Achados endoscópicos em crianças com estridor

Doenças congênitas e adquiridas das vias aéreas podem causar dispnéia e estridor em crianças. Nas UTIs tem-se registrado maior sobrevida de prematuros, porém também elevada incidência de complicações relacionadas à intubação. OBJETIVO: Analisar retrospectivamente os achados endoscópicos em crianças com estridor. TIPO DE ESTUDO: Corte transversal. MATERIAL E MÉTODOS: Foram revisados 55 prontuários de crianças com estridor, submetidas aos exames endoscópicos de janeiro de 1997 a dezembro de 2003. Endoscopias foram: estridor pós-extubação (63,63%) e avaliação de estridor neonatal (21,82%). Observou-se alto índice de doenças associadas, como pulmonares (60%), neurológicas (45,4%) e DRGE (40%). Os principais achados endoscópicos e as indicações de traqueotomia foram: estenose subglótica (27,27%) e processos inflamatórios das vias aéreas (21,82%), principalmente em crianças com menos de cinco anos. Lesões congênitas foram mais freqüentes em crianças com menos de um ano. CONCLUSÕES: O estridor na infância possui múltiplas etiologias, sendo as relacionadas à intubação traqueal as mais freqüentes em hospitais com atendimento de doenças complexas. Pediatras e otorrinolaringologistas devem conhecer as causas de estridor, realizando avaliação clínica detalhada para determinar a gravidade do caso. O exame endoscópico deverá ser minucioso e detalhado.

Fungemia by yeasts in Brazil: occurrence and phenotypic study of strains isolated at the Public Hospital, Botucatu, São Paulo

Objective. - In this study strains of yeasts isolated from the blood of human patients were analyzed taxonomically, their virulence factors were determined and compared, and phenotypic markers were used to compare the samples with respect to phenotypic differences across the range of patients as well as between samples isotated from the same patient.Methods. - the study involved a total of 75 strains of yeast isolated from the blood of in-patients of the Public Hospital, Botucatu, S (a) over tildeo Paulo, Brazil, with a clinical profile of fungemia. The hospital wards with the largest number of fungemias were neonatal intensive care units (ICUs) (32%) followed by gastric surgery (13.4%) and pediatric wards (10.7%). After identification, the samples were analyzed for the production of phospholipase and proteinase enzymes, and biotyped according to their susceptibility to killer toxins.Results. - the most frequent species found was Candida albicans (38.7%) followed by C. parapsilosis (30.7%). In terms of enzyme production, 98.7% of the 75 samples of yeast presented a strongly positive activity for proteinase; however, 78.7% did not present any phospholipasic activity. Six different biotypes were identified, the most frequent being 511 and 888.Conclusion. In association with phenotypic methods, genetic analyses should also be made of the samples under study to help in the rational development of a wider range of preventive measures and better control of hospital-contracted infections.

Sepsis and Neutropenia in Very Low Birth Weight Infants Delivered of Mothers with Preeclampsia

Objective To study the association between maternal preeclampsia and neonatal sepsis in very low birth weight newborns.Study design We studied all infants with birth weights between 500 g and 1500 g who were admitted to 6 neonatal intensive care units of the Brazilian Network on Neonatal Research for 2 years. Exclusion criteria were major malformations, death in the delivery room, and maternal chronic hypertension. Absolute neutrophil count was performed in the first 72 hours of life.Results A total of 911 very low birth weight infants (preeclampsia, 308; non-preeclampsia, 603) were included. The preeclampsia group had significantly higher gestational age, more cesarean deliveries, antenatal steroid, central catheters, total parenteral nutrition, and neutropenia, and less rupture of membranes >18 hours and mechanical ventilation. Both groups had similar incidences of early sepsis (4.6% and 4.2% in preeclampsia and non-preeclampsia groups, respectively) and late sepsis (24% and 22.1% in preeclampsia and non-preeclampsia groups, respectively). Vaginal delivery and neutropenia were associated with multiple logistic regressions with early sepsis, and mechanical ventilation, central catheter, and total parenteral nutrition were associated with late sepsis. Death was associated with neutropenia in very preterm infants.Conclusions Preeclampsia did not increase neonatal sepsis in very low birth weight infants, and death was associated with neutropenia in very preterm infants.

Acute and sustained effects of early administration of inhaled nitric oxide to children with acute respiratory distress syndrome

OBJECTIVE: To determine the acute and sustained effects of early inhaled nitric oxide on some oxygenation indexes and ventilator settings and to compare inhaled nitric oxide administration and conventional therapy on mortality rate, length of stay in intensive care, and duration of mechanical ventilation in children with acute respiratory distress syndrome. DESIGN: Observational study. SETTING: Pediatric intensive care unit at a university-affiliated hospital. PATIENTS: Children with acute respiratory distress syndrome, aged between 1 month and 12 yrs. INTERVENTIONS: Two groups were studied: an inhaled nitric oxide group (iNOG, n = 18) composed of patients prospectively enrolled from November 2000 to November 2002, and a conventional therapy group (CTG, n = 21) consisting of historical control patients admitted from August 1998 to August 2000. MEASUREMENTS AND MAIN RESULTS: Therapy with inhaled nitric oxide was introduced as early as 1.5 hrs after acute respiratory distress syndrome diagnosis with acute improvements in Pao(2)/Fio(2) ratio (83.7%) and oxygenation index (46.7%). Study groups were of similar ages, gender, primary diagnoses, pediatric risk of mortality score, and mean airway pressure. Pao(2)/Fio(2) ratio was lower (CTG, 116.9 +/- 34.5; iNOG, 62.5 +/- 12.8, p <.0001) and oxygenation index higher (CTG, 15.2 [range, 7.2-32.2]; iNOG, 24.3 [range, 16.3-70.4], p <.0001) in the iNOG. Prolonged treatment was associated with improved oxygenation, so that Fio(2) and peak inspiratory pressure could be quickly and significantly reduced. Mortality rate for inhaled nitric oxide-patients was lower (CTG, ten of 21, 47.6%; iNOG, three of 18, 16.6%, p <.001). There was no difference in intensive care stay (CTG, 10 days [range, 2-49]; iNOG, 12 [range, 6-26], p >.05) or duration of mechanical ventilation (TCG, 9 days [range, 2-47]; iNOG, 10 [range, 4-25], p >.05). CONCLUSIONS: Early treatment with inhaled nitric oxide causes acute and sustained improvement in oxygenation, with earlier reduction of ventilator settings, which might contribute to reduce the mortality rate in children with acute respiratory distress syndrome. Length of stay in intensive care and duration of mechanical ventilation are not changed. Prospective trials of inhaled nitric oxide early in the setting of acute lung injury in children are needed.

Late-onset sepsis: Epidemiology, evaluation, and outcome

Late-onset neonatal sepsis is a common serious problem in preterm infants in neonatal intensive care units. Diagnosis can be difficult because clinical manifestations are not specific and none of the available laboratory tests can be considered an ideal marker. For this reason, a combination of markers has been proposed. Complete blood count and acute-phase reactants evaluated together help in diagnosis. C-reactive protein is a specific but late marker, and procalcitonin has proven accurate, although it is little studied in newborns. Blood, cerebrospinal fluid, and urine cultures always should be obtained when late-onset sepsis is suspected. Blood culture, the gold standard in diagnosis, is highly sensitive but needs up to 48 hours to detect microbial growth. Various cytokines have been investigated as early markers of infection, but results are not uniform. Other diagnostic tests that offer promise include: neutrophil surface markers, granulocyte colony-stimulating factor, toll-like receptors, and nuclear factor kappa B. The greatest hope for quick and accurate diagnosis lies in molecular biology, using real time polymerase chain reaction combined withDNAmicroarray. Sepsis and meningitis may affect both the short- and long-term prognosis for newborns. Mortality in neonatal meningitis has been reduced in recent years, but short-term complications and later neurocognitive sequelae remain. Late-onset sepsis significantly increases preterm infant mortality and the risk of cerebral lesions and neurosensory sequelae, including developmental difficulties and cerebral palsy. Early diagnosis of late-onset sepsis contributes to improved neonatal prognosis, but the outcome remains far from satisfactory. © 2010 by the American Academy of Pediatrics.

Red blood cell transfusions in the neonate

Despite recent trends to decrease allogeneic red blood cell (RBC) transfusion thresholds, such transfusions remain an important supportive and life-saving intervention for neonatal intensive care patients. In neonates, apart from concerns about transfusionassociated infections, many controversial questions regarding transfusion practices remain unanswered. Moreover, neonates present specific clinical and immunologic characteristics that require selected blood component products. This article addresses many of these issues from a medical perspective, with emphasis on the best blood banking techniques to provide RBC products for neonatal transfusions.

O impacto do Método Mãe Canguru no processo de aprendizagem de prematuros de baixo peso: Revisão da literatura

Technology advances and scientific studies in Neonatal Intensive Care Units (NICU) have contributed significantly to reduce mortality and morbidity of at-risk newborns (NB). However, they are more likely to present neurological and/or developmental psychomotor delay with neurological and sensory alterations. Therefore, proposals for neonatal intervention were developed with the aim of protecting the baby and offering appropriate incentives to minimize the effects of hospital intervention. To this end, programs of protective measures such as the Kangaroo Mother Care (KMC) were developed. Given the relevance of the issue described, this systematic review critically appraises articles from the national and international literature, published in recent years (from 2000 to 2011), that describe whether the KMC can be a protective factor for the development of writing in premature infants. The textual search was conducted using the Virtual Health Library (VHL), a website that covers publications worldwide, allowing access to articles from health science, including LILACS, IBECS, MEDLINE, Cochrane Library and SciELO, as database. The findings revealed that infants who participated in the KMC program showed improvements in their development and that factors such as low-birth-weight prematurity and learning disorders have close relationship with the onset of motor impairments and changes in psychomotor development. The findings showed no articles describing the KMC as a protective factor for the incidence of dysgraphia. Thus, we emphasize the importance of conducting further studies on these topics.

Avaliação dos custos da assistência de recém-nascidos de mães hipertensas no Hospital das Clínicas - UNESP - Botucatu

The Hypertension Arterial Gestationis is a of largest complications to the pregnant women, a time that is associated with to high risk of morbimortalidade fetal and maternal ;the term If referred the levels pressure equal or above of 140mmhg to the pressure systolic and of 90mmhg to the pressure diastolic (1).Hypertension in pregnancy can be classified into gestational hypertension, chronic hypertension, preeclampsia and eclampsia(3). This study aimed to calculate and analyze the cost of care of newborns of hypertensive mothers hospitalized in rooming, nursery and the neonatal intensive care unit (Neonatal UTI). It’s a study of exploratory, descriptive and quantitative data analysis, in newborns of mothers with hypertension, who underwent prenatal care in HCFMB, from January 1 to 31 in December 2010. The data analysis showed that the cost of care for newborn in rooming was R$ 38.62 for the control group and groups of hypertensive mothers were R$ 19.93 to R$ 37.38. The costs of care to the newborn in the nursery were R$ 1,781.81 for the control group and groups of hypertensive mothers were R$ 680.03 to 7544.10. The costs for the newborn who Neonatal UTI were R$ 7,468.60 for the control group and groups of hypertensive mothers were R$ 5,228.02 to R $ 18,372.75. The total costs of care for newborn in rooming, nursery and Neonatal UTI were R$ 916.15 for the control group, R$ 1,385.98 for the HAC group, R$ 327.23 for the group HAS, R$ 3,896.57 for the group of preeclampsia and R$ 6,326.54 for the group of eclampsia. Considerations It can be concluded that the costs of mothers with preeclampsia and eclampsia were higher, being conditions with increased risk of maternal-fetal morbidity / mortality, requiring care in intensive care unit and longer stay in hospital

Painful procedures and analgesia in the NICU: what has changed in the medical perception and practice in a ten-year period?

To compare the use of analgesia versus neonatologists' perception regarding analgesic use in painful procedures in the years 2001, 2006, and 2011. This was a prospective cohort study of all newborns admitted to four university neonatal intensive care units (NICUs) during one month in 2001, 2006, and 2011. The frequency of analgesic prescription for painful procedures was evaluated. Of the 202 neonatologists, 188 answered a questionnaire giving their opinion on the intensity of pain during lumbar puncture (LP), tracheal intubation, mechanical ventilation (MV), and postoperative period (PO) using a 10-cm visual analogic scale (VAS; pain >3cm). For LP, 12% (2001), 43% (2006), and 36% (2011) were performed using analgesia. Among the neonatologists, 40-50% reported VAS >3 for LP in all study periods. For intubation, 30% received analgesia in the study periods, and 35% (2001), 55% (2006), and 73% (2011) of the neonatologists reported VAS >3 and would prescribe analgesia for this procedure. As for MV, 45% (2001), 64% (2006), and 48% (2011) of patient-days were under analgesia; 56% (2001), 57% (2006), and 26% (2011) of neonatologists reported VAS >3 and said they would use analgesia during MV. For the first three PO days, 37% (2001), 78% (2006), and 89% (2011) of the patients received analgesia and more than 90% of neonatologists reported VAS >3 for major surgeries. Despite an increase in the medical perception of neonatal pain and in analgesic use during painful procedures, the gap between clinical practice and neonatologist perception of analgesia need did not change during the ten-year period.

Characterization of the motor performance in infants with a diagnosis of Cerebral Palsy in process of rehabilitation: the importance of the proactivity of caregivers

Introduction: The progress in technology, associated to the high survival rate in premature newborn infants in neonatal intensive care units, causes an increase in morbidity. Individuals with CP present complex motor alterations, with primary deficits of abnormal muscle tone affecting posture and voluntary movement, alteration of balance and coordination, decrease of force, and loss of selective motor control with secondary problems of contractures and bone deformities. Objective: The aim of this work is to describe the spontaneous movement and strategies that lead infants with cerebral palsy to move. Methods: Seven infants used to receive assistance at the Essential Stimulation Center of CIAM (Israeli Center for Multidisciplinary Support - Philanthropic Institution), with ages ranging between six and 18 months with diagnosis of Cerebral Palsy (CP) were assessed. Results: The results show the difficulty presented by the infants with respect to the spontaneous motor functions and the necessity of help from the caregiver in order to perform the functional activity (mobility). Prematurity prevails as the major risk factor among the complications. Conclusion: The child development can be understood as a product of the dynamic interactions involving the infant, the family, and the context. Thus, the social interactions and family environment in which the infant live may encourage or limit both the acquisition of skills and the functional independence.

Low Apgar scores at 5 minutes in a low risk population: maternal and obstetrical factors and postnatal outcome

Objective: To evaluate the association between Apgar scores of less than seven at five minutes (AS(5min) < 7) and antenatal factors and postnatal outcomes. Methods: A retrospective cohort and case-control study of 27,252 consecutive term newborns in a low risk obstetrical population between January 2003 and December 2010. Maternal and infant databases were reviewed from all cases with AS(5min) < 7 (n = 121; 0.4%) and 363 cases with AS(5min) >= 7 at 5 minutes who were randomly selected by a computer program. The main outcomes were neonatal death, newborn respiratory distress, need for orotracheal intubation and neonatal intensive care unit (NICU), and hypoxic-ischemic-encephalopathy. Results: After multiple regression analysis, repeated late decelerations on cardiotocography (OR: 2.4; 95% CI: 1.4-4.1) and prolonged second stage of labor (OR: 3.3; 95% CI: 1.3-8.3) were associated with AS(5min) < 7, as well as neonatal respiratory distress (OR: 3.0; 95% CI: 1.3-6.9), orotracheal intubation (OR: 2.5; 95% CI: 1.2-4.8), need for NICU (OR: 9.5; 95% CI: 6.7-16.8), and hypoxic-ischemic-encephalopathy (OR: 14.1; 95% CI: 3.6-54.7). No other antenatal factors were associated with AS(5min) < 7 (p > 0.05). Conclusion: Repeated late decelerations and prolonged second stage of labor in the low-risk population are predictors of AS(5min) < 7, a situation associated with increased risk of neonatal respiratory distress, need for mechanical ventilatory support and NICU, and hypoxic-ischemic-encephalopathy.
