Conocimiento de la ley y preparación del personal sanitario sobre el proceso asistencial de la muerte.

The aims of this study were to ascertain the perception that health professionals (doctors, nurses and nursing assistants) have about their preparation for the care of terminally ill patients and to determine their knowledge about palliative care legislation. This cross sectional study was performed at a hospital in Granada (Spain); we administered an ad hoc questionnaire. The results indicated that although most of the staff had worked with terminally ill patients, only half believed that they have been trained to care for them. A significant proportion stated that they did not know about the current palliative care legislation. Most professionals would question the withdrawal of therapies for the maintenance of life; most of them are also unaware of the mechanism for reporting on the completion of a Living Will, as well as a Plan for Palliative Care in Andalusia (Spain).

Optimizing patient-ventilator synchrony during invasive ventilator assist in children and infants remains a difficult task.

OBJECTIVES: To document and compare the prevalence of asynchrony events during invasive-assisted mechanical ventilation in pressure support mode and in neurally adjusted ventilatory assist in children. DESIGN: Prospective, randomized, and crossover study. SETTING: Pediatric and Neonatal Intensive Care Unit, University Hospital of Geneva, Switzerland. PATIENTS: Intubated and mechanically ventilated children, between 4 weeks and 5 years old. INTERVENTIONS: Two consecutive ventilation periods (pressure support and neurally adjusted ventilatory assist) were applied in random order. During pressure support, three levels of expiratory trigger setting were compared: expiratory trigger setting as set by the clinician in charge (PSinit), followed by a 10% (in absolute values) increase and decrease of the clinician's expiratory trigger setting. The pressure support session with the least number of asynchrony events was defined as PSbest. Therefore, three periods were compared: PSinit, PSbest, and neurally adjusted ventilatory assist. Asynchrony events, trigger delay, and inspiratory time in excess were quantified for each of them. MEASUREMENTS AND MAIN RESULTS: Data from 19 children were analyzed. Main asynchrony events during PSinit were autotriggering (3.6 events/min [0.7-8.2]), ineffective efforts (1.2/min [0.6-5]), and premature cycling (3.5/min [1.3-4.9]). Their number was significantly reduced with PSbest: autotriggering 1.6/min (0.2-4.9), ineffective efforts 0.7/min (0-2.6), and premature cycling 2/min (0.1-3.1), p < 0.005 for each comparison. The median asynchrony index (total number of asynchronies/triggered and not triggered breaths ×100) was significantly different between PSinit and PSbest: 37.3% [19-47%] and 29% [24-43%], respectively, p < 0.005). With neurally adjusted ventilatory assist, all types of asynchrony events except double-triggering and inspiratory time in excess were significantly reduced resulting in an asynchrony index of 3.8% (2.4-15%) (p < 0.005 compared to PSbest). CONCLUSIONS: Asynchrony events are frequent during pressure support in children despite adjusting the cycling off criteria. Neurally adjusted ventilatory assist allowed for an almost ten-fold reduction in asynchrony events. Further studies should determine the clinical impact of these findings.

Superior vena cava syndrome caused by invasive epidermoid carcinoma.

Lung cancer is the most frequent cause of superior vena cava (SVC) syndrome. Malignant SVC syndrome is generally considered a contraindication to curative resection, although palliative bypasses are done for symptoms that do not respond to medical therapy. However, a majority of patients with such advanced disease die of complications caused by the primary tumor rather than distant metastasis. We present the case of one patient with lung cancer invading the mediastinal structures. Combined resection and replacement of the SVC with a segment of Dacron vascular graft was performed. Postoperative survival time was 24 months.

Chimioradiothérapie postopératoire des cancers des voies aérodigestives : vers un nouveau standard [Post-operative radiochemotherapy of the head and neck: Towards new standards?]

Head and neck squamous cell carcinomas are frequently diagnosed at an advanced stage. Their treatment remains controversial, and has to be multidisciplinary. External beam radiotherapy is a recognized treatment option after radical curative surgery in order to improve local control. Different adjuvant treatment options have been studied in order to improve the outcome of these patients. We review in this paper the different prognostic factors indicating an adjuvant treatment and the interest of treatment intensification in bad prognostic patients.

Delay of extubation in neonates and children after cardiac surgery: impact of ventilator-associated pneumonia.

OBJECTIVE: This study was undertaken to determine the delay of extubation attributable to ventilator-associated pneumonia (VAP) in comparison to other complications and complexity of surgery after repair of congenital heart lesions in neonates and children. METHODS: Cohort study in a pediatric intensive care unit of a tertiary referral center. All patients who had cardiac operations during a 22-month period and who survived surgery were eligible (n = 272, median age 1.3 years). Primary outcome was time to successful extubation. Primary variable of interest was VAP Surgical procedures were classified according to complexity. Cox proportional hazards models were calculated to adjust for confounding. Potential confounders comprised other known risk factors for delayed extubation. RESULTS: Median time to extubation was 3 days. VAP occurred in 26 patients (9.6%). The rate of VAP was not associated with complexity of surgery (P = 0.22), or cardiopulmonary bypass (P = 0.23). The adjusted analysis revealed as further factors associated with delayed extubation: other respiratory complications (n = 28, chylothorax, airway stenosis, diaphragm paresis), prolonged inotropic support (n = 48, 17.6%), and the need for secondary surgery (n = 51, 18.8%; e.g., re-operation, secondary closure of thorax). Older age promoted early extubation. The median delay of extubation attributable to VAP was 3.7 days (hazards ratio HR = 0.29, 95% CI 0.18-0.49), exceeding the effect size of secondary surgery (HR = 0.48) and other respiratory complications (HR = 0.50). CONCLUSION: VAP accounts for a major delay of extubation in pediatric cardiac surgery.

Effectiveness of chronic obstructive pulmonary disease-management programs: systematic review and meta-analysis

BACKGROUND: Disease-management programs may enhance the quality of care provided to patients with chronic diseases, such as chronic obstructive pulmonary disease (COPD). The aim of this systematic review was to assess the effectiveness of COPD disease-management programs. METHODS: We conducted a computerized search of MEDLINE, EMBASE, CINAHL, PsychINFO, and the Cochrane Library (CENTRAL) for studies evaluating interventions meeting our operational definition of disease management: patient education, 2 or more different intervention components, 2 or more health care professionals actively involved in patients' care, and intervention lasting 12 months or more. Programs conducted in hospital only and those targeting patients receiving palliative care were excluded. Two reviewers evaluated 12,749 titles and fully reviewed 139 articles; among these, data from 13 studies were included and extracted. Clinical outcomes considered were all-cause mortality, lung function, exercise capacity (walking distance), health-related quality of life, symptoms, COPD exacerbations, and health care use. A meta-analysis of exercise capacity and all-cause mortality was performed using random-effects models. RESULTS: The studies included were 9 randomized controlled trials, 1 controlled trial, and 3 uncontrolled before-after trials. Results indicate that the disease-management programs studied significantly improved exercise capacity (32.2 m, 95% confidence interval [CI], 4.1-60.3), decreased risk of hospitalization, and moderately improved health-related quality of life. All-cause mortality did not differ between groups (pooled odds ratio 0.84, 95% CI, 0.54-1.40). CONCLUSION: COPD disease-management programs modestly improved exercise capacity, health-related quality of life, and hospital admissions, but not all-cause mortality. Future studies should explore the specific elements or characteristics of these programs that bring the greatest benefit.

The existence of nursing in caring for terminally ills’life: a phenomenological study

By taking care of cancer patients in their process of end of life, nursing experience situations of suffering before the anguish of others. This study aimed to understand the meaning and significance attributed by the nurses from the palliative care cancer hospital. This is a phenomenological research, grounded in Heidegger’s thinking, performed with 13 nurses, who work at Oncology hospitalward, through semi-structured interviews, which were analyzed according to the steps recommended by Josgrilberg. From understanding the statementsof the subjects, two ontological themesemerged: Feeling satisfaction and love in the care offered and Feeling anger and inabilitytowards terminally ill patients.We inferred that working in Oncology Ward is something rewarding for these professionals, but it entails physical and mental suffering, from feeling helpless before the death-dying process. Thus, we showedthat nursing professionals need to be recognized as human beings and as such, also deserving of care.

16q24.1 microdeletion in a premature newborn: Usefulness of array-based comparative genomic hybridization in persistent pulmonary hypertension of the newborn.

OBJECTIVE:: Report of a 16q24.1 deletion in a premature newborn, demonstrating the usefulness of array-based comparative genomic hybridization in persistent pulmonary hypertension of the newborn and multiple congenital malformations. DESIGN:: Descriptive case report. SETTING:: Genetic department and neonatal intensive care unit of a tertiary care children's hospital. INTERVENTIONS:: None. PATIENT:: We report the case of a preterm male infant, born at 26 wks of gestation. A cardiac malformation and bilateral hydronephrosis were diagnosed at 19 wks of gestation. Karyotype analysis was normal, and a 22q11.2 microdeletion was excluded by fluorescence in situ hybridization analysis. A cesarean section was performed due to fetal distress. The patient developed persistent pulmonary hypertension unresponsive to mechanical ventilation and nitric oxide treatment and expired at 16 hrs of life. MEASUREMENTS AND MAIN RESULTS:: An autopsy revealed partial atrioventricular canal malformation and showed bilateral dilation of the renal pelvocaliceal system with bilateral ureteral stenosis and annular pancreas. Array-based comparative genomic hybridization analysis (Agilent oligoNT 44K, Agilent Technologies, Santa Clara, CA) showed an interstitial microdeletion encompassing the forkhead box gene cluster in 16q24.1. Review of the pulmonary microscopic examination showed the characteristic features of alveolar capillary dysplasia with misalignment of pulmonary veins. Some features were less prominent due to the gestational age. CONCLUSIONS:: Our review of the literature shows that alveolar capillary dysplasia with misalignment of pulmonary veins is rare but probably underreported. Prematurity is not a usual presentation, and histologic features are difficult to interpret. In our case, array-based comparative genomic hybridization revealed a 16q24.1 deletion, leading to the final diagnosis of alveolar capillary dysplasia with misalignment of pulmonary veins. It emphasizes the usefulness of array-based comparative genomic hybridization analysis as a diagnostic tool with implications for both prognosis and management decisions in newborns with refractory persistent pulmonary hypertension and multiple congenital malformations.

Assessing the wish to die in elderly people.

Background: The wish to die has mainly been studied in terminally- ill young adults. In elderly persons, factors associated with the wish to die are likely to differ from those observed in younger people. Since the most frequently used scale -"The Schedule ofAttitudes Toward Hastened Death" (SAHD, Rosenfeld et al., 2000)- was previously used in terminally ill cancer or AIDS patients, its use in elderly people suffering from multiple comorbidities is problematic. The objectives of this study were 1) to adapt the SAHD for use in elderly people, 2) to develop a new instrument to assess patients' attitudes towards death 3) to test the relevance/acceptability of these instruments. Methods:An adapted version of the SAHD to the elderly population (SAHD-OLD) was obtained by analyzing all items of the instrument instrument in an interdisciplinary group of experts in geriatric care. Items were modified according to their relevance in elderly population. An instrument to assess patients' attitudes towards death was built on previous qualitative work performed by Schroepfer. These 2 instruments were subjected to cognitive testing in a convenience sample of 11 community-dwelling people (median age = 82 years; range 76-91). Results: The SAHD-OLD was obtained by modifying those items addressing palliative care issues (eg. irreversible consequences of stopping treatment) and systematically replacing "illness/disease" by "health problems". We expressed in statements the 6 categories identified by Schroepfer, and created instructions asking respondents to describe their current attitude towards death (Adapted Schroepfer). During cognitive testing, our sample assessed the SAHD-OLD and the Adapted Schroepfer as relevant for elderly people. Respondents judged these 2 instruments acceptable and appreciated the direct manner in which they addressed end of life issues. The opportunity to speak openly on this topic was welcomed. Conclusions: The SAHD-OLD and the Adapted Schroepfer seem promising instruments to assess the wish to die in elderly people suffering from multiple comorbidities. Preliminary results show good comprehension, high relevance and acceptability. Psychometric properties of the SAHD-OLD are currently being tested in a large sample of patients.

Investigating barriers in HIV-testing oncology patients. The IBITOP study: phase I.

BACKGROUND: Since the advent of combined antiretroviral therapy (ART), the incidence of non-AIDS-defining cancers (non-ADCs) among HIV-positive patients is rising. We previously described HIV testing rates of <5% in our oncology centre, against a local HIV prevalence of 0.4% (1). We have since worked with the Service of Oncology to identify, how HIV testing can be optimized, we have conducted a study on investigating barriers in HIV-testing oncology patients (IBITOP) among treating oncologists and their patients. METHODS: After an initial two-month pilot study to examine feasibility (2), we conducted the first phase of the IBITOP study between 1st July and 31st October 2013. Patients of unknown HIV status, newly diagnosed with solid-organ non-AIDS-defining cancer, and treated at Lausanne University Hospital were invited to participate. Patients were offered HIV testing as a part of their initial oncology work-up. Oncologist testing proposals and patient acceptance were the primary endpoints. RESULTS: Of 235 patients with a new oncology diagnosis, 10 were excluded (7 with ADCs and 3 of known HIV-positive status). Mean age was 62 years; 48% were men and 71% were Swiss. Of 225 patients, 75 (33%) were offered HIV testing. Of these, 56 (75%) accepted, of whom 52 (93%) were tested. A further ten patients were tested (without documentation of being offered a test), which gave a total testing rate of 28% (62/225). Among the 19 patients who declined testing, reasons cited included self-perceived absence of HIV risk, previous testing and palliative care. Of the 140 patients not offered HIV testing and not tested, reasons were documented for 35 (25%), the most common being previous testing and follow-up elsewhere. None of the 62 patients HIV tested had a reactive test. CONCLUSIONS: In this study, one third of patients seen were offered testing and the HIV testing rate was fivefold higher than that of previously observed in this service. Most patients accepted testing when offered. As HIV-positive status impacts on the medical management of cancer patients, we recommend that HIV screening should be performed in settings, where HIV prevalence is >0.1%. Phase II of the IBITOP study is now underway to explore barriers to HIV screening among oncologists and patients following the updated national HIV testing guidelines which recommend testing in non-ADC patients undergoing chemotherapy.

Atelosteogenesis Type 2

Disease characteristics. Clinical features of atelosteogenesis type 2 (AO2) include rhizomelic limb shortening with normal-sized skull, hitchhiker thumbs, small chest, protuberant abdomen, cleft palate, and distinctive facial features (midface hypoplasia, depressed nasal bridge, epicanthus, micrognathia). Other typical findings are ulnar deviation of the fingers, gap between the first and second toes, and clubfoot. AO2 is lethal at birth or shortly thereafter because of pulmonary hypoplasia and tracheobronchomalacia. Diagnosis/testing. The diagnosis of AO2 rests on a combination of clinical, radiologic, and histopathologic features. SLC26A2 (DTDST) is the only gene currently known to be associated with AO2. The diagnosis can be confirmed by molecular genetic testing of SLC26A2, which is clinically available. Management. Treatment of manifestations: palliative care for liveborns. Genetic counseling. AO2 is inherited in an autosomal recessive manner. At conception, each sib of a proband with AO2 has a 25% chance of being affected, a 50% chance of being an asymptomatic carrier, and a 25% chance of being unaffected and not a carrier. Once an at-risk sib is known to be unaffected, the risk of his/her being a carrier is 2/3. Prenatal diagnosis for pregnancies at 25% risk is possible. Carrier testing for at-risk relatives and prenatal testing for pregnancies at increased risk are possible if both disease-causing alleles in the family are known and the carrier status of the parents has been confirmed. Ultrasound examination early in pregnancy is a reasonable complement or alternative to molecular genetic prenatal diagnosis.

Le carcinome hépatocellulaire: une approche multidisciplinaire [Hepatocellular carcinoma: a multidisciplinary approach]

The treatment of the hepatocellular carcinoma (HCC) is multidisciplinary. Hepatic transplantation offers the best chances of survival for patients with hepatic cirrhosis and HCC. However the indications for transplantation are limited. For patients that do not qualify for liver transplantation, surgical excision and percutaneous ablative treatment can also be curative. Five years survival then reaches 50%. The choice of treatment is based upon the patient's clinical state, the hepatic function and the cancer clinical stage. Follow-up is crucial as recurrences can be treated by following similar algorithms. The efficacy of oncological adjuvant and neoadjuvant treatment is not yet proved.

Achondrogenesis Type 1B.

DISEASE CHARACTERISTICS: Clinical features of achondrogenesis type 1B (ACG1B) include extremely short limbs with short fingers and toes, hypoplasia of the thorax, protuberant abdomen, and hydropic fetal appearance caused by the abundance of soft tissue relative to the short skeleton. The face is flat, the neck is short, and the soft tissue of the neck may be thickened. Death occurs prenatally or shortly after birth. DIAGNOSIS/TESTING: The diagnosis of ACG1B rests on a combination of clinical, radiologic, and histopathologic features. SLC26A2 (DTDST) is the only gene known to be associated with ACG1B. Molecular genetic testing is available on a clinical basis. MANAGEMENT: Treatment of manifestations: palliative care for liveborn neonates. GENETIC COUNSELING: ACG1B is inherited in an autosomal recessive manner. At conception, each sib of a proband with ACG1B has a 25% chance of being affected, a 50% chance of being an asymptomatic carrier, and a 25% chance of being unaffected and not a carrier. Once an at-risk sib is known to be unaffected, the risk of his/her being a carrier is 2/3. Carrier testing for at-risk relatives and prenatal testing for pregnancies at increased risk are possible if both disease-causing alleles in the family are known and the carrier status of the parents has been confirmed. Ultrasound examination after 14-15 weeks' gestation can be diagnostic.
