Anxiety, depression and school absenteeism in youth with chronic or episodic headache.

BACKGROUND: Chronic daily headache (CDH) in children has been documented in general and clinical populations. Comorbid psychological conditions, risk factors and functional outcomes of CDH in children are not well understood. OBJECTIVES: To examine anxiety and depression, associated risk factors and school outcomes in a clinical population of youth with CDH compared with youth with episodic headache (EH). METHODS: Data regarding headache characteristics, anxiety, depression and missed school days were collected from 368 consecutive patients eight to 17 years of age, who presented with primary headache at a specialized pediatric headache centre. RESULTS: A total of 297 patients (81%) were diagnosed with EH and 71 were diagnosed with CDH. Among those with CDH, 78.9% presented with chronic tension-type headache and 21.1% with chronic migraine (CM). Children with CDH had a higher depression score than the standardized reference population. No difference was observed for anxiety or depression scores between children with CDH and those with EH. However, children with CM were more anxious and more depressed than those with chronic tension-type headache. Youth experiencing migraine with aura were three times as likely to have clinically significant anxiety scores. Headache frequency and history were not associated with psychopathological symptoms. Children with CDH missed school more often and for longer periods of time. CONCLUSIONS: These findings document the prevalence of anxiety, depression and school absenteeism in youth with CDH or EH. The present research also extends recent studies examining the impact of aura on psychiatric comorbidity and the debate on CM criteria.

Can smaller-scale comprehensive cancer centers provide outstanding care in abdominal and thoracic pediatric solid tumor surgery? Results of a 14-year retrospective single-center analysis.

PURPOSE: Quality of care and its measurement represent a considerable challenge for pediatric smaller-scale comprehensive cancer centers (pSSCC) providing surgical oncology services. It remains unclear whether center size and/or yearly case-flow numbers influence the quality of care, and therefore impact outcomes for this population of patients. PATIENTS AND METHODS: We performed a 14-year, retrospective, single-center analysis, assessing adherence to treatment protocols and surgical adverse events as quality indicators in abdominal and thoracic pediatric solid tumor surgery. RESULTS: Forty-eight patients, enrolled in a research-associated treatment protocol, underwent 51 cancer-oriented surgical procedures. All the protocols contain precise technical criteria, indications, and instructions for tumor surgery. Overall, compliance with such items was very high, with 997/1,035 items (95 %) meeting protocol requirements. There was no surgical mortality. Twenty-one patients (43 %) had one or more complications, for a total of 34 complications (66 % of procedures). Overall, 85 % of complications were grade 1 or 2 according to Clavien-Dindo classification requiring observation or minor medical treatment. Case-sample and outcome/effectiveness data were comparable to published series. Overall, our data suggest that even with the modest caseload of a pSSCC within a Swiss tertiary academic hospital, compliance with international standards can be very high, and the incidence of adverse events can be kept minimal. CONCLUSION: Open and objective data sharing, and discussion between pSSCCs, will ultimately benefit our patient populations. Our study is an initial step towards the enhancement of critical self-review and quality-of-care measurements in this setting.

Sedation and analgesia for colonoscopy: patient tolerance, pain, and cardiorespiratory parameters.

BACKGROUND: Colonoscopy is generally performed with the patient sedated and receiving analgesics. However, the benefit of the most often used combination of intravenous midazolam and pethidine on patient tolerance and pain and its cardiorespiratory risk have not been fully defined. METHODS: In this double-blind prospective study, 150 outpatients undergoing routine colonoscopy were randomly assigned to receive either (1) low-dose midazolam (35 micrograms/kg) and pethidine (700 micrograms/kg in 48 patients, 500 micrograms/kg in 102 patients), (2) midazolam and placebo pethidine, or (3) pethidine and placebo midazolam. RESULTS: Tolerance (visual analog scale, 0 to 100 points: 0 = excellent; 100 = unbearable) did not improve significantly more in group 1 compared with group 2 (7 points; 95% confidence interval [-2-17]) and group 3 (2 points; 95% confidence interval [-7-12]). Similarly, pain was not significantly improved in group 1 as compared with the other groups. Male gender (p < 0.001) and shorter duration of the procedure (p = 0.004), but not amnesia, were associated with better patient tolerance and less pain. Patient satisfaction was similar in all groups. Oxygen desaturation and hypotension occurred in 33% and 11%, respectively, with a similar frequency in all three groups. CONCLUSIONS: In this study, the combination of low-dose midazolam and pethidine does not improve patient tolerance and lessen pain during colonoscopy as compared with either drug given alone. When applying low-dose midazolam, oxygen desaturation and hypotension do not occur more often after combined use of both drugs. For the individual patient, sedation and analgesia should be based on the endoscopist's clinical judgement.

Indicators used by clinicians to assess pain in the brain injured

INTRODUCTION. The assessment of pain in critically ill brain-injured patients is challenging for health professionals. In addition to be unable to self-report, the confused and stereotyped behaviors of these patients are likely to alter their ''normal'' pain responses. Therefore, the pain indicators observed in the general critically ill population may not be appropriate. OBJECTIVES. To identify behavioral and physiological indicators used by clinicians to assess pain in critically ill brain-injured patients who are unable to self-report. METHODS.Amixed-method design was used with the first step being the combination of the results of an integrative literature review with the results of nominal groups of 12 nurses and four physicians. The second step involved a web-based survey to establish content validity. Fourteen experts (clinicians and academics) from three French speaking European countries rated the relevance of each indicator. A content validity index (CVI) was computed for each indicator (I-CVI) and for each category (S-CVI). RESULTS. The first step generated 52 indicators. These indicators were classified into six categories: facial expressions, position/movement, muscle tension, vocalization, compliance with ventilator, and physiological indicators. In the second step, the agreement between raters was high with an Intraclass Correlation Coefficient of 0.88 (95% CI 0.83-0.92). The I-CVIs ranged from 0.07 to 1. Indicators with an I-CVI below 0.5 (n = 12) were not retained, resulting in a final list of 30 indicators. The CVI for this final list was 0.75 with categories ranging from 0.67 (compliance with ventilation) to 0.87 (vocalization). CONCLUSIONS. This process identified specific pain indicators for critically ill braininjured patients. Further evaluation is in progress to test the validity and relevance of these indicators in the clinical setting.

Deep sclerectomy combined with trabeculectomy in pediatric glaucoma.

PURPOSE: To evaluate the outcomes of combined deep sclerectomy and trabeculectomy (penetrating deep sclerectomy) in pediatric glaucoma. DESIGN: Retrospective, nonconsecutive, noncomparative, interventional case series. PARTICIPANTS: Children suffering from pediatric glaucoma who underwent surgery between March 1997 and October 2006 were included in this study. METHODS: A primary combined deep sclerectomy and trabeculectomy was performed in 35 eyes of 28 patients. Complete examinations were performed before surgery, postoperatively at 1 and 7 days, at 1, 2, 3, 4, 6, 9, and 12 months, and then every 6 months after surgery. MAIN OUTCOME MEASURES: Surgical outcome was assessed in terms of intraocular pressure (IOP) change, additional glaucoma medication, complication rate, need for surgical revision, as well as refractive errors, best-corrected visual acuity (BCVA), and corneal clarity and diameters. RESULTS: The mean age before surgery was 3.6+/-4.5 years, and the mean follow-up was 3.5+/-2.9 years. The mean preoperative IOP was 31.9+/-11.5 mmHg. At the end of follow-up, the mean IOP decreased by 58.3% (P&lt;0.005), and from 14 patients with available BCVA 8 patients (57.1%) achieved 0.5 (20/40) or better, 3 (21.4%) 0.2 (20/100), and 2 (14.3%) 0.1 (20/200) in their better eye. The mean refractive error (spherical equivalent [SE]) at final follow-up visits was +0.83+/-5.4. Six patients (43%) were affected by myopia. The complete and qualified success rates, based on a cumulative survival curve, after 9 years were 52.3% and 70.6%, respectively (P&lt;0.05). Sight-threatening complications were more common (8.6%) in refractory glaucomas. CONCLUSIONS: Combined deep sclerectomy and trabeculectomy is an operative technique developed to control IOP in congenital, secondary, and juvenile glaucomas. The intermediate results are satisfactory and promising. Previous classic glaucoma surgeries performed before this new technique had less favorable results. The number of sight-threatening complications is related to the severity of glaucoma and number of previous surgeries.

Cavernomas and brain cysts as treatment-related sequelae in survivors of pediatric brain tumors

Cavernomas after radiotherapy, developing in irradiated children treated for malignant brain tumors, are capillary malformations that are frquently asymptomatic and benign in their evolution. However, in some children this can lead to haemorrhage, which can cause symptoms and need a surgical intervention. Although there is increasing evidence of cavernoma as a possible long term sequelae after radiotherapy, there is still information needed concerning very long follow-up. Different groups studied this problem focusing on incidence and the lag time radiotherapy and the appearance of cavernomas. Results showed that the period can last a long time and the cumulative incidence increases over the years, but the numbers vary between the different publications. More recently researchers tried to compare several predictive factors with the incidence of cavernomas, such as age at radiotherapy, gender, kind of cancer and chemotherapy. No relation has been recorded except a growing incidence when the radiotherapy was started before the age of ten. Reason of the study : The observations reported until now comprised a very heterogenous cohort of patients. No study has ever been made with patients affected only by malignant brain tumors which are typical in a children. As for the studied predictive factors, no publication described the technical aspect of radiotherapy. Objectives: To study a population of pediatric patients children with only malignant brain tumors in order tp calculate the incidence of cavernomas after radiotherapy and their evolution over a longer period compared to so far published researches. To analyse known predictive factors such as age of children at the moment of the radiotherapy, gender, and kind of cancer. To study extensively the role technical aspects of radiotherapy in the occurrence of cavernomas. Methodology: Retrospective study of a group of 62 children irradiated at the CHUV (Lausanne, Switzerland) between 1975 and 2010 due to the following malignant brain cancers: medulloblastoma, ependymoma, PNET. The images of IRM post radiotherapy will be analysed by a neuroradiologist and a radiotherapist will interpret the radiotherapy data. Expected results: We expect to find relations between the incidence of cavernomas post radiotherapy and the predictive factors including different techniques of radiotherapy and consequently to define the best long-term follow up of the children at risk.

A Prospective Multicenter SPOG 2003 FN Study of Microbiologically Defined Infections in Pediatric Cancer Patients with Fever and Neutropenia.

BACKGROUND: Fever and neutropenia (FN) often complicate anticancer treatment and can be caused by potentially fatal infections. Knowledge of pathogen distribution is paramount for optimal patient management. METHODS: Microbiologically defined infections (MDI) in pediatric cancer patients presenting with FN by nonmyeloablative chemotherapy enrolled in a prospective multi-center study were analyzed. Effectiveness of empiric antibiotic therapy in FN episodes with bacteremia was assessed taking into consideration recently published treatment guidelines for pediatric patients with FN. RESULTS: MDI were identified in a minority (22%) of pediatric cancer patients with FN. In patients with, compared to without MDI, fever (median, 5 [IQR 3-8] vs. 2 [IQR1-3] days, p < 0.001) and hospitalization (10 [6-14] vs. 5 [3-8] days, p < 0.001) lasted longer, transfer to the intensive care unit was more likely (13 of 95 [14%] vs. 7 of 346 [2.0%], p < 0.001), and antibiotics were given longer (10 [7-14] vs. 5 [4-7], p < 0.001). Empiric antibiotic therapy in FN episodes with bacteremia was highly effective if not only intrinsic and reported antimicrobial susceptibilities were considered but the purposeful omission of coverage for coagulase negative staphylococci and enterococci was also taken into account (81% [95%CI 68 - 90] vs. 96.6% [95%CI 87 - 99.4], p = 0.004) CONCLUSIONS: MDI were identified in a minority of FN episodes but they significantly affected management and the clinical course of pediatric cancer patients. Compliance with published guidelines was associated with effectiveness of empiric antibiotic therapy in FN episodes with bacteremia.

Consensus interdisciplinaire CHUV-HUG sur la prise en charge des douleurs du dos. Son application lausannoise dans la filière du dos [Inter-hospital CHUV-HUG medical consensus of back pain management. Its application in care pathways within CHUV of Lausanne].

Back pain is a considerable economical burden in industrialised countries. Its management varies widely across countries, including Switzerland. Thus, the University Hospital and University of Lausanne (CHUV) recently improved intern processes of back pain care. In an already existing collaborative context, the two university hospitals in French-speaking Switzerland (CHUV, University Hospital of Geneva), felt the need of a medical consensus, based on a common concept. This inter-hospital consensus produced three decisional algorithms that bear on recent concepts of back pain found in literature. Eventually, a fast track was created at CHUV, to which extern physicians will have an organised and rapid access. This fast track aims to reduce chronic back pain conditions and provides specialised education for general practitioners-in-training.

Notfälle in der Pädiatrie [Pediatric emergencies]

We describe the most frequent emergencies in pediatrics and discuss their differential diagnosis and therapy. Dyspnea, shock, coma, convulsions, infectious CNS affections, head injury and burns are reported in detail. The importance of correct diagnosis and correct clinical assessment is emphasized, as they influence therapy and further management of the patients.

Pain assessment in PICU and NICU: Have we got it right?

Pain assessment in critically ill infants and nonverbal children remains a challenge for health professionals. Despite the numerous pain observational measures that have been developed or adapted for infants and children with impaired communication, pain prevalence in paediatric and neonatal intensive care unit remains too high. As pain assessment has been recognised as a pre-requisite for appropriate pain management, much effort was put in the validation or the adaptation of pain measures with little emphasis on implementation of these instruments into practice. Only a few studies demonstrated the benefit of using standardised protocols for the management of pain to guide practice with variable effects. When standardised protocols are undeniably useful in practice, they do not replace health professionals' clinical reasoning necessary to care for individuals. The diversity of the PICU population makes that pain scores need to be interpreted within its clinical context. This session will present pain assessment as a complex transaction that describes structured clinical reasoning from expert nurses that goes beyond the "silver" standard of hetero-evaluation of pain in non-communicative children. Besides pain scores, several patients and nurses factors play a major role in making decisions about analgesia and/or sedation. Patient's clinical instability, change in patient's clinical status, source for observed agitated behaviour, patient's known reactions to analgesia and sedation and anticipation of risks are factors that should be taken into account when implementing pain assessment and management guidelines in PICU and NICU.

Epaule douloureuse: prise en charge ambulatoire [Shoulder pain in ambulatory practice].

Scapulalgias or omalgias are a frequent complaint, with more than half of them being linked to an injury of the rotators cuff. As they often become chronic, omalgias result in higher rates of absenteeism and significant health care costs. Scapulalgias have three main causes: posttraumatic, intrinsic of the joint, or extrinsic. The extrinsic omalgias, either of neurologic, cardiovascular, pulmonary, or abdominal etiology, require swift identification, as their treatment is often an emergency. Most of the scapulalgias can be treated conservatively. Main factors of poor prognosis are old age, women gender and associated cervicalgias.

Lessons learned after 2 full scale disaster exercises in a Swiss pediatric hospital

Introduction: Following a disaster, up to 50% of mass casualties are children. The number of disaster increases worldwide, including in Switzerland. Following national order, the mapping of the various risks of disaster in Switzerland will be completed by the end of 2012. Pre-hospital disaster drills and plans are well established and regularly tested. In-hospital disaster plans are much less frequently tested, if only available. Pediatric in-hospital full scale disaster exercises have never been reported in Switzerland. Based on our local constraints, we set up and evaluated a disaster plan during two full scale exercises. Methods: In a university hospital treating more than 35 000 pediatric emergencies per year, two exercises involving mock victims of a disaster aged 9 to 14 years old were successively set up over a period of 3 years. The exercises were planned during the day, without modification of the normal emergency room activities. The hospital staff was informed and trained in advance. Variables such as the alarm timing and transmission, triage set-up and function, special disaster medical records utilization, communication and victims' identification were assessed. Family members participated in the second exercise. An evaluation team observed and record exercises activities, identifying strength and weaknesses. Results: On two separate occasions, a total of 44 mock patients participated, were triaged, admitted and treated in the hospital according to usual standards of care. Alarm transmission was not appropriate during the first exercise. Triage overload occurred on one occasion. In-hospital communication needed readjustment. Identification and in-hospital tracking of the children remained problematic. Hospital employees showed great enthusiasm and stressed the positive effect of full scale exercises on their knowledge of the hospital disaster plan. Conclusions: Performing real life disaster exercises in a pediatric hospital was very beneficial. The disaster plan was adapted to local needs and updated accordingly. An alarm transmission protocol was elaborated and tested. Triage set-up was adapted and tested. A hospital identification plan for injured children was created and tested. Full scale hospital exercises evaluating disaster plans revealed several weaknesses in the system. Practice readjustments based on local experience were made. A tested pediatric disaster plan adapted to local constraints could minimize chaos, optimize care and support in the event of a real disaster. Children's identification and family reunification following a disaster remains a challenge.

La fonction de Moi auxiliaire dans la prise en charge des douloureux chroniques [The role of the auxiliary ego in the care of the chronic pain patient]

La prise en charge des patients souffrant de douleurs chroniques, à l'interface entre corps et psyché, nécessite une approche globale et souvent un réseau de soins coordonnés, contenant et stable. La psychiatrie de liaison a naturellement trouvé sa place dans ce réseau de soins spécifiques auprès des différents soignants impliqués. Les réflexions issues de cette expérience ont pour objectif de mieux comprendre le rôle thérapeutique des soignants et font émerger la notion de Moi auxiliaire comme élément clé dans le traitement de ces patients. Dans cet article, nous reprendrons les fondements historiques et conceptuels de la fonction de Moi auxiliaire pour nous intéresser à ses différentes applications dans ces prises en charge : consultation médicale, psychothérapie individuelle ou de groupe, colloque interdisciplinaire. The management of the patient suffering from chronic pain, situated on the interface between body and psyche, necessitates a global approach and often a coordinated, stable and containing network of care. Liaison psychiatry has become part of this network, together with various health care professionals from somatic disciplines. Based on these experiences, this article aims to better understand the therapeutic role of those who take care of the chronic pain patient by identifying the auxiliary ego as a key element of care. The historical development and conceptual framework of the auxiliary ego are utilized to highlight its roles in the different aspects of care of these patients:in the medical consultation, individual psychotherapy, group psychotherapy and in the interdisciplinary meetings.
