Com influencia la pràctica Dalcroze en l'estimulacio de les diferents capacitats dels infants

Aquest treball consta d’un procés d’investigació en el qual hi podem trobar la corroboració de la pregunta inicial sobre com influencia la pràctica Dalcroze en l’estimulació de les diferents capacitats dels infants. Aquest mètode consisteix en estimular la coordinació i la maduresa personal de l’infant i està basat en el moviment i la percepció del ritme. Basant-me en el què diuen alguns autors i pedagogs s’han comprovat les hipòtesis a partir d’una investigació. Per poder investigar aquest fet s’han realitzat una sèrie d’observacions de diferents sessions de música amb infants de tres a set anys de dues escoles diferents. En una de les escoles, en la qual s’ha estat investigant, els alumnes fan música a partir del mètode Dalcroze i a l’altre escola no. A partir de les observacions de totes les sessions de música s’ha analitzat i comparat les dues maneres de treballar la música i les capacitats que es poden desenvolupar treballant la música d’una manera vivencial i dinàmica. Per fer la part pràctica s’ha utilitzant una metodologia qualitativa la qual investiga si a partir de la rítmica Dalcroze es poden estimular les diferents capacitats dels infants. Les dades han estat recollides en una graella d’observació on hi ha transcrita cada una de les sessions de música de les dues escoles, també han estat recollides a partir de les gravacions de totes les sessions i dues entrevistes realitzades a les professores de música. A partir d’aquí ha començat el procés d’investigació i anàlisi.

Épidémiologie et physiopathologie de la rétinopathie du prématuré [Epidemiology and pathophysiology of retinopathy of prematurity].

Retinopathy of prematurity (ROP) is a major cause of visual impairment in premature infants. It is characterized by an arrest in normal retinal vascular development associated with microvascular degeneration, followed by an abnormal hypoxiainduced neovascularization. Recent studies point out that ROP is a multifactorial disease, implicating both oxygen-dependent and oxygen-independent mechanisms. Oxygen-dependent factors leading to microvascular degeneration include generation of reactive oxygen species and suppression of specific oxygen-regulated vascular survival factors, such as vascular endothelial growth factor (VEGF) and erythropoietin. The other major mechanism for the initial capillary loss is oxygen-independent and implicates a deficit in growth factor IGF-1/IGFBP3. The proliferative, second phase of ROP is triggered by increases in vascular growth factors concentrations, in an attempt to compensate for the hypoxic retina. Novel signaling pathways for vascular repair, implicating both metabolite signaling and inflammatory lipids signaling, represent new therapeutic avenues for ROP.

Barnbyn Skå (Skå, la vila dels infants) 1947-1972: L’experiència terapèutica de Gustav Jonsson amb infants «irrecuperables»

The article presents the trajectory of the Swedish psychiatrist Gustav Jonsson (1907-1994) who, in the 1940s, revolutionised the therapeutic and educational treatment of children and young people, considered irreclaimable from the social point of view, who were committed to educational institutions. It analyses the social development of the Welfare State in Sweden, the legal framework of child protection, as well as the context of Swedish residential care centres for children and young people in the first half of the 20th century in order to go further into the psychological and educational work conducted with the Barnbyn Skå group. Jonsson redirected the analysis of violent behaviours that were manifest in these children and young people which made them intractable from the educational point of view and established elements of psychoanalytical understanding, based on a systemic approach in which the family context became essential in order to understand the children’s difficulties. Barnbyn Skå was the centre which, under the guidance of Jonsson, developed this new therapeutic and pedagogic approach. The educational work carried out there exceeded the traditional model in terms of control and surveillance. The methods were considered radical from within pedagogy and caused great controversy which led the centre to continuous investigations on behalf of the Social Services of Stockholm between 1960 and 1970. For several decades Barnbyn Skå has been considered a pioneering experience in the field of Scandinavian child psychiatry.

Tracheostomy in children.

We reviewed the records of 108 patients who had a tracheostomy performed over a 10-year period from July 1979 to April 1989. Median age at tracheostomy was 6 months (1 week-15 years). Indications for surgery were acquired subglottic stenosis (31.4%), bilateral vocal cord paralysis (22.2%), congenital airway malformations (22.2%) and tumours (11.1%). No epiglottis and no emergency situation had to be managed by tracheostomy. Operation was uneventful in all, but 8 patients (7.4%) developed a pneumothorax in the postoperative period. Twenty-one (19.5%) had severe complications during the cannulation period (tube obstruction in 11 patients with cardiorespiratory arrest in 4; dislocation of the tube in 6 patients). Fifteen patients (13.8%) had severe complications after decannulation (2 had a cardiorespiratory arrest); all 15 had to be recannulated. At the end of the study period 85 patients (78.7%) were successfully decannulated with a median period of tracheostomy of 486 days (8 days-6.6 years). The median hospital stay was 159 days (13 days-2.7 years). All patients could be discharged. Eight patients (7.4%) died but no death was related to tracheostomy. In summary the mortality rate is lower than reported in previous reviews and tracheostomy is a safe operation even in small children but cannula-related complications may lead to life-threatening events. The management of tracheostomized small children and infants in a highly staffed and monitored intensive care unit has allowed better handling of complications and has resulted in a reduction in cannula-related deaths.

La douleur prolongée chez le nouveau-né: étude de cas [Prolonged pain in neonates: retrospective analysis].

INTRODUCTION: infants hospitalised in neonatology are inevitably exposed to pain repeatedly. Premature infants are particularly vulnerable, because they are hypersensitive to pain and demonstrate diminished behavioural responses to pain. They are therefore at risk of developing short and long-term complications if pain remains untreated. CONTEXT: compared to acute pain, there is limited evidence in the literature on prolonged pain in infants. However, the prevalence is reported between 20 and 40 %. OBJECTIVE : this single case study aimed to identify the bio-contextual characteristics of neonates who experienced prolonged pain. METHODS : this study was carried out in the neonatal unit of a tertiary referral centre in Western Switzerland. A retrospective data analysis of seven infants' profile, who experienced prolonged pain ,was performed using five different data sources. RESULTS : the mean gestational age of the seven infants was 32weeks. The main diagnosis included prematurity and respiratory distress syndrome. The total observations (N=55) showed that the participants had in average 21.8 (SD 6.9) painful procedures that were estimated to be of moderate to severe intensity each day. Out of the 164 recorded pain scores (2.9 pain assessment/day/infant), 14.6 % confirmed acute pain. Out of those experiencing acute pain, analgesia was given in 16.6 % of them and 79.1 % received no analgesia. CONCLUSION: this study highlighted the difficulty in managing pain in neonates who are exposed to numerous painful procedures. Pain in this population remains underevaluated and as a result undertreated.Results of this study showed that nursing documentation related to pain assessment is not systematic.Regular assessment and documentation of acute and prolonged pain are recommended. This could be achieved with clear guidelines on the Assessment Intervention Reassessment (AIR) cyclewith validated measures adapted to neonates. The adequacy of pain assessment is a pre-requisite for appropriate pain relief in neonates.

The renal hemodynamic effects of Aspirin in newborn and young adult rabbits.

A group of neonatal (n=10) and 12-week-old (n=12) anesthetized, ventilated New Zealand white rabbits received an acute i.v. dose (40 mg/kg body weight) of acetylsalicylic acid (ASA, Aspirin). In the neonatal animals, i.v. ASA caused within 20 min a significant (P<0.01) fall in renal blood flow and glomerular filtration rate (GFR), with an equally significant (P<0.01) increase in filtration fraction and renal vascular resistance. The latter indicates greatly augmented renal vasconstriction or more precisely reduction in intrarenal vasodilatation by inhibition of vasodilatory prostaglandin (PG) synthesis. Urine volume decreased. The 12-week-old young adult animals responded in a similar, but significantly attenuated fashion. These experiments demonstrate that inhibition of PG synthesis in neonatal animals causes very rapid, reversible vasoconstriction, with a reduction in GFR. In addition, this study confirms previous observations that the renal hemodynamic response to the inhibition of PG synthesis is far more pronounced in neonatal animals than in (young) adult rabbits.

Escala d'Intensitat dels Suports per a Infants i Adolescents : resultados de la prueba piloto

La actual concepción de discapacidad intelectual, de acuerdo con la American Association on Intellectual and Developmental Disabilities (AAIDD), pone de manifiesto que la implementación de apoyos adecuados mejora el funcionamiento individual de las personas con discapacidad intelectual (DI). Con el fin de valorar las necesidades de apoyo que los niños y adolescentes con DI manifiestan en su vida cotidiana y, a partir de dicho conocimiento facilitar la elaboración de planes de apoyo individualizados, actualmente un grupo de trabajo internacional liderado por la propia AAIDD, entre los que se encuentra el grupo Discapacitat i Qualitat de Vida: Aspectes Educatius, está desarrollando la Supports Intensity Scale (SIS) for Children. El objetivo del presente artículo es dar a conocer el proceso de adaptación transcultural de la SIS for Children al contexto catalán, así como algunos resultados obtenidos en la prueba piloto que se ha llevado a cabo con una muestra de 33 niños y adolescentes de Cataluña, los cuales destacan la fiabilidad y validez del instrumento. Finalmente, el trabajo de validación de la escala actualmente en proceso, permitirá a los profesionales planificar y supervisar planes individualizados dirigidos a la promoción de experiencias de inclusión educativa y de integración a la comunidad.

Organ volume measurements: comparison between MRI and autopsy findings in infants following sudden unexpected death.

OBJECTIVE: To assess the accuracy of a semiautomated 3D volume reconstruction method for organ volume measurement by postmortem MRI. METHODS: This prospective study was approved by the institutional review board and the infants' parents gave their consent. Postmortem MRI was performed in 16 infants (1 month to 1 year of age) at 1.5 T within 48 h of their sudden death. Virtual organ volumes were estimated using the Myrian software. Real volumes were recorded at autopsy by water displacement. The agreement between virtual and real volumes was quantified following the Bland and Altman's method. RESULTS: There was a good agreement between virtual and real volumes for brain (mean difference: -0.03% (-13.6 to +7.1)), liver (+8.3% (-9.6 to +26.2)) and lungs (+5.5% (-26.6 to +37.6)). For kidneys, spleen and thymus, the MRI/autopsy volume ratio was close to 1 (kidney: 0.87±0.1; spleen: 0.99±0.17; thymus: 0.94±0.25), but with a less good agreement. For heart, the MRI/real volume ratio was 1.29±0.76, possibly due to the presence of residual blood within the heart. The virtual volumes of adrenal glands were significantly underestimated (p=0.04), possibly due to their very small size during the first year of life. The percentage of interobserver and intraobserver variation was lower or equal to 10%, but for thymus (15.9% and 12.6%, respectively) and adrenal glands (69% and 25.9%). CONCLUSIONS: Virtual volumetry may provide significant information concerning the macroscopic features of the main organs and help pathologists in sampling organs that are more likely to yield histological findings.

Pneumocystis-carinii-Pneumonie bei Säuglingen mit vertikaler HIV-Infektion in der Schweiz [Pneumocystis carinii pneumonia in infants with vertically acquired HIV infection in Switzerland]

OBJECTIVE: Review of incidence, clinical picture, therapy, and outcome of Pneumocystis carinii pneumonia (PCP) in infants with vertically-acquired HIV infection in Switzerland. METHODS: Inquiry among members of the Swiss Pediatrics AIDS Group, review of the data base of the Swiss Neonatal HIV Study and retrospective analysis of the charts from infants with PCP. RESULTS: Since 1986 PCP has been diagnosed in 10 out of 107 infants with vertically-acquired HIV infection. PCP occurred in 7 infants at the age of 3-6 months and in 3 at the age of 9-11 months. 4 infants showed symptoms related to HIV infection before developing PCP. Before the development of PCP, infection with HIV had been ascertained in 6 infants. In 2 the diagnosis was still unclear and in the 2 remaining the risk of HIV infection was not known. None of the infants was on primary prophylaxis against PCP. Signs and symptoms of PCP included cough and tachypnea (100%) as well as high fever up to 40 degrees C (90%). Transcutaneous oxygen saturation was 70-95%. Chest X-rays revealed interstitial infiltrates in 6 infants, localized infiltrates in 2 and interstitial as well as localized infiltrates in 2. The CD4+ cell count was, with one exception, < 1500/microliters, i.e. below the normal value for age. Side effects of high dose cotrimoxazole were noted in 6 patients. 5 infants required intubation and mechanical ventilation. 4 infants died due to PCP, including 3 of those who required intubation and mechanical ventilation. CONCLUSIONS: PCP in infants with vertically-acquired HIV infection preferentially occurs at the age of 3 to 6 months and is often lethal, especially in patients requiring intubation. Evaluation for HIV infection should be done as early as possible in order to introduce primary PCP prophylaxis in infants at risk for this opportunistic infection.

Impaired chemical coupling of cerebral blood flow is compatible with intact neurological outcome in neonates with perinatal risk factors.

Early detection of pathophysiological factors associated with permanent brain damage is a major issue in neonatal medicine. The aim of our study was to evaluate the significance of the CO2 reactivity of cerebral blood flow (CBF) in neonates with perinatal risk factors. Fourteen ventilated neonates with perinatal risk factors (pathological cardiotocogramm, low cord pH, postpartal encephalopathy) were enrolled into this prospective study. The study was performed 18-123 h after birth. CBF was measured using the noninvasive intravenous 133Xe method. Two measurements were taken with a minimal PaCO2-difference of 5 mm Hg. From the two CBF values the CO2 reactivity was calculated. Outcome was evaluated 1 year after birth. The CBF values at a lower PaCO2 ranged from 6.6 to 115. 2 ml/100 g brain issue/min (median = 18.2) and at a higher PaCO2 level from 7.1 to 125.7 ml/100 g brain tissue/min (median = 18.75). The calculated CO2 reactivity ranged from -9.6 to 6.6% (median 1.1%) change in CBF/mm Hg change in PaCO2. CO2 reactivity correlated with lowest pH (r2 = 0.35, p = 0.02). Two infants died, one of neonatal sepsis, the other of heart failure. Neurological outcome at the age of 1 year was normal in 11 patients, 1 had severe cerebral palsy. From the 12 surviving patients the patient with severe neurological deficit showed the highest CBF values (125.7 ml/100 g/min). Impaired chemical coupling of cerebral blood flow is compatible with intact neurological outcome in neonates with perinatal risk factors. CO2 reactivity in these newborns correlates with the lowest pH and may reflect the severity of perinatal asphyxia.

Pulse oximetry and transcutaneous oxygen tension for detection of hypoxemia in critically ill infants and children.

We tested the performance of transcutaneous oxygen monitoring (TcPO2) and pulse oximetry (tcSaO2) in detecting hypoxia in critically ill neonatal and pediatric patients. In 54 patients (178 data sets) with a mean age of 2.4 years (range 1 to 19 years), arterial saturation (SaO2) ranged from 9.5 to 100%, and arterial oxygen tension (PaO2) from 16.4 to 128 mmHg. Linear correlation analysis of pulse oximetry vs measured SaO2 revealed an r value of 0.95 (p less than 0.001) with an equation of y = 21.1 + 0.749x, while PaO2 vs tcPO2 showed a correlation coefficient of r = 0.95 (p less than 0.001) with an equation of y = -1.04 + 0.876x. The mean difference between measured SaO2 and tcSaO2 was -2.74 +/- 7.69% (range +14 to - 29%) and the mean difference between PaO2 and tcPO2 was +7.43 +/- 8.57 mmHg (range -14 to +49 mmHg). Pulse oximetry was reliable at values above 65%, but was inaccurate and overestimated the arterial SaO2 at lower values. TcPO2 tended to underestimate the arterial value with increasing PaO2. Pulse oximetry had the best sensitivity to specificity ratio for hypoxia between 65 and 90% SaO2; for tcPO2 the best results were obtained between 35 and 55 mmHg PaO2.

Effect of maternal clinical chorioamnionitis on neonatal morbidity in very-low birthweight infants: a case control study

Aims: To assess the relationship between maternal clinical chorioamnionitis and neonatal outcome in preterm very-low birthweight (VLBW) infants. Methods: An observational case-control study was conducted in the Neonatology Services of 12 acute-care teaching hospitals in Spain. Between January 2004 and December 2006, all consecutive VLBW (F1500 g) infants born to a mother with clinical chorioamnionitis were enrolled. Controls were infants without chorioamnionitis matched by gestational age who were born immediately after each index case. Results: There were 165 cases and 163 controls. A significantly higher percentage of cases than controls required intubation (53% vs. 35.8%), had normal intrauterine growth (98.1% vs. 84.7%), were born in a tertiary center (inborn) (95.1% vs. 89.1%), from single gestations (76.4% vs. 65.6%) and vaginal delivery (47.3% vs. 33.3%), showed a lowerApgar score at 5 min, and presented a higher rate of earlyonset sepsis (10.4% vs. 1.2%). Older maternal age (32.5 vs. 30.8 years), premature labor (67.3% vs. 25.8%), premature rupture of membranes (61.3% vs. 25.8%), and antibiotic treatment (88.5% vs. 52.3%) were significantly more frequent among cases than controls. Conclusions: After controlling by gestational age, maternal chorioamnionitis was associated with neonatal depression and early sepsis but not with other prematurity-related complications.

Risk of hypoglycemia in newborns from mothers with gestacional diabetes

There are not enough previous publications which are focused on mothers withwell-controlled gestational diabetes mellitus (GDM) as a risk factor that determines the occurrence of neonatal hypoglycemia. In addition, approaches to blood glucose monitoring have been inconsistent and poorly defined. Our objective is to determine if being a newborn from a mother with well-controlled gestational diabetes (regardless insulin treatment) have a higher risk to develop hypoglycemia than a healthy newborn, using a defined and strict protocol. The project will take place in a regional hospital of Girona. We will recruit from 2014 to 2015 a cohort of 623 infants born in this center without any malformation or any perinatal pathology or complication, selected with a consecutive sampling. We will record sex, ethnicity and gestational age information. We will measure blood glucose levels and anthropometric measurements in newborns always taking into account the presence of well-controlled maternal gestational diabetes or not. Patients will be followed up during 24 hours to determine the incidence of hypoglycemia. We will analyze the contribution between exposure factors that we have studied and the incidence of the outcome using a multivariate analysis
