The Ability of Critical Care Physicians to Identify Patient-Ventilator Asynchrony Using Waveform Analysis: A National Survey.

BACKGROUND: Improved patient-ventilator asynchrony (PVA) identification using waveform analysis by critical care physicians (CCPs) may improve patient outcomes. This study aimed to assess the ability of CCPs to identify different types of PVAs using waveform analysis as well as factors related to this ability. METHODS: We surveyed 12 university-affiliated medical ICUs (MICUs) in Tunisia. CCPs practicing in these MICUs were asked to visually identify 4 clinical cases, each corresponding to a different PVA. We collected the following characteristics regarding CCPs: scientific grade, years of experience, prior training in mechanical ventilation, prior exposure to waveform analysis, and the characteristics of the MICUs in which they practice. Respondents were categorized into 2 groups based on their ability to correctly identify PVAs (defined as the correct identification of at least 3 of the 4 PVA cases). Univariate analysis was performed to identify factors related to the correct identification of PVA. RESULTS: Among 136 included CCPs, 72 (52.9%) responded to the present survey. The respondents comprised 59 (81.9%) residents, and 13 (18.1%) senior physicians. Further, 50 (69.4%) respondents had attended prior training in mechanical ventilation. Moreover, 21 (29.2%) of the respondents could correctly identify PVAs. Double-triggering was the most frequently identified PVA type, 43 (59.7%), followed by auto-triggering, 36 (50%); premature cycling, 28 (38.9%); and ineffective efforts, 25 (34.7%). Univariate analysis indicated that senior physicians had a better ability to correctly identify PVAs than residents (7 [53.8%] vs 14 [23.7%], P = .044). CONCLUSIONS: The present study revealed a significant deficiency in the accurate visual identification of PVAs among CCPs in the MICUs. When compared to residents, senior physicians exhibited a notably superior aptitude for correctly recognizing PVAs.

Bi-allelic variants in HCRT cause autosomal recessive narcolepsy.

Narcolepsy with cataplexy is a complex disease with both genetic and environmental risk factors. To gain further insight into the homozygous HCRT-related narcolepsy, we present a case series of five patients from two consanguineous families, each harboring a novel homozygous variant of HCRT c.17_18del. All affected individuals exhibited severe cataplexy accompanied by narcolepsy symptoms during infancy. Additionally, cataplexy symptoms improved or disappeared in the majority of patients over time. Pathogenic variants in HCRT cause autosomal recessive narcolepsy with cataplexy. Genetic testing of the HCRT gene should be conducted in specific subgroups of narcolepsy, particularly those with early onset, familial cases, and a predominantly cataplexy phenotype.

Acute Flaccid Myelitis in a Pediatric Patient With Coronavirus Disease 2019.

The etiology of acute flaccid myelitis (AFM) has yet to be determined. Viral link has been suggested, but severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-associated AFM has not been reported in children. We describe a three-year-old boy, with AFM associated with coronavirus disease 2019 (COVID-19) infection. In the era of COVID-19 pandemic, patients with AFM should be tested for SARS-CoV-2.

Spontaneous Hemopericardium Complicated by Tamponade in a Child With Moderate Hemophilia A: Case-Based Review.

Hemophilia A is the most common severe innate bleeding disorder. It is an X-linked recessive inherited bleeding disorder characterized by a qualitative and/or quantitative deficiency of factor VIII. The clinical manifestation of this disease is hemorrhaging that can affect every organ, in particular joints (hemarthrosis) and muscles (hematoma). Some serious but rare hemorrhages can be life-threatening, in particular hemorrhage of the central nervous system and hemopericardium. We report a rare case of spontaneous hemopericardium complicated by tamponade in a child with moderate hemophilia A treated with Factor VIII replacement infusion and pericardial drainage, with a favorable outcome. To our knowledge, this is the second case described in the literature of spontaneous hemopericardium occurring in a child with hemophilia A. Our case suggests that a dose of 50 IU/kg/8 h of factor VIII maintained for up to one day after removal of the pericardial drain seems to be sufficient to ensure correct hemostasis, though further evidence is needed to confirm this impression.

Common sleep disorders in children: assessment and treatment.

Pediatric sleep disorders are a common, mainly among children with pre-existing disabilities, neurological conditions, and neurodevelopmental disorders. The consequences are variable, and sleep disorders may be associated with deficits in neurocognitive performance and growth failure. Rising awareness about sleep disorders among pediatricians will improve the early diagnosis and management of these disorders. This review describes normal sleep patterns in infants and children and provide a recent update on common sleep disorders that improve the diagnosis and treatment of children with sleep disorders.

Awareness and management of intra-abdominal hypertension and abdominal compartment syndrome by paediatric intensive care physicians: a national survey.

INTRODUCTION: This study aimed to evaluate the current awareness and management of intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) among paediatric intensivists. MATERIAL AND METHODS: A web-based electronic survey was sent to all physicians working in paedia-tric intensive care units (PICUs) in Saudi Arabia. The survey questions obtained information regarding awareness of ACS and IAH, recognition criteria, monitoring of intra-abdominal pressure (IAP), and experience in managing ACS. RESULTS: A total of 79 physicians responded to the survey (response rate: 53%). Among respondents 48% were consultants. 85% of respondents were familiar with IAP/IAH/ACS. Only 35% and 10% were aware of the Abdominal Compartment Society consensus definitions for IAH and ACS in the paediatric population, respectively. Most respondents considered the cut-off for IAH to be ≥ 15 mm Hg, and approximately two-thirds thought that the cut-off for ACS was higher than the currently suggested consensus definition (10 mm Hg). More than two-thirds of respondents monitored IAP in the PICU, and it was measured almost exclusively via the bladder (96%); the majority (70%) reported that they instilled volumes well above the current recommendations. Medical management was the most frequent therapeutic approach to treat IAH/ACS, while surgical decompression was the least attempted option. Decisions to decompress the abdomen were predominantly based on the presence of organ dysfunction (74.4%). CONCLUSIONS: This survey showed that although most responding physicians claim to be familiar with IAH and ACS, their knowledge of published consensus definitions, measurement techniques, and clinical management must be updated.

High-fidelity simulation versus video-based learning in the management of pediatric septic shock: a pilot study.

High-fidelity simulation (HFS) and video-based learning (VBL) promote competence in acute care in a realistic and safe environment. These two modalities have not been compared in pediatric emergency situations. Interns rotating in the pediatric department were randomized for the two educational methods. The delivered learning subject was septic shock in children. The level of knowledge was measured before intervention, immediately after intervention (post-test 1) and 1 week later (post-test 2). Knowledge test scores improved significantly following intervention in both VBL study group and HFS study group (71.5 ± 13.2 [39.0-88.0], p < 0.001 and 80.1 ± 10.3 [57.4-94.5], p < 0.001, respectively). The improvement was significantly higher in HFS study group (p = 0.04). There was a non-significant drop in the retention score evaluated by the post-test 2 in the two groups compared to the post-test 1 score (66.9 ± 15.4 [31.5-86.1], p = 0.17 and 78.8 ± 12.4 [56.0-100.0], p = 0.72 in the VBL and HFS study groups, respectively). The retention score was significantly higher in the HFS group (p = 0.04).Conclusion: High-fidelity simulation and video-based training are both effective educational methods in teaching pediatric emergencies for interns. HFS appears to be superior in enhancing short-term retention. What is Known: • High-fidelity simulation is an effective educational tool to improve learners' knowledge and skills. • Video-based learning is an effective teaching tool in terms of short-term knowledge acquisition. What is New: • High-fidelity simulation is more effective in terms of short-term knowledge and generated more satisfaction than educational video learning.

Problem-solving in clinical practice: breathing difficulty and muscle weakness following allogeneic haematopoietic stem cell transplantation.

Acute weakness and dyspnoea are unusual presentation after allogeneic haematopoietic stem cell transplantation (HSCT) complicated by chronic graft-versus-host disease (GVHD). The differential diagnosis and management are challenging for the paediatrician. This case chronicles the diagnostic journey of a child who presented with weakness, dyspnoea and difficulty in speech, 2 years after allogeneic HSCT and GVHD and explores the approach to neurological manifestations in this context.

Off-Hours Admissions and Mortality in PICU Without 24-Hour Onsite Intensivist Coverage.

OBJECTIVE: To evaluate whether the off-hours admission has any effect on risk-adjusted mortality and length of stay for nonelective patients admitted to a pediatric intensive care unit (PICU) without 24-hour in-house intensivist coverage. DESIGN: Prospective cohort study. SETTING: A 34-bed tertiary PICU. PATIENTS: All consecutive nonelective patients aged 0 to 14 years admitted from January 2012 to June 2015. MEASUREMENTS AND MAIN RESULTS: A total of 1254 patients were nonelectively admitted to the PICU. They were categorized according to time of PICU admission as either office hours (07:30 to 16:30 from Sunday to Thursday and whenever an intensivist is present in the ICU) or off-hours (16:30 to 07:30, Friday and Saturday and public holidays). Standardized mortality rates (SMRs) of patients admitted during off-hours were compared to SMRs of patients admitted during office hours using Pediatric Risk of Mortality (PRISM2) score. Multivariate logistic regression was used to assess the effect of time of admission on outcome after adjustment for severity of illness using the PRISM2. The mortality observed in the office-hours group was 9.4% and in the off-hours group was 8.1%. The PRISM2-based SMR was 0.83 (95% confidence interval [CI]: 0.43-1.47) for the office-hours group and 0.68 (95% CI: 0.34-1.36) for the off-hours group. No significant differences in length of ICU stay or duration of mechanical ventilation were observed between patients admitted during off-hours and those admitted during office hours. In the logistic regression model, off-hours admission was not significantly associated with a higher mortality (odds ratio: 0.85, 95% CI: 0.57-1.27; P = .44). CONCLUSIONS: The absence of an in-house intensivist during off-hours is not associated with an increase in mortality, length of ICU stay, or duration of mechanical ventilation for patients admitted to our pediatric ICU.

Intra-abdominal hypertension and abdominal compartment syndrome in pediatrics. A review.

PURPOSE: To consolidate pediatric intensivists' understanding of the pathophysiology, definition, incidence, monitoring, and management of intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS); and to highlight the characteristics related to the pediatric population. METHODS: This is a narrative review article that utilized a systematic search of the medical literature published in the English language between January 1990 and august 2016. Studies were identified by conducting a comprehensive search of Pub Med databases. Search terms included "intra-abdominal hypertension and child", "intra-abdominal hypertension and pediatrics", "abdominal compartment syndrome and child", and "abdominal compartment syndrome and pediatrics". RESULTS: Intra-abdominal hypertension and ACS are associated with a number of pathophysiological disturbances and increased morbidity and mortality. These conditions have been well described in critically ill adults. In children, the IAH and the ACS have a reported incidence of 13% and 0.6 to 10% respectively; they carry similar prognostic impact but are still under-diagnosed and under-recognized by pediatric health care providers. CONCLUSIONS: Intra-abdominal hypertension and ACS are conditions that are regularly encountered in critically ill children. They are associated with an increased morbidity and mortality. Early recognition, prevention and timely management of this critical condition are necessary to improve its outcome.

Adherence to surviving sepsis guidelines among pediatric intensivists. A national survey.

OBJECTIVES: To assess the compliance with the 2006 American College of Critical Care-Pediatric Advanced Life Support (ACCM-PALS) guidelines for sepsis management, and the 2012 surviving sepsis campaign (SSC), for the management of pediatric patients with sepsis and to identify the main barriers to adherence to these guidelines. Methods: In November 2015, a prospective cohort study in which a web based electronic survey using a case scenario to explore the usual management of a child with severe sepsis was designed and sent to all consultant pediatric intensivists practicing in Kingdom of Saudi Arabia (KSA). Adherences to 2012 SSC guidelines and to 4 algorithmic time-specific goals outlined in the ACCM-PALS guidelines were measured. Results: Sixty-one (76%) of 80 consultant pediatric intensivists working in KSA responded to the survey. Of the 61 respondents, 94% reported administering antibiotics within one hour of the child presentation, 98% reported starting resuscitation by giving fluid boluses, 93% reported starting vasopressor if the patient remained hypotensive despite fluid resuscitation, and 86% reported they would start hydrocortisone in case of catecholamine refractory shock. In total, 80% of the intensivists reported full adherence to all of the 4 components in the ACCM-PALS bundle; 50% reported that the absence of a locally written protocol was the main barrier to adherence to the SSC guidelines. Conclusion: Pediatric intensivists reported good adherence to the 2006 ACCM-PALS guidelines and 2012 SSC guidelines with some variability in interpretation of the recommendations. The absence of a written protocol was the main reported barrier to adherence to these guidelines.

Incidence, Risk Factors, and Prognosis of Intra-Abdominal Hypertension in Critically Ill Children: A Prospective Epidemiological Study.

PURPOSE: To assess the incidence, risk factors, and outcomes of intra-abdominal hypertension (IAH) in a pediatric intensive care unit (PICU). METHODS: Prospective cohort study from January 2011 to January 2013. All children consecutively admitted to the PICU, staying more than 24 hours and requiring bladder catheterization, were included in the study. On admission, demographic data and risk factors for IAH were studied. The intra-abdominal pressure was measured every 6 hours through a bladder catheter until discharge, death, or removal of the catheter. RESULTS: Of the 175 patients, 22 (12.6%) had IAH and 7 (4%) had abdominal compartment syndrome during the intensive care unit (ICU) stay. The independent risk factors associated with IAH were the presence of abdominal distension (odds ratio [OR] 7.1; 95% confidence interval [CI], 2.6-19.9; P < .0001) and a plateau pressure of more than 30 cm H2O (OR 6.42; 95% CI, 2.13-19.36; P = .01). The presence of IAH was associated with higher mortality (40.9% vs 15.6%; P = .01) and prolonged ICU stay (19.5 [3-97] vs 8 [1-104] days, OR 1.02; 95% CI, 1.00-1.04; P = .02). Thirty-three (18.8%) patients died in the ICU, and IAH was an independent risk factor for mortality (OR 6.98; 95% CI, 1.75-27.86; P = .006). CONCLUSION: Intra-abdominal hypertension does occur in about 13% of the critically ill children, albeit less frequently than adult patients, probably related to a better compliance of the abdominal wall. The presence of abdominal distension and a plateau pressure of more than 30 cm H2O was found to be independent predictors of IAH. Children with IAH had higher mortality rate and more prolonged ICU stay.

Pilot trial of a novel two-step therapy protocol using nebulized tranexamic acid and recombinant factor VIIa in children with intractable diffuse alveolar hemorrhage.

BACKGROUND AND OBJECTIVES: Diffuse alveolar hemorrhage (DAH) is a life threatening condition with very limited, often unsuccessful, therapeutic options. This study aimed at exploring the feasibility and efficacy of nebulized tranexamic acid TXA (n-TXA) and nebulized recombinant factor VIIa (n-rFVIIa) when used in a two-step therapy protocol in children with intractable DAH in a pediatric intensive care unit. METHODS: In a prospective trial, n-TXA (250 mg/dose for children < 25 kg and 500 mg/dose for children > 25 kg) was administered to 18 children (median age [interquartile range]; 24.0 months [11.3, 58.5]) with intractable DAH. N-rFVIIa (35 micro g/kg/dose for children < 25 kg, and 50 micro g/kg/dose for children > 25 kg) was added if no or minimal response was seen after 3 to 4 doses (18 to 24 hours) of n-TXA. RESULTS: DAH was stopped in 10 (55.6%) children with n-TXA alone within 24 hours of therapy. Documented concomitant respiratory infection showed a significant negative association with response to n-TXA in a step.wise regression analysis (OR=0.06; 95% CI=0.01-0.74). In the other 8 (44.4%) children, n-rFVIIa was added due to n-TXA failure. Six (75.0%) showed complete cessation of DAH, while two children failed to respond with the addition of n-rFVIIa (25.0%). None of the children who responded to therapy showed recurrence of DAH after therapy termination. No complications related to therapy were recorded. CONCLUSIONS: n-TXA and n-rFVIIa were effective and safe when used in a two-step-therapy protocol to control intractable DAH in pediatric patients in intensive care settings. This therapy modality warrants further exploration through larger multicenter clinical trials.

Middle East respiratory syndrome coronavirus in children.

The Middle East respiratory syndrome (MERS) is a new human disease caused by a novel coronavirus (CoV). The disease is reported mainly in adults. Data in children are scarce. The disease caused by MERS-CoV in children presents with a wide range of clinical manifestations, and it is associated with a lower mortality rate compared with adults. Poor outcome is observed mainly in admitted patients with medical comorbidities. We report a new case of MERS-CoV infection in a 9-month-old child complicated by severe respiratory symptoms, multi-organ dysfunction, and death. We reviewed the literature in an attempt to characterize the mode of presentation, the risk factors, and outcome of MERS-CoV infection in the pediatric population.

Utility of daily routine portable chest X-ray in mechanically ventilated patients in the pediatric intensive care unit.

The utility of daily routine chest X-rays (CXRs) in mechanically ventilated patients in intensive care units is still controversial. The present study compared the diagnostic, therapeutic and outcome efficacy between daily routine and non-routine (clinically indicated) CXRs in children patients in pediatric intensive care unit (PICU). A prospective randomized study conducted in tertiary center 18-bed PICU, Riyadh Military Hospital, Riyadh, Kingdom of Saudi Arabia. The study selected 52 children, who were mechanically intubated for at least 48 hr. The children were randomized to receive either routine (29 patients) or non-routine (23 patients) CXRs and were followed until extubation or death. Demographic and outcome data were collected and analyzed as appropriate. Although children in the non-routine group received fewer CXRs, the lengths of stay (LOS) in intensive care unit and hospital and mortality rate were nearly the same compared with routine group. The percentage of CXRs with new findings was higher in the non-routine group (83%; 53 CXRs) compared to that in the routine group (69%; 156 CXRs) with an odds ratio (OR) of 2.10 (95% confidence interval [CI] = 0.60-8.11). Also, the percentage of CXRs with new findings that result in intervention was higher in non-routine group (78% vs. 69%; OR = 1.60; 95% CI = 0.50-5.70). The daily routine CXRs was not associated with a reduced effect on length of stay in PICU and hospital or mortality and it does not seem to add any advantages over non-routine CXRs in PICU. Large multicenter studies are needed to confirm these results.

Septic pulmonary embolism secondary to Staphylococcus aureus septic thrombophlebitis in a pediatric patient.

We present the clinical course of an 11-year-old child with septic pulmonary embolism secondary to community acquired methicillin-resistant Staphylococcus aureus (MRSA) septic deep venous thrombosis. The aim is to emphasize the non-specific symptoms of septic pulmonary embolism in pediatrics, the frequent association with septic deep venous thrombosis and osteomyelitis, and to highlight that MRSA is the most frequently isolated organism. Pediatricians should consider septic pulmonary embolism in cases of septic deep venous thrombosis even in the absence of respiratory symptoms. The initial antibiotic management should include glycopeptides, as community acquired MRSA is increasingly the isolated organism in this disorder.

Acute necrotizing encephalopathy associated with enterovirus infection.

Acute necrotizing encephalopathy is a rare, clinically distinct entity of acute encephalopathy triggered by acute febrile diseases, mostly viral infections. It is postulated to arise from uncontrolled cytokine release during a febrile illness, and is most often seen in East Asia. We describe a rare Saudi patient of acute necrotizing encephalopathy attributable to enterovirus in a 4 years and 6 months old girl. A work-up revealed elevations in serum and cerebrospinal fluid interleukin-6 and tumor necrosis factor-α. The outcome on intravenous pulse methylprednisolone was good. This case is the first, to the best of our knowledge, of acute necrotizing encephalopathy reported from Saudi Arabia with a good outcome despite severe magnetic resonance imaging findings and delay in the steroid treatment.

Shock: an unusual presentation of Kawasaki disease.

UNLABELLED: Kawasaki disease (KD) is a common acute systemic vasculitis of childhood. Although KD has wide spectrum of clinical features, shock is not one of its common presentation form. We describe a 5-month-old female infant with severe shock syndrome requiring fluid resuscitation, inotropic support, and PICU admission. She was diagnosed retrospectively to have KD complicated by coronary artery aneurysms in spite of receiving early course of IV immunoglobulin. CONCLUSION: Diagnosis of KD could be missed in the pediatric intensive care unit because of its atypical presentation and the wide array of associated clinical symptoms. Subsequently, intensivists and emergency room physicians should maintain a high index of suspicion not to miss it or diagnose it at an advanced stage of the illness.

Cefepime-induced nonconvulsive status epilepticus: case report and review.

INTRODUCTION: A case of cefepime-induced nonconvulsive status epilepticus in a 15-year-old child with end stage renal disease on hemodialysis is reported. Clinical symptoms and EEG dramatically improved 48 h after discontinuation of cefepime. METHODS: Twenty-five cases of nonconvulsive status epilepticus associated with cefepime that have been reported in the literature are reviewed. RESULTS: The average age was 60 years [15-86], our patient is the second pediatric patient reported, and 56% of cases occurred in women. The cefepime dosage was adjusted to the renal function in 5 cases. All except 1 patient have impaired renal function (CRF: 17 cases, ARF: 7 cases). The symptoms start 1-15 days after starting cefepime, mean 6 days. The outcome was good after discontinuation of cefepime therapy and anticonvulsant treatment, but lethal outcome was also reported in 2 cases. One fatality was related to status epilepticus. CONCLUSION: The clinicians' awareness must be increased about cefepime-induced nonconvulsive status epilepticus.
