Clinical characteristics and outcomes of continuous renal replacement therapy performed on younger children weighing up to 10 kg.

BACKGROUND: This study aimed to investigate the clinical features, modality, complications, and effecting factors on the survival of children weighing up to 10 kg who received continuous renal replacement therapy (CRRT). METHODS: This study was a retrospective observational study conducted in five pediatric intensive care units in tertiary hospitals in Turkey between January 2015 and December 2019. RESULTS: One hundred and forty-one children who underwent CRRT were enrolled in the study. The median age was 6 (range, 2-12)months, and 74 (52.5%) were male. The median weight of the patients was 6 (range, 4-8.35) kg and 52 (36.9%) weighed less than 5 kg. The most common indication for CRRT was fluid overload in 75 (53.2%) patients, and sepsis together with multiorgan failure in 62 (44%). The overall mortality was 48.2%. DISCUSSION: Despite its complexity, CRRT in children weighing less than 10 kg is a beneficial, lifesaving extracorporeal treatment modality.

The Burden of Burnout Syndrome in Pediatric Intensive Care Unit and Pediatric Emergency Department: A Multicenter Evaluation.

OBJECTIVE: The objective of this study was to detect variables associated with burnout syndrome (BS) in pediatric intensive care units (PICUs) and pediatric emergency medicine departments (PEDs) in high-volume centers from different parts of Turkey. METHODS: An observational, cross-sectional multicenter study was performed. The Maslach Burnout Inventory scale was administered to all of health care providers working in PICUs and PEDs. In this study, health care providers were defined as physicians, nurses, and other staff (secretaries, cleaning and patient care staff) working in PICU and PEDs. RESULTS: A total of 570 participants completed the survey. The major finding of this study was that 76.1% (n = 434) of PICU and PED health care professionals had BS. The most prominent subscale of BS was emotional exhaustion (62.5%). The rate of BS was higher among health care providers working in PEDs compared with PICUs (79.1% vs 73.7%, P = 0.04). The frequency of BS according to emotional exhaustion and depersonalization subscales was higher in health care providers of PEDs. The rate of BS was also significantly higher in younger employees, females, those working 51 or more hours totally in a week, those having a low monthly salary, those single or divorced, those without children, those with no childcare at home, those not owning a home, those not doing regular exercise and not having regular breakfast, those with total employment time of less than 1 year, and those not having a car or not having a hobby. In PEDs, when the daily evaluated number of patients was equal to or more than 44 (sensitivity, 88%; specificity, 66%), it predicted the occurrence of BS. In PICUs, when the number of patients cared for by 1 nurse was equal to or more than 3, it predicted the occurrence of BS (sensitivity, 78%; specificity, 62%). CONCLUSIONS: By creating early intervention programs to prevent BS, shortages of health care professionals can be avoided and the costs of health care expenditures related to infections can be decreased.

Comprehensive Analysis of Severe Viral Infections of Respiratory Tract admitted to PICUs during the Winter Season in Turkey.

OBJECTIVES: To analyze the course of seasonal viral infections of respiratory tract in patients hospitalized in pediatric intensive care units (PICU) of 16 centers in Turkey. MATERIALS AND METHODS: It is a retrospective, observational, and multicenter study conducted in 16 tertiary PICUs in Turkey includes a total of 302 children with viral cause in the nasal swab which required PICU admission with no interventions. RESULTS: Median age of patients was 12 months. Respiratory syncytial virus (RSV) was more common in patients over one year of age whereas influenza, human Bocavirus in patients above a year of age was more common (p <0.05). Clinical presentations influencing mortality were neurologic symptoms, tachycardia, hypoxia, hypotension, elevated lactate, and acidosis. The critical pH value related with mortality was ≤7.10, and critical PCO2 ≥60 mm Hg. CONCLUSION: Our findings demonstrate that patients with neurological symptoms, tachycardia, hypoxia, hypotension, acidosis, impaired liver, and renal function at the time of admission exhibit more severe mortal progressions. Presence of acidosis and multiorgan failure was found to be predictor for mortality. Knowledge of clinical presentation and age-related variations among seasonal viruses may give a clue about severe course and prognosis. By presenting the analyzed data of 302 PICU admissions, current study reveals severity of viral respiratory tract infections and release tips for handling them.

Seizures in a Pediatric Intensive Care Unit: A Prospective Study.

BACKGROUND: The aim of the research is to determine the etiology and clinical features of seizures in critically ill children admitted to a pediatric intensive care unit (PICU). METHODS: A total of 203 children were admitted from June 2013 to November 2013; 45 patients were eligible. Age ranged from 2 months to 19 years. Seizures were organized as epileptic or acute symptomatic. Pediatric risk of mortality score III, Glasgow coma scale, risk factors, coexistent diagnosis, medications administered before admission, type and duration of seizures, drugs used, requirement and duration of mechanical ventilation, length of stay and neuroimaging findings were collected as demographic data prospectively. RESULTS: The male-female ratio was 0.8. Mean age was 5.4. The most common causes of seizures were acute symptomatic. Most frequent coexistent diagnosis was infectious diseases, and 53.3% had recurrent seizures. Medications were administered to 51.1% of the patients before admission. Seizures were focal in 21 (46.7%), generalized in 11 (24.4%) and 13 (28.9%) had status epilepticus. Intravenous midazolam was first-line therapy in 48.9%. Acute symptomatic seizures were usually new-onset, and duration was shorter. Epileptic seizures tended to be recurrent and were likely to progress to status epilepticus. However, type of seizures did not change severity of the disease. Also, laboratory test results, medications administered before admission, requirement and duration of ventilation, mortality and length of stay were not significant between epileptic/acute symptomatic patients. CONCLUSION: Seizures in critically ill children, which may evolve into status epilepticus, is an important condition that requires attention regardless of cause. Intensified educational programs for PICU physicians and international guidelines are necessary for a more efficient approach to children with seizures.

Studying IFN-gamma, IL-17 and FOXP3 in pediatric lupus nephritis.

BACKGROUND: We studied the cytokines secreted by the inflammatory T cell subgroups (IFN-γ and IL-17) and FOXP3 expression in lupus nephritis (LN) and analyzed associations with clinical and histopathological parameters. METHODS: Renal tissue samples of 39 LN patients were studied. Immunohistochemical staining was carried out with antibodies against IFN-γ, IL-17, and FOXP3. RESULTS: Both IFN-γ (+) and IL-17+ cells were statistically higher in LN tissues when compared with controls (p < 0.01). The cells in the tubulointerstitium were CD3 + CD4+ displaying a Th1 and Th17 phenotype, whereas the less intense population in the glomeruli was CD3-CD4-. Interstitial CD3 + CD4+ FOXP3+ cells were also significantly higher in LN biopsies than in control tissues (p < 0.01). IFN-γ (+) and IL-17+ cells were more intense among class IV LN as compared to class II, III LN (p < 0.01 and p = 0.001, respectively). Subsequently, when IL-17 and IFN-γ staining was compared between the proliferative LN classes, class III and IV patients had more intense staining compared to class II (all p < 0.05). IFN-γ immunostaining correlated positively with serum creatinine and negatively with albumin levels and glomerular filtration rate (GFR). IL-17 immunostaining correlated with proteinuria, requirement for pulse steroids, and SLEDAI renal score, and negatively with GFR. Furthermore, glomerular and interstitial IL-17 and IFN-γ stainings were significantly associated with various parameters of histological activity (p < 0.05). CONCLUSION: We suggest that IFN-gamma and IL-17 could have a role in the pathogenesis and progression of LN. The Th1 and Th17 cells may be imperative in the severity of LN. Recognizing the complexity of the immune pathways involved in lupus reminds us that targeting B cells only may not suffice to control the progression of the inflammation.

Intracardiac thrombus in children: the fine equilibrium between the risk and the benefit.

The medical records of 16 patients diagnosed as intracardiac thrombus were searched. The size, location and outcome of thrombus together with demographic data of patients were assessed. The median age of the patients was 2.2 years. Six patients were newborn and two patients were infant. The median size of thrombus was 9 mm. The localization was right atrium in seven, right ventricle in five, left ventricle in one, pulmonary artery in one, and superior vena cava in two patients. There was prematurity in five, ciyanotic congenital heart disease in one, blood culture positivity in three, malignancy in four, nephrotic syndrome in one, indwelling catheters in 10, and acquired or genetic thrombophilia in six patients as risk factors. In the treatment, the first choice was tissue plasminogen activator in two patients, heparin infusion in one patient and low molecular weight heparin in remaining 12 patients. In nine patients, therapy included parenteral antimicrobials together with anticoagulants. The result was complete resolution in 15 patients and in one patient thrombus was surgically removed. The median time was 16 (2-70) days for 50% resolution and 26 (3-93) days for complete resolution. There was a statistically significant (P = .027 and r = 0.5) correlation between the size and the complete resolution time. There was no anticoagulant therapy related major complication. In patients with intracardiac thrombus, selection of anticoagulant therapy may decrease the risk of complications. Surgery is rarely required and thrombolytics are not usually necessary for resolution of thrombus.

Effect of cardiopulmonary bypass on thiol/disulfide homeostasis in congenital heart surgery.

Background: This study aims to investigate whether thiol/disulfide homeostasis parameters measurements could be used as a new biomarker to predict the pre- and post-cardiopulmonary bypass oxidative status of pediatric patients undergoing congenital heart surgery. Methods: A total of 40 children with congenital heart disease (17 males, 23 females; mean age: 39.6±40.0 months; range, 2 to 216 months) who underwent open-heart surgery were included. The control group consisted of 40 age- and sex-matched healthy children (18 males, 22 females; mean age: 42.8±46.6 months; range, 12 to 156 months). The patients with congenital heart disease were divided into two groups as cyanotic patients (n=18) and acyanotic patients (n=22). Thiol/disulfide parameters were compared among the cyanotic, acyanotic congenital heart disease patients, and control group preoperatively (pre-CPB). The effects of cardiopulmonary bypass on thiol/disulfide parameters, pre-CBP, immediately after cardiopulmonary bypass (post-CPB0), and 24 h after cardiopulmonary bypass (post-CPB24) were investigated. Results: The mean native and total thiol levels in the cyanotic patients were significantly lower than those in the acyanotic patients and control group (p<0.0001). The cyanotic group exhibited higher disulfide levels than the acyanotic group (p<0.01). The mean native thiol and total thiol levels significantly decreased in the post-CPB0 (p<0.0001). The mean disulfide levels significantly increased in the post-CPB0 than the pre-CPB values (p<0.001). Post-CPB24 native and total thiol levels were elevated compared to post-CPB0 (p<0.0001). The mean disulfide levels significantly increased in the post-CPB24 period than the post-CPB0 values (p<0.001). The survivor patients responded better to oxidative stress than non-survivor patients. Conclusion: Thiol/disulfide measurement is a promising biomarker in determining the pre- and post-cardiopulmonary bypass oxidative status of pediatric patients undergoing congenital heart surgery. The interpretation of thiol/disulfide levels, pre- and postoperatively, may be used in predicting mortality and outcomes of these patients earlier.

Detrimental Results of COVID-19 Fear to Child Health.

The outbreak of coronavirus disease 2019 (COVID-19) and its consequences have led to fear and anxiety among individuals worldwide. The risk of coronavirus transmission frightens people more than any other health problem they face. Parents have concerns about being infected with COVID-19 and delay accessing hospitals even in an emergency which can be very detrimental to child health. Here, in this article, we would like to present eight patients delayed in admission to the hospital to draw attention to the harmful consequences of COVID-19 fear in the community. Although anxiety and fear are encouraging to take necessary precautions, exaggeration of these emotions may cause greater health problems.

Longitudinally extensive transverse myelitis in childhood: Clinical features, treatment approaches, and long-term neurological outcomes.

AIM: Longitudinally extensive transvers myelitis (LETM) is a rare and disabling condition in childhood. The aim of the present study was to share experiences from our center regarding the treatment features and clinical and radiologic course in our LETM patients in light of the literature data. MATERIAL AND METHOD: The study was designed as cross-sectional and included children who followed for LETM at our pediatric neurology clinic between 2010 and 2019. ATM was diagnosed according to the diagnostic criteria report from the Transverse Myelitis Consortium Working Group. LETM was defined as the presence of spinal cord lesions spanning a length of 3 or more consecutive vertebral segments. The patients' medical records were examined in terms of demographic characteristics, presenting symptoms, history of infection prior to and during LETM, prodromal history, neurological examination, laboratory and radiological findings, clinical course, and treatment. The Barthel Index was used to assess the physical independence in activities of daily living of patients with LETM who were followed for at least one year. RESULTS: A total of 15 (8 girl) patients were included in the study. The patients were between 1 and 17 years of age. Presenting symptoms included inability to walk in 12 patients, incontinence in 9 patients, low back pain in 4 patients, abdominal pain in 2 patients, and inability to use the arms in 2 patients. In Barthel Index assessment of physical independence in activities of daily living, 8 patients were evaluated as completely independent, 3 patients as moderately dependent, and 2 patients as slightly dependent. When the 4 patients with motor area impairment and moderate dependency according to the Barthel Index were examined, it was noted that all of them had been admitted 4 days after the onset of symptoms and that 2 (13.3%) had cervicothoracic involvement and 2 (13.3%) had involvement of the entire cord. CONCLUSION: Shorter delay from symptom onset to initiation of immunomodulatory therapy as well as effective rehabilitation resulted in favorable outcomes, with the most noticeable improvement in the areas of motor function and incontinence.

An intronic variant in BRAT1 creates a cryptic splice site, causing epileptic encephalopathy without prominent rigidity.

BRAT1-related neurodevelopmental disorders are characterized by heterogeneous phenotypes with varying levels of clinical severity. Since the discovery of BRAT1 variants as the molecular etiology of lethal neonatal rigidity and multifocal seizure syndrome (RMFSL, OMIM 614498), these variants have also been identified in patients with milder clinical forms including neurodevelopmental disorder with cerebellar atrophy and with or without seizures (NEDCAS, OMIM 618056), epilepsy of infancy with migrating focal seizures (EIMFS), and congenital ataxia (CA). This study aims to examine the consequences and pathogenicity of a novel homozygous splice site variant in BRAT1 in a patient presenting with migrating focal seizures since birth without prominent rigidity. The patient was born from a consanguineous marriage and has had seizures since the neonatal period. He presented with dysmorphic features, pontocerebellar hypoplasia, and migrating focal seizures. Despite supportive treatment, his symptoms rapidly progressed to intractable myoclonic seizures, bouts of apnea and bradycardia, and arrest of head growth, with no acquisition of developmental milestones. Clinical exome sequencing yielded a novel homozygous splice variant in BRAT1. Genetic analysis based on reverse transcription of the patient's RNA followed by PCR amplifications performed on synthesized cDNA and Sanger sequencing was undertaken, and the functional effect of a BRAT1 variant on splicing machinery was demonstrated for the first time. The severe clinical presentation of migrating focal seizures and pontocerebellar hypoplasia in the absence of rigidity further expands the genotypic and phenotypic spectrum of BRAT1-related neurodevelopmental disorders.

Brain Death and Organ Donation in Paediatric Intensive Care Unit.

OBJECTIVE: The purpose of the present study was to retrospectively analyse the brain death (BD) cases that were specified within the last 8 years in the paediatric intensive care unit of our hospital. METHODS: Archive files and computer records of 23 paediatric cases were analysed. Data on age, gender, conditions that caused BD, paediatric risk of mortality (PRISM III) scores, time between suspicion of BD and issuing of BD report, confirmatory tests used, complications that occurred following the diagnosis of BD and time to cardiac arrest development after diagnosis of BD were recorded. RESULTS: The average age of the patients was 6.8±5.5 years. The most frequent cause of BD was intracranial haemorrhage (30.4%). The mean time to diagnosis after BD suspicion was 5.9±6.2 days. Electroencephalography was performed in 61% of the patients in addition to the apnoea test. Radiological imaging methods were used in 39% of the patients (n=9). Of the cases, 34.7% developed hypothermia, and 4.3% developed diabetes insipidus (DI). Among them, 43.4% had both DI and hypothermia. The mean PRISM score was calculated as 22±9.2. The donation rate of the families was 17%. The mean time to cardiac arrest development after diagnosis of BD was 6.9±7.4 days in non-donor cases where medical support had been reduced. CONCLUSION: Any patient with a neurologically poor prognosis in the intensive care unit should be considered to develop BD and diagnosed with BD without delay. The donation rate will increase if family interviews are done by an experienced and educated coordinator.
