a minimum of 20% reduction from baseline was achieved with/without glaucoma medication (GMs). Hypotony related complications were defined as: choroidal effusions, shallow AC, hypotonous maculopathy or IOP≤5mmHg for over 2 weeks. Results: Mean age was 61.8 years (± standard deviation; ±21.5). Mean follow-up was 17.1 (±7.9) months. Mean preoperative IOP was 26.9 mmHg; mean IOP on the last visit 13.2 mmHg (p<0.001). At year one, the success rate was 87%. In 90% of eyes, IOP was ≤18 mmHg at last visit. Mean number of preoperatively GMs was 3.1; postoperatively 1.4 (p<0.001). Stent removals were performed in 87% of eyes (24% partial; 61% complete). 13% of eyes required no stent removal to reach target IOP. Complications were minor and infrequent (16%) and only 7% were hypotony related. Conclusions: Systematized use of intraluminal stents with Baerveldt aqueous shunts resulted in gradual and controlled IOP lowering with minimal hypotony-related complications. This may have important implications on clinical practice, given the rising rates of aqueous shunt implantation.

Chest pain and ST-segment elevation in a patient with Duchenne muscular dystrophy, what really happened?

Introduction: Myocardial infarction is rare in children, if it occurs, findings are almost similar to adults. In Ouchenne muscular dystrophy (OMO), ST segment displacement associated with typical chest pain can occur. We report the case of a young boy with OMO presenting symptoms suggestive of myocardial ischemia. Case report: 7 year old boy, diagnosed with OMO, eoming to the emergency department with complaints of acute chest pain, dyspnoea and anxiety the night before. Clinical examination was not remarkable, with exception of findings of the OMO. ECG showed important ST-segment elevation in right precordial leads. Major increase in troponin 1 42.33 mcg/(normal, <0.04 mcg/I) was found. Echocardiography revealed slight yskinesia of postero-septal wall without decrease in ventricular function. As acute pain had happened more han 12 hours before referral and as the child was asymptomatic, he received anti-platelets therapy. The serum level of troponin 1 declined and the ECG normalised in a few days. Cardiac catheterization did not show any coronary anomaly or eardiac dysfunction. Cardiac biopsy revealed myocardial cell damaged compatible with OMO cardiomyopathy. Tc99m myocardial single-photon emission computed tomography (SPECT) did not show any radionuclide uptake defect. Conclusions: ln this particular context of children with OMO, the classical signs of myocardial ischemia could be misleading, standard investigation failed to demonstrate the cause of chest pain and inerease of troponin l, there was also no evidence of myocarditis. Role of late enhancement (LE) signal in eontrast-enhanced MRI in the understanding of the occurring process has to be evaluated.

Revue critique d'instruments pour evaluer la douleur chez les personnes cérébrolésées non communicantes aux soins intensifs [Critical review of instruments to assess pain in the non communicative brain injured persons in intensive care].

The purpose of this review is to critically appraise the pain assessment tools for non communicative persons in intensive care available in the literature and to determine their relevance for those with brain injury. Nursing and medical electronic databases were searched to identify pain tools, with a description of psychometric proprieties, in English and French. Seven of the ten tools were considered relevant and systematically evaluated according to the criteria and the indicators in the following five areas: conceptualisation, target population, feasibility and clinical utility, reliability and validity. Results indicate a number of well designed pain tools, but additional work is necessary to establish their accuracy and adequacy for the brain injured non communicative person in intensive care. Recommendations are made to choose the best tool for clinical practice and for research.

Rôle de l'exercice dans l'approche multidisciplinaire de la lombalgie chronique

RÉSUMÉ L'exercice est utilisé dans le traitement de la lombalgie depuis plus de cent ans. La recherche dans ce domaine a commencé au milieu du XXème siècle puis s'est développée exponentiellement jusqu'à nos jours. La première étude de cette thèse a eu pour but de passer en revue cette abondante littérature scientifique. Il en est ressorti que l'exercice est un moyen efficace de prévention primaire et secondaire de la lombalgie. En tant que modalité de traitement, l'exercice permet de diminuer l'incapacité et la douleur et d'améliorer la condition physique et le statut professionnel des patients lombalgiques subaigus et chroniques. Parmi les caractéristiques de l'exercice, la supervision est essentielle. Des investigations ultérieures sont nécessaires afin d'identifier des sous-groupes de patients répondant favorablement à d'autres caractéristiques de l'exercice. L'exercice est souvent utilisé dans l'optique de maintenir les résultats obtenus à la suite d'un traitement, bien que peu d'études s'y soient penchées. La deuxième partie de cette thèse a eu pour objectifs d'évaluer l'efficacité d'un programme d'exercice (PE) suivi par des patients lombalgiques chroniques ayant complété une restauration fonctionnelle multidisciplinaire (RFM), en comparaison avec le suivi classique (SC) consistant simplement à encourager les patients à adopter un quotidien aussi actif que possible par la suite. Les résultats ont montré que les améliorations obtenues au terme de RFM étaient maintenues par les deux groupes à un an de suivi. Bien qu'aucune différence n'ait été obtenue entre les deux groupes, seul le groupe PE améliorait significativement l'incapacité et l'endurance isométrique des muscles du tronc. Une analyse économique a ensuite été réalisée afin d'évaluer la rentabilité de PE. L'évaluation de la qualité de vie des patients au terme de RFM et à un an de suivi permettait d'estimer les années de vie ajustées par leur qualité (QALYs) gagnées par chaque groupe. Les coûts directs (visites chez le médecin, spécialiste, physio, autres) et indirects (jours d'absence au travail) étaient estimés avant RFM et à un an de suivi à l'aide d'un agenda. Aucune différence significative n'était obtenue entre les groupes. Une mince différence de QALYs en faveur de PE ne se traduisait néanmoins pas en bénéfices mesurables. La recherche future devrait s'attacher à identifier un ou des sous-groupe(s) de patients pour lesquels SC ne permet pas de maintenir à long terme les améliorations obtenues au terme de RFM, et pour lesquels l'efficacité thérapeutique et la rentabilité économique de PE pourraient être accrues. ABSTRACT Exercise is used to treat low back pain for over a hundred years. Research in this area began in the mid-twentieth century and then grew exponentially until nowadays. The first study of this thesis was aimed to review this abundant scientific literature. It showed that exercise is effective in the primary and secondary prevention of low back pain. As a modality of treatment, exercise can reduce disability and pain and improve physical fitness and professional status of patients with subacute and chronic low back pain. Among different exercise characteristics, supervision is essential. Further investigations are needed to identify subgroups of patients responding positively to other characteristics of exercise. Exercise is often used as a post-treatment modality in order to maintain results over time, although only a few studies addressed this issue directly. The purpose of the second part of this thesis was to evaluate the effectiveness of an exercise program (EP) for patients with chronic low back pain who completed a functional multidisciplinary rehabilitation (FMR), compared to the routine follow-up (RF) which simply consisted of encouraging patients to adopt an active daily life thereafter. The results showed that improvements obtained at the end of FMR were maintained by both groups at one year follow-up. Although no difference was obtained between both groups, only the EP group significantly improved disability and isometric endurance of trunk muscles. An economic analysis was then carried out to assess the cost-effectiveness of EP. Based on the evaluation of patients' quality of life after FMR and at one year follow-up, an estimation of adjusted life years for their quality (QALYs) gained by each group was done. Direct costs (physician, specialist, physiotherapist, other therapists visits) and indirect costs (days off work) were measured before FMR and at one year follow-up using a cost diary. No significant difference was obtained between both groups. A slight difference in QALYs in favour of EP did yet not translate into measurable benefits. Future research should focus on identifying subgroups of patients for which RF is insufficient to reach long-term improvements after FMR, and for which the therapeutic effectiveness and cost-effectiveness of EP could be increased.

Ruling out coronary heart disease in primary care patients with chest pain : a clinical prediction score

ABSTRACT: BACKGROUND: Chest pain raises concern for the possibility of coronary heart disease. Scoring methods have been developed to identify coronary heart disease in emergency settings, but not in primary care. METHODS: Data were collected from a multicenter Swiss clinical cohort study including 672 consecutive patients with chest pain, who had visited one of 59 family practitioners' offices. Using delayed diagnosis we derived a prediction rule to rule out coronary heart disease by means of a logistic regression model. Known cardiovascular risk factors, pain characteristics, and physical signs associated with coronary heart disease were explored to develop a clinical score. Patients diagnosed with angina or acute myocardial infarction within the year following their initial visit comprised the coronary heart disease group. RESULTS: The coronary heart disease score was derived from eight variables: age, gender, duration of chest pain from 1 to 60 minutes, substernal chest pain location, pain increases with exertion, absence of tenderness point at palpation, cardiovascular risks factors, and personal history of cardiovascular disease. Area under the receiver operating characteristics curve was of 0.95 with a 95% confidence interval of 0.92; 0.97. From this score, 413 patients were considered as low risk for values of percentile 5 of the coronary heart disease patients. Internal validity was confirmed by bootstrapping. External validation using data from a German cohort (Marburg, n = 774) revealed a receiver operating characteristics curve of 0.75 (95% confidence interval, 0.72; 0.81) with a sensitivity of 85.6% and a specificity of 47.2%. CONCLUSIONS: This score, based only on history and physical examination, is a complementary tool for ruling out coronary heart disease in primary care patients complaining of chest pain.

Manual therapy followed by specific active exercises versus a placebo followed by specific active exercises on the improvement of functional disability in patients with chronic non specific low back pain: a randomized controlled trial.

BACKGROUND: Recent clinical recommendations still propose active exercises (AE) for CNSLBP. However, acceptance of exercises by patients may be limited by pain-related manifestations. Current evidences suggest that manual therapy (MT) induces an immediate analgesic effect through neurophysiologic mechanisms at peripheral, spinal and cortical levels. The aim of this pilot study was first, to assess whether MT has an immediate analgesic effect, and second, to compare the lasting effect on functional disability of MT plus AE to sham therapy (ST) plus AE. METHODS: Forty-two CNSLBP patients without co-morbidities, randomly distributed into 2 treatment groups, received either spinal manipulation/mobilization (first intervention) plus AE (MT group; n = 22), or detuned ultrasound (first intervention) plus AE (ST group; n = 20). Eight therapeutic sessions were delivered over 4 to 8 weeks. Immediate analgesic effect was obtained by measuring pain intensity (Visual Analogue Scale) before and immediately after the first intervention of each therapeutic session. Pain intensity, disability (Oswestry Disability Index), fear-avoidance beliefs (Fear-Avoidance Beliefs Questionnaire), erector spinae and abdominal muscles endurance (Sorensen and Shirado tests) were assessed before treatment, after the 8th therapeutic session, and at 3- and 6-month follow-ups. RESULTS: Thirty-seven subjects completed the study. MT intervention induced a better immediate analgesic effect that was independent from the therapeutic session (VAS mean difference between interventions: -0.8; 95% CI: -1.2 to -0.3). Independently from time after treatment, MT + AE induced lower disability (ODI mean group difference: -7.1; 95% CI: -12.8 to -1.5) and a trend to lower pain (VAS mean group difference: -1.2; 95% CI: -2.4 to -0.30). Six months after treatment, Shirado test was better for the ST group (Shirado mean group difference: -61.6; 95% CI: -117.5 to -5.7). Insufficient evidence for group differences was found in remaining outcomes. CONCLUSIONS: This study confirmed the immediate analgesic effect of MT over ST. Followed by specific active exercises, it reduces significantly functional disability and tends to induce a larger decrease in pain intensity, compared to a control group. These results confirm the clinical relevance of MT as an appropriate treatment for CNSLBP. Its neurophysiologic mechanisms at cortical level should be investigated more thoroughly. TRIAL REGISTRATION: Trial registration number: NCT01496144.

Impact of a pain protocol including hypnosis in major burns.

BACKGROUND: Pain is a major issue after burns even when large doses of opioids are prescribed. The study focused on the impact of a pain protocol using hypnosis on pain intensity, anxiety, clinical course, and costs. METHODS: All patients admitted to the ICU, aged >18 years, with an ICU stay >24h, accepting to try hypnosis, and treated according to standardized pain protocol were included. Pain was scaled on the Visual Analog Scale (VAS) (mean of daily multiple recordings), and basal and procedural opioid doses were recorded. Clinical outcome and economical data were retrieved from hospital charts and information system, respectively. Treated patients were matched with controls for sex, age, and the burned surface area. FINDINGS: Forty patients were admitted from 2006 to 2007: 17 met exclusion criteria, leaving 23 patients, who were matched with 23 historical controls. Altogether patients were 36+/-14 years old and burned 27+/-15%BSA. The first hypnosis session was performed after a median of 9 days. The protocol resulted in the early delivery of higher opioid doses/24h (p<0.0001) followed by a later reduction with lower pain scores (p<0.0001), less procedural related anxiety, less procedures under anaesthesia, reduced total grafting requirements (p=0.014), and lower hospital costs per patient. CONCLUSION: A pain protocol including hypnosis reduced pain intensity, improved opioid efficiency, reduced anxiety, improved wound outcome while reducing costs. The protocol guided use of opioids improved patient care without side effects, while hypnosis had significant psychological benefits.
