Sleep quantity and quality of critically ill children perceived by caregivers and bedside nursing staff: a pilot study.

STUDY OBJECTIVES: Sleep is crucial for healing but often impaired in the pediatric intensive care unit due to environmental disruptions. Caregivers and bedside nursing staff are often most aware of these factors and the impact on patient sleep, but studies have not yet compared their perceptions. METHODS: Caregivers and bedside nursing staff of pediatric patients staying a second night in the pediatric intensive care unit were asked to complete a survey regarding environmental factors (ie, temperature, light, sound, nursing staff room entries), sleep quality, and sleep quantity (ie, sleep duration, number of naps) of the pediatric patient. Caregivers were asked similar questions about their child's sleep at home. RESULTS: The caregivers and nursing staff of 31 pediatric patients participated in this pilot study. There was no significant difference between caregiver and nursing staff ratings of sleep quality, sleep duration, number of naps, room temperature, sound, or light (P > .05 for all). Nursing staff did report significantly more room entries than caregivers (P = .01). Compared to sleep at home, caregivers reported sleep in the hospital to be of lower quality (P = .009) with more frequent room entries (P = .01). CONCLUSIONS: Caregivers rate their child's sleep in the pediatric intensive care unit as lower quality than sleep at home. Caregivers and bedside nursing staff largely agree about pediatric patient sleep quality and quantity as well as environmental factors. This agreement may facilitate further research and interventions at improving sleep in the pediatric intensive care unit. CITATION: Witte MA, Lloyd RM, McGree M, Kawai Y.

Caring for Critically Ill Children With the ICU Liberation Bundle (ABCDEF): Results of the Pediatric Collaborative.

OBJECTIVES: Assess clinical outcomes following PICU Liberation ABCDEF Bundle utilization. DESIGN: Prospective, multicenter, cohort study. SETTING: Eight academic PICUs. PATIENTS: Children greater than 2 months with expected PICU stay greater than 2 days and need for mechanical ventilation (MV). INTERVENTIONS: ABCDEF Bundle implementation. MEASUREMENT AND MAIN RESULTS: Over an 11-month period (3-mo baseline, 8-mo implementation), Bundle utilization was measured for 622 patients totaling 5,017 PICU days. Risk of mortality was quantified for 532 patients (4,275 PICU days) for correlation between Bundle utilization and MV duration, PICU length of stay (LOS), delirium incidence, and mortality. Utilization was analyzed as subject-specific (entire PICU stay) and day-specific (single PICU day). Median overall subject-specific utilization increased from 50% during the 3-month baseline to 63.9% during the last four implementation months ( p < 0.001). Subject-specific utilization for elements A and C did not change; utilization improved for B (0-12.5%; p = 0.007), D (22.2-61.1%; p < 0.001), E (17.7-50%; p = 0.003), and F (50-79.2%; p = 0.001). We observed no association between Bundle utilization and MV duration, PICU LOS, or delirium incidence. In contrast, on adjusted analysis, every 10% increase in subject-specific utilization correlated with mortality odds ratio (OR) reduction of 34%, p < 0.001; every 10% increase in day-specific utilization correlated with a mortality OR reduction of 1.4% ( p = 0.006). CONCLUSIONS: ABCDEF Bundle is applicable to children. Although enhanced Bundle utilization correlated with decreased mortality, increased utilization did not correlate with duration of MV, PICU LOS, or delirium incidence. Additional research in the domains of comparative effectiveness, implementation science, and human factors engineering is required to understand this clinical inconsistency and optimize PICU Liberation concept integration into clinical practice.

Improving Mobility Practices of Critically Ill Children.

INTRODUCTION: This quality improvement project aimed to improve mobility practices in a pediatric intensive care unit. METHOD: Three interventions were implemented: a staff-developed mobility progression guideline (including patient mobility phase identification using animal images), physical therapy (PT), and occupational therapy (OT) referrals for all patients with expected hospitalizations of more than 3 days, and the use of activity goal posters. The frequency of mobility activities performed, the number of PT and OT referrals and nurses' confidence in mobilizing patients were compared before and after project implementation. RESULTS: Improvements occurred in the median number of daily mobility activities per patient encounter (1.5-4.0), number of PT and OT referrals (43% and 61% increase, respectively), and nurses' confidence in mobilizing patients (69% of clinical nurses agreed their confidence in mobilizing patients improved after protocol implementation). DISCUSSION: Implementation of an interprofessional mobility quality improvement project improved mobility practices in the pediatric intensive care unit.

Suppression of axillary odor and control of axillary bacterial flora by erythritol.

BACKGROUND: Erythritol is a sugar alcohol with 4 carbon atoms that has approximately 75% of the sweetness of sucrose. It is a safe and widely used food component. AIMS: We herein investigated the growth inhibitory effects on axillary odor-causing bacteria and axillary odor-reducing effects of erythritol. METHODS: Growth tests in vitro were performed on Corynebacterium minutissimum, C. striatum, and Staphylococcus epidermidis. An axillary odor sensory test and axillary bacterial flora analysis were then conducted. A test product containing erythritol was applied to the axillae of 18 subjects. RESULTS: Erythritol significantly inhibited the growth of tested bacteria. The results of the axillary odor sensory test showed that the median values for each odor intensity of Total axillary odor intensity, Animal, Milk-fat, Damp-dried dust cloth, and Sourness were significantly lower in the test product application group than in the placebo group (p = 0, 0.008, 0.025, 0.004, 0, 0.001, respectively). The axillary flora analysis revealed that the relative abundance of the most dominant bacteria was lower in the test product application group than in the placebo group. Furthermore, the diversity of the total bacterial flora was significantly higher in the test product application group (p = 0.048). CONCLUSION: The present results suggest that erythritol inhibits the growth of the predominant bacteria in the axilla, increases the diversity of the bacterial flora, controls the bacterial flora of the skin to a healthy abundance ratio, and reduces axillary odor.

Patterns of Delirium in a Pediatric Intensive Care Unit and Associations With Noise Pollution.

Objective: Delirium is a common problem in the Pediatric Intensive Care Unit (PICU) and is associated with increased length of stay, cost and mortality. This study evaluated the relationship between noise pollution and delirium risk. Design: This is a Quality Improvement (QI) initiative at an academic PICU. Sound levels were monitored and patients were screened for delirium using the Cornell Assessment of Pediatric Delirium (CAPD). Setting PICU Patients: All PICU patients Interventions: None Measurements and Main Results: Over the 83-week study period (2015-2017), the median [IQR] CAPD score was 8 [3 to 14]. Nursing compliance with the CAPD was 72.2%. The proportion of patients screening positive for delirium (CAPD ≥ 9) was 45.9%. A total of 329 711 hly decibel (dB) measurements were collected and reported. Occupied rooms were louder than unoccupied rooms (51.8 [51.6-51.9] dB vs. 49.8 [49.7-49.9] dB, respectively, p < 0.001). Days (10 AM to 4 PM) were louder than nights (11 PM to 5 AM) (52.8 [52.7-53.0] dB vs. 50.7 [49.9-51.5] dB, respectively p < 0.001) in occupied rooms. Winter (Nov-Feb) months were louder than summer (May-Aug) months (52.0 [51.8-52.3] dB vs. 51.5 [51.3-51.7] dB, respectively, p < 0.002) in occupied rooms. Median weekly nighttime noise levels and CAPD scores demonstrated a correlation coefficient of 0.6 (p < 0.001). Median weekly risk of mortality (ROM) and CAPD scores demonstrated a correlation coefficient of 0.15 (p < 0.01). Conclusions: Significant noise pollution exists in the PICU with a moderate correlation between nighttime noise levels and CAPD scores. This could potentially implicate noise pollution as a risk factor for the development of delirium.

[Surgical Treatment for Giant Coronary Aneurysm Complicated by Acute Myocardial Infarction and Cardiopulmonary Arrest:Report of a Case].

Giant coronary aneurysm is rare, but a life-threatening disease. We report a 67-year-old man with 39 mm coronary aneurysm. He was presented to our facility with acute coronary syndrome complicated by cardiogenic shock. Angiography demonstrated giant coronary aneurysm and occlusion of the right coronary artery. After cardiopulmonary resuscitation and cardiopulmonary support (PCPS), emergent excision of aneurysm and coronary artery bypass grafting was performed. The postoperative course was good without complications. Most giant coronary artery aneurysms are asymptomatic but some patients present with angina pectoris, sudden death, fistula formation, pericardial tamponade, compression of surrounding structures, or congestive heart failure. But once complications, such as thrombosis, distal embolization, fistula formation or rupture occurred, it is difficult to save life without aggressive surgery. At present, there are no specific guidelines for the treatment of giant coronary aneurysm. Surgical correction is a preferred approach for the treatment of giant coronary artery aneurysms.

Improving Pediatric Delirium Assessment Documentation and Implementation of a Nonpharmacologic Delirium Management Bundle in the Cardiovascular Intensive Care Unit.

BACKGROUND: Pediatric delirium is common, associated with negative patient outcomes, and infrequently assessed in the ICU. Locally, pediatric delirium assessments in the cardiac PICU were infrequently documented resulting in an initiative to increase assessment documentation and implement a nurse-driven management protocol, the Bundle to Eliminate Delirium (BED). METHODS: This was a nurse-driven, quality improvement project in an eleven-bed cardiac PICU at a large academic health care facility. A pre- and postimplementation survey evaluating delirium management perceptions, knowledge, and assessment barriers was emailed to 113 nurses. Nurses received education about general delirium principles and assessment followed by weekly emails that included delirium assessment documentation rates and targeted education. Subsequently, BED education was provided via email followed by BED implementation, inclusion of BED completion rates in weekly emails, and observational audits of BED implementation. FINDINGS: 1522 delirium assessment opportunities were evaluated. Assessment documentation increased by 33%. Nurses reported greater confidence in their ability to manage delirium (P < .05 for numerous aspects of delirium care) and were less likely to report 'positive delirium assessments not acted upon' as a barrier to delirium assessment. BED implementation was inconsistent. DISCUSSION: Nursing education and feedback can increase delirium assessment rates and confidence in management but the impact of BED on these outcomes is not clear. APPLICATION TO PRACTICE: Improvement in pediatric delirium care may be obtained through a nurse-driven quality improvement project but an interprofessional approach is needed for optimal management. More studies are needed to identify effective pediatric delirium management strategies such as the BED.

Prediction of age and brachial-ankle pulse-wave velocity using ultra-wide-field pseudo-color images by deep learning.

This study examined whether age and brachial-ankle pulse-wave velocity (baPWV) can be predicted with ultra-wide-field pseudo-color (UWPC) images using deep learning (DL). We examined 170 UWPC images of both eyes of 85 participants (40 men and 45 women, mean age: 57.5 ± 20.9 years). Three types of images were included (total, central, and peripheral) and analyzed by k-fold cross-validation (k = 5) using Visual Geometry Group-16. After bias was eliminated using the generalized linear mixed model, the standard regression coefficients (SRCs) between actual age and baPWV and predicted age and baPWV from the UWPC images by the neural network were calculated, and the prediction accuracies of the DL model for age and baPWV were examined. The SRC between actual age and predicted age by the neural network was 0.833 for all images, 0.818 for central images, and 0.649 for peripheral images (all P < 0.001) and between the actual baPWV and the predicted baPWV was 0.390 for total images, 0.419 for central images, and 0.312 for peripheral images (all P < 0.001). These results show the potential prediction capability of DL for age and vascular aging and could be useful for disease prevention and early treatment.

Transcriptional profiling of lactic acid treated reconstructed human epidermis reveals pathways underlying stinging and itch.

The incidence of sensitive skin with stinging and itch following chemical exposure in products such as cosmetics is increasing, but molecular mechanisms underlying this pathophysiology remain understudied. Here we performed transcriptional analysis of reconstructed human epidermis (RHE) 1, 6, and 24 h following topical lactic acid (LA) application, a known inducer of the sensitive skin reaction. Since little is known about the specific role of keratinocyte transcriptional changes in mediating stinging and itch, we performed pathway analysis using several publically available databases and then focused on significantly changed transcripts involved in stress responses and itch signaling using the Comparative Toxicogenomics Database. LA treatment induced damage-associated genes HSPA1A, DDIT3, IL1A, and HMGB2. Neurotrophic factors including BDNF, ARTN, PGE2, and chemokines were also upregulated. Stimulation of the RHE with 5% LA did not reduce cell viability, but reduced the trans-epidermal electric resistance, suggesting barrier dysfunction. Accordingly, skin barrier formation genes such as filaggrins (FLG, FLG2) and corneodesmosin (CDSN) were downregulated. To our knowledge, this is the first study focusing on transcriptional changes underlying the stinging response of keratinocytes upon LA stimulation. While follow-up research is needed, this study provides new insight into the mechanisms underlying the sensitive skin reaction.

Quality Improvement Initiative to Reduce Pediatric Intensive Care Unit Noise Pollution With the Use of a Pediatric Delirium Bundle.

OBJECTIVES:: Noise pollution in pediatric intensive care units (PICU) contributes to poor sleep and may increase risk of developing delirium. The Environmental Protection Agency (EPA) recommends <45 decibels (dB) in hospital environments. The objectives are to assess the degree of PICU noise pollution, to develop a delirium bundle targeted at reducing noise, and to assess the effect of the bundle on nocturnal noise pollution. METHODS:: This is a QI initiative at an academic PICU. Thirty-five sound sensors were installed in patient bed spaces, hallways, and common areas. The pediatric delirium bundle was implemented in 8 pilot patients (40 patient ICU days) while 108 non-pilot patients received usual care over a 28-day period. RESULTS:: A total of 20,609 hourly dB readings were collected. Hourly minimum, average, and maximum dB of all occupied bed spaces demonstrated medians [interquartile range] of 48.0 [39.0-53.0], 52.8 [48.1-56.2] and 67.0 [63.5-70.5] dB, respectively. Bed spaces were louder during the day (10AM to 4PM) than at night (11PM to 5AM) (53.5 [49.0-56.8] vs. 51.3 [46.0-55.3] dB, P < 0.01). Pilot patient rooms were significantly quieter than non-pilot patient rooms at night (n=210, 45.3 [39.7-55.9]) vs. n=1841, 51.2 [46.9-54.8] dB, P < 0.01). The pilot rooms compliant with the bundle had the lowest hourly nighttime average dB (44.1 [38.5-55.5]). CONCLUSIONS:: Substantial noise pollution exists in our PICU, and utilizing the pediatric delirium bundle led to a significant noise reduction that can be perceived as half the loudness with hourly nighttime average dB meeting the EPA standards when compliant with the bundle.

The Role of Saline and Sodium Bicarbonate Preprocedural Hydration to Prevent Mid-term Renal Insufficiency in Patients with Chronic Kidney Disease Undergoing Percutaneous Coronary Intervention.

Objective Persistent renal damage (RD) three months after exposure to contrast media is associated with contrast-induced acute kidney injury (CI-AKI) and poor clinical outcomes. Little is known about the role of preprocedural hydration on persistent RD in patients with chronic kidney disease [CKD; estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2] undergoing percutaneous coronary intervention (PCI). We therefore examined the use of preprocedural hydration to decrease the incidence of persistent RD. Methods Between 2012 and 2015, 1,230 consecutive patients undergoing PCI, except for patients with an eGFR ≥60 mL/min/1.73 m2, on dialysis, having acute myocardial infarction, or recently having started renin-angiotensin inhibitors, were screened (n=333). Before their index PCI, the 12-h saline group (n=103) received 1 mL/kg/h 0.9% sodium chloride for 12 hours, and the 1-h bicarbonate group (n=63) received 3 mL/kg 154 mEq/L sodium bicarbonate for 1 hour. The control group (n=167) received no pre-procedural hydration. The study outcome of kidney function decline was investigated using the percent-change (%-change) of the calculated creatinine clearance between the baseline value and the lowest value recorded three to six months after index PCI. Results There was less renal function deterioration in the saline group than in the control group, and the bicarbonate group showed deterioration similar to the other groups (%-change; 12-h saline 2.0±11.3% vs. control -5.6±12.6%, p<0.001; vs. 1-h bicarbonate -1.8±14.1%, p=0.18; 1-h bicarbonate vs. control, p=0.14 ANOVA). A multiple regression analysis adjusted for risk factors for persistent RD showed that saline hydration correlated independently with a higher %-change (r=0.262, p<0.001). Conclusion Preprocedural 12-h saline may be better than no preprocedural hydration in preventing mid-term renal insufficiency in CKD patients undergoing PCI.

Right ventricular enlargement predicts responsiveness to tolvaptan in congestive heart failure patients with reduced ejection fraction.

BACKGROUND: Tolvaptan is a vasopressin type 2 receptor antagonist used in heart failure (HF) with refractory diuretic resistance. However, since tolvaptan is also ineffective in some HF patients with reduced ejection fraction (HFrEF), the identification of responders is important. METHODS: The study population consisted of 51 HFrEF patients who were administered tolvaptan (EF, 28 ±â€¯7%). We defined responders as patients with a ≥50% increase in urine volume during the 24-hours after administration of tolvaptan. All patients underwent comprehensive transthoracic echocardiography before administration of tolvaptan. Patients were followed for 120 days to ascertain secondary events (cardiac death and rehospitalization for HF). RESULTS: Multiple regression analysis indicated that right ventricular (RV) enlargement (defined as basal RV diameter > 41 mm and midlevel RV diameter > 35 mm, according to guidelines) remained a predictor of response after adjustment for age, sex, starting dosage of tolvaptan, and estimated glomerular filtration rate (odds ratio, 4.88; 95%-confidence interval, 1.26-18.9; P < 0.05), whereas left ventricular parameters and RV dysfunction were not. Kaplan-Meier curves indicated responsiveness to tolvaptan was associated with better prognosis among the overall population (P < 0.05); similar trends were observed among patients with RV dilatation (P = 0.056). CONCLUSIONS: These findings suggest that RV enlargement, which represents right-sided volume overload, elevated filling pressure, and diastolic dysfunction similar to that seen in constrictive pericarditis, predicts responsiveness to tolvaptan in patients with HFrEF. Moreover, administration of tolvaptan may have the potential to improve the reportedly poor prognosis for HFrEF patients with RV dilatation.

Greater nighttime blood pressure variability is associated with left atrial enlargement in atrial fibrillation patients with preserved ejection fraction.

Left atrial enlargement is an independent risk factor for ischemic stroke in patients with atrial fibrillation. Little is known regarding the association between nighttime blood pressure variability and left atrial enlargement in patients with atrial fibrillation and preserved ejection fraction. The study population consisted of 140 consecutive patients with atrial fibrillation (mean age 64 ± 10 years) with preserved ejection fraction (≥50%). Nighttime blood pressure was measured at hourly intervals, using a home blood pressure monitoring device. Nighttime blood pressure variability was expressed as the standard deviation of all readings. Left atrial volume index was measured using the modified Simpson's biplane method with transthoracic echocardiography. Multiple regression analysis indicated that nighttime mean systolic/diastolic blood pressure and its variability remained independently associated with left atrial enlargement after adjustment for age, sex, anti-hypertensive medication class, and left ventricular mass index (P < 0.01). When patients were divided into four groups according to nighttime blood pressure and its variability, the group with higher nighttime blood pressure and its variability had significantly larger left atrial volume than the group with lower nighttime blood pressure and its variability (46.6 ml/m2 vs. 35.0 ml/m2, P < 0.0001). Higher nighttime blood pressure and its variability are associated with left atrial enlargement. The combination of nighttime blood pressure and its variability has additional predictive value for left atrial enlargement. Intensive intervention for these high-risk patients may avoid or delay progression of left atrial enlargement and reduce the risk of stroke.

Massive Macroglossia After Posterior Cranial Fossa Surgery: A Case Report.

A 16-year-old boy with Chiari 1 malformation presented for an elective suboccipital craniectomy and C1 laminectomy. His intraoperative course was uneventful. At the conclusion of the procedure, he met extubation criteria and followed commands. After extubation, he developed progressive upper airway obstruction and became obtunded. He was reintubated via videolaryngoscopy, which showed edema not only to the tongue, but also to the posterior pharynx and blisters over the vocal folds and epiglottis. The patient was transferred to the pediatric intensive care unit intubated and sedated. This report describes the clinical course of his massive macroglossia and discusses short- and long-term management.

Synthesis of 3-[4-(dimethylamino)phenyl]alkyl-2-oxindole derivatives and their effects on neuronal cell death.

Novel 3-[4-(dimethylamino)phenyl]alkyl-2-oxindole analogs were synthesized by either of the following two pathways: (1) a sequence of Knoevenagel condensation of oxindole with (4-dimethylamino)cinnamaldehyde-hydrogenation, or (2) alkylation of oxindole dianion with [(4-dimethylamino)phenyl]alkyl halides. Subsequent alkylation at C-3 and/or N-1 of the oxindole skeleton by anion-based methods provided additional substituted derivatives for structure-activity relationship studies. Their effects on neuronal cell death induced by oxidative stress were evaluated by lactate dehydrogenase assay. Compounds with the alkyl chain length of 2-4 significantly suppressed the neuronal cell death. No significant change occurred in the activity by substitution with less-polar groups. The stereochemistry at C-3 of the oxindole core was also irrelevant for the neuroprotective effects of these compounds.

National Survey on Pediatric Acute Agitation and Behavioral Escalation in Academic Inpatient Pediatric Care Settings.

BACKGROUND: Pediatric acute agitation and behavioral escalation (PAABE) is common and disruptive to pediatric inpatient health care. There is a paucity of literature on PAABE in noncritical care inpatient pediatric care settings with little consensus on its evaluation and management. METHODS: In January 2016, a 34-question survey was e-mailed to pediatric hospitalists and consultation-liaison psychiatrists through their respective professional listservs. Excluded responses included incomplete surveys, and surveys from providers in community care settings. The survey consisted of multiple-choice questions, rating scales, and free-text responses relating to the identification, education, and evaluation and management of PAABE at the respondent's respective hospital. RESULTS: Responses were obtained from 38 North American academic children's hospitals. Of the respondents, 69.3% were pediatric hospitalists and 30.7% were pediatric psychiatry consultants. Most respondents practice in urban areas (84.2%), and in hospitals with ≥100 beds (89.4%). Overall, 84.2% of the respondents encountered PAABE at least once a month and as frequently as every week. Most respondents (70.0%) rated PAABE as an 8 or higher on a 10-point Likert scale. Despite being highly important and common, 53.9% of respondents do not screen for risk factors for PAABE, 63.6% reported no formal process to facilitate caregiver involvement in managing PAABE, and 59.7% indicated no physician training in PAABE evaluation and management. CONCLUSION: Many pediatric hospitals identify PAABE as a great concern, yet there is little training, screening, or standardization of care in PAABE. There is a need to consolidate existing knowledge regarding PAABE, while developing enhanced collaboration, training, and standardized practice in inpatient PAABE.

Delirium in Critically Ill Children: An International Point Prevalence Study.

OBJECTIVES: To determine prevalence of delirium in critically ill children and explore associated risk factors. DESIGN: Multi-institutional point prevalence study. SETTING: Twenty-five pediatric critical care units in the United States, the Netherlands, New Zealand, Australia, and Saudi Arabia. PATIENTS: All children admitted to the pediatric critical care units on designated study days (n = 994). INTERVENTION: Children were screened for delirium using the Cornell Assessment of Pediatric Delirium by the bedside nurse. Demographic and treatment-related variables were collected. MEASUREMENTS AND MAIN RESULTS: Primary study outcome measure was prevalence of delirium. In 159 children, a final determination of mental status could not be ascertained. Of the 835 remaining subjects, 25% screened positive for delirium, 13% were classified as comatose, and 62% were delirium-free and coma-free. Delirium prevalence rates varied significantly with reason for ICU admission, with highest delirium rates found in children admitted with an infectious or inflammatory disorder. For children who were in the PICU for 6 or more days, delirium prevalence rate was 38%. In a multivariate model, risk factors independently associated with development of delirium included age less than 2 years, mechanical ventilation, benzodiazepines, narcotics, use of physical restraints, and exposure to vasopressors and antiepileptics. CONCLUSIONS: Delirium is a prevalent complication of critical illness in children, with identifiable risk factors. Further multi-institutional, longitudinal studies are required to investigate effect of delirium on long-term outcomes and possible preventive and treatment measures. Universal delirium screening is practical and can be implemented in pediatric critical care units.

A Previously Healthy Adolescent With Acute Encephalopathy and Decorticate Posturing.

A 14-year-old previously healthy female was transferred from a local emergency department after being found unresponsive at home. Parental questioning revealed she had fever and pharyngitis 2 weeks before presentation. Past mental health history was negative, including concern for past or present suicidal ideation/attempts, suspected substance use, or toxic ingestion. In the emergency department, she was orotracheally intubated due to a Glasgow Coma Scale of 3. She was hemodynamically stable and euglycemic. Electrocardiogram showed sinus tachycardia. She underwent a noncontrast head computed tomography that was normal and subsequently underwent a lumbar puncture. She had a seizure and was given a loading dose of diazepam and fosphenytoin that led to cessation of extremity movements. She was subsequently transferred to the PICU for additional evaluation. Initial examination without sedation or analgesia demonstrated dilated and minimally responsive pupils, intermittent decorticate posturing, and bilateral lower extremity rigidity and clonus, consistent with a Glasgow Coma Scale of 5. Serum studies were unremarkable with the exception of mild leukocytosis. Chest radiograph only showed atelectasis. She was empirically started on antibiotics to cover for meningitis pending final cerebral spinal fluid test results. The pediatric neurology team was consulted for EEG monitoring, and the patient was eventually sent for computed tomography angiogram and magnetic resonance angiogram/venogram. We will review diagnostic evaluation and management of an adolescent patient with acute encephalopathy with decorticate posturing of unclear etiology.

Therapeutic plasma exchange may improve hemodynamics and organ failure among children with sepsis-induced multiple organ dysfunction syndrome receiving extracorporeal life support.

OBJECTIVE: To determine the effect of therapeutic plasma exchange on hemodynamics, organ failure, and survival in children with multiple organ dysfunction syndrome due to sepsis requiring extracorporeal life support. DESIGN: A retrospective analysis. SETTING: A PICU in an academic children's hospital. PATIENTS: Fourteen consecutive children with sepsis and multiple organ dysfunction syndrome who received therapeutic plasma exchange while on extracorporeal life support from 2005 to 2013. INTERVENTIONS: Median of three cycles of therapeutic plasma exchange with median of 1.0 times the estimated plasma volume per exchange. MEASUREMENTS AND MAIN RESULTS: Organ Failure Index and Vasoactive-Inotropic Score were measured before and after therapeutic plasma exchange use. PICU survival in our cohort was 71.4%. Organ Failure Index decreased in patients following therapeutic plasma exchange (mean ± SD: pre, 4.1 ± 0.7 vs post, 2.9 ± 0.9; p = 0.0004). Patients showed improved Vasoactive-Inotropic Score following therapeutic plasma exchange (median [25th-75th]: pre, 24.5 [13.0-69.8] vs post, 5.0 [1.5-7.0]; p = 0.0002). Among all patients, the change in Organ Failure Index was greater for early therapeutic plasma exchange use than late use (early, -1.7 ± 1.2 vs late, -0.9 ± 0.6; p = 0.14), similar to the change in Vasoactive-Inotropic Score (early, -67.5 [28.0-171.2] vs late, -12.0 [7.2-18.5]; p = 0.02). Among survivors, the change in Organ Failure Index was greater among early therapeutic plasma exchange use than late use (early, -2.3 ± 1.0 vs late, -0.8 ± 0.8; p = 0.03), as was the change in Vasoactive-Inotropic Score (early, -42.0 [16.0-76.3] vs late, -12.0 [5.3-29.0]; p = 0.17). The mean duration of extracorporeal life support after therapeutic plasma exchange according to timing of therapeutic plasma exchange was not statistically different among all patients or among survivors. CONCLUSIONS: The use of therapeutic plasma exchange in children on extracorporeal life support with sepsis-induced multiple organ dysfunction syndrome is associated with organ failure recovery and improved hemodynamic status. Initiating therapeutic plasma exchange early in the hospital course was associated with greater improvement in organ dysfunction and decreased requirement for vasoactive and/or inotropic agents.

Clinical picture and social characteristics of super-elderly patients with heart failure in Japan.

The number of super-elderly patients older than 80 years with chronic heart failure (HF) is dramatically increased in Japan; however, therapeutic strategies for patients 80 years or older remains to be established. The present investigation was undertaken to clarify the clinical picture and socioeconomic characteristics of super-elderly HF patients. A total of 380 consecutive patients with acute HF or acutely worsening chronic HF were divided into three groups according to age: patients younger than 60 years, those 60 to 80 years, and those 80 years or older (super-elderly group). HF patients in the super-elderly group initially presented with more atypical symptoms at admission compared with those in the younger age group. The prevalence of HF with preserved ejection fraction was more pronounced compared with the patients in the younger age group. Furthermore, the social background was quite different for the 3 groups in several respects: recurrent hospitalization, the prevalence of dementia, and the number of patients living alone all increased with age. The lack of social support in patients with HF is a problem that needs to be resolved in the "super-graying" societies such as Japan.
