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.

Analysis of Intestinal and Nasopharyngeal Microbiota of Children with Meningococcemia in Pediatric Intensive Care Unit: INMACS-PICU Study.

Microbiota composition might play a role in the pathophysiology and course of sepsis, and understanding its dynamics is of clinical interest. Invasive meningococcal disease (IMD) is an important cause of community-acquired serious infection, and there is no information regarding microbiota composition in children with meningococcemia. In this study, we aimed to evaluate the intestinal and nasopharyngeal microbiota composition of children with IMD. Materials and Methods: In this prospective, multi-center study, 10 children with meningococcemia and 10 age-matched healthy controls were included. Nasopharyngeal and fecal samples were obtained at admission to the intensive care unit and on the tenth day of their hospital stay. The V3 and V4 regions of the 16S rRNA gene were amplified following the 16S Metagenomic Sequencing Library Preparation. Results: Regarding the alpha diversity on the day of admission and on the tenth day at the PICU, the Shannon index was significantly lower in the IMD group compared to the control group (p = 0.002 at admission and p = 0.001, on the tenth day of PICU). A statistical difference in the stool samples was found between the IMD group at Day 0 vs. the controls in the results of the Bray-Curtis and Jaccard analyses (p = 0.005 and p = 0.001, respectively). There were differences in the intestinal microbiota composition between the children with IMD at admission and Day 10 and the healthy controls. Regarding the nasopharyngeal microbiota analysis, in the children with IMD at admission, at the genus level, Neisseria was significantly more abundant compared to the healthy children (p < 0.001). In the children with IMD at Day 10, genera Moraxella and Neisseria were decreased compared to the healthy children. In the children with IMD on Day 0, for paired samples, Moraxella, Neisseria, and Haemophilus were significantly more abundant compared to the children with IMD at Day 10. In the children with IMD at Day 10, the Moraxella and Neisseria genera were decreased, and 20 different genera were more abundant compared to Day 0. Conclusions: We first found alterations in the intestinal and nasopharyngeal microbiota composition in the children with IMD. The infection itself or the other care interventions also caused changes to the microbiota composition during the follow-up period. Understanding the interaction of microbiota with pathogens, e.g., N. meningitidis, could give us the opportunity to understand the disease's dynamics.

Attention to diseases that re-emerge due to refusal of vitamin K: an infant case.

Intramuscular vitamin K injection is recommended for all newborns to prevent bleeding. However, the number of parents who reject vitamin K is at an increase. We present a 1-month girl who presented with haemorrhagic shock due to extraordinary intra-thoracic bleeding. The patient was treated with thoracentesis and blood transfusion. Parents were informed the about the benefits of Vitamin K and they were convinced to continue a routine immunization programme.

Clinically mild encephalitis/encephalopathy with a reversible splenial lesion of the corpus callosum in childhood: a single-center experience.

BACKGROUND: Mild encephalitis/encephalopathy with a reversible splenial lesion (MERS) is a rare clinicoradiological syndrome that typically presents with central nervous system symptoms such as loss of consciousness, seizure, headache, and ophthalmoparesis. METHODS: Here, we highlight the characteristics of this syndrome together with the clinical and MRI findings of 6 pediatric patients with MERS. RESULTS: Between January 2017 and October 2020, 6 patients with MERS (3 boys and 3 girls) presented to our center. The mean age was 122 ± 54.6 (min-max: 44-180) months. None of the patients had a chronic disease. In our study, infectious agents were detected in 4 patients (66.6%), while noninfectious causes (one seizure and the other hyponatremia) were detected in two patients. All of our cases were discharged without any sequelae after an average of 12.1 ± 7 (min-max: 4-20) days of hospitalization. In 1 patient (case 6), control MRI could not be performed, and the radiological recovery of our other patients was shown to be between 14 days and 2 months. DISCUSSION: MERS is an acute encephalopathy with good prognosis and should be considered by neurologists in differential diagnosis due to its variable clinical presentation and specific MRI findings.

Epidemiology of pediatric severe sepsis and septic shock in Turkey: Prevalence, Results and Treatments Study.

AIM: This study was aimed at characterizing the prevalence, management, and outcomes of pediatric severe sepsis and septic shock in tertiary pediatric intensive care units (PICUs) in Turkey. METHODS: A point prevalence study was conducted on five days over the course of one year in 29 PICUs in Turkey. Outcomes included severe sepsis and septic shock point prevalence, therapies used, duration of PICU stay, and mortality at day 28. RESULTS: Of the 1757 children who were admitted to the PICU during the study period, 141 (8.0%) children met the consensus criteria for severe sepsis and 23 (1.3%) children met the criteria for septic shock. Pediatric severe sepsis and septic shock accounted for 8% and 1.3% of all PICU admissions, respectively. The median age of the patients was 2.6 years (interquartile range (IQR), 0.7-8.6 years). Enteral nutrition (79.3%) was preferred compared to parenteral nutrition (31.1%) for the first 3 days after PICU admission. A total of 39 patients died while in the PICU, for a 23.8% mortality rate, which did not vary by age. CONCLUSION: The mortality rate was similar to that in other studies. Hematologic-immunologic comorbidity, parenteral nutrition and the use of vasoactive drugs were independently associated with mortality.

Increased Severe Cases and New-Onset Type 1 Diabetes Among Children Presenting With Diabetic Ketoacidosis During First Year of COVID-19 Pandemic in Turkey.

Introduction: There have been some significant changes regarding healthcare utilization during the COVID-19 pandemic. Majority of the reports about the impact of the COVID-19 pandemic on diabetes care are from the first wave of the pandemic. We aim to evaluate the potential effects of the COVID-19 pandemic on the severity of diabetic ketoacidosis (DKA) and new onset Type 1 diabetes presenting with DKA, and also evaluate children with DKA and acute COVID-19 infection. Methods: This is a retrospective multi-center study among 997 children and adolescents with type 1 diabetes who were admitted with DKA to 27 pediatric intensive care units in Turkey between the first year of pandemic and pre-pandemic year. Results: The percentage of children with new-onset Type 1 diabetes presenting with DKA was higher during the COVID-19 pandemic (p < 0.0001). The incidence of severe DKA was also higher during the COVID-19 pandemic (p < 0.0001) and also higher among children with new onset Type 1 diabetes (p < 0.0001). HbA1c levels, duration of insulin infusion, and length of PICU stay were significantly higher/longer during the pandemic period. Eleven patients tested positive for SARS-CoV-2, eight were positive for new onset Type 1 diabetes, and nine tested positive for severe DKA at admission. Discussion: The frequency of new onset of Type 1 diabetes and severe cases among children with DKA during the first year of the COVID-19 pandemic. Furthermore, the cause of the increased severe presentation might be related to restrictions related to the pandemic; however, need to evaluate the potential effects of SARS-CoV-2 on the increased percentage of new onset Type 1 diabetes.

Comparison of pre-PICU and per-PICU interventions, clinical features and neurologic outcomes of motor vehicle collision trauma and other mechanisms of trauma in children.

BACKGROUND: Motor vehicle collisions (MVCs) are the number one cause of death in the pediatric age group. The aim of this study was to determine the differences between MVCs and other trauma mechanisms (OTMs) in patients who were followed up at a pediatric intensive care unit (PICU). METHODS: Data were retrospectively collected for pediatric trauma patients hospitalized at a third level PICU between 2014 and 2018. Patients have been divided into two groups as MVC and OTM. Demographic data, pre-PICU interventions (cardiopulmonary resuscitation, intubation, injury severity scores, time period before intensive care), intensive care interventions (invasive mechanical ventilation, non-invasive mechanical ventilation, need for surgery, type of surgery, need for transfusion, and inotrope therapy) were compared between two groups. Outcomes were evaluated by survival, discharge from hospital, Pediatric Cerebral Performance Cate-gory (PCPC) at discharge, tracheotomy presence, and amputation performed. RESULTS: During the 5-year study period, 135 patients were hospitalized for trauma. The injured body regions were the head and neck (61.5%), abdomen and lumbar spine (39.4%), and extremities and pelvis (36.3%). Multiple trauma was mostly seen in the MVC trauma group (p=0.001). The need for invasive mechanical ventilation and inotrope therapy was greater in the MVC group (p=0.002, 0.001 respectively). One hundred and twenty-three patients (91.1%) survived. The mortality rate was higher in the MVC group (p=0.026). The PCPC results were better in the OTM group (p=0.017). CONCLUSION: MVCs lead to more multiple trauma cases than OTMs. Invasive mechanical ventilation, inotropes, and other inten-sive care interventions were necessary much more often in MVC victims than in OTM patients.

Giant Right Atrial Myxoma with Fulminant Progression in an Infant.

Cardiac myxoma is rare in children. Myxomas are exceedingly rare in infancy. Right atrial myxomas were recorded in a small number of case reports involving infants worldwide. We report the case of a 2-month-old infant with giant right atrial myxoma. The case presented to our hospital with respiratory distress, and had pericardial and pleural effusion. Diagnosis of cardiac tumor was made with the aid of computerized tomography scan and echocardiogram. The tumor size was 3.1 × 3.4 × 3.9 cm. The patient worsened rapidly and had sudden cardiac arrest which did not respond to interventions. Postmortem cardiac autopsy confirmed the diagnosis of myxoma on gross examination and histology. This article aims to focus attention to the atypical size and location of this atrial myxoma, causing diagnostic difficulty in this infant.

Early Neurologic Complications and Long-term Neurologic Outcomes of Extracorporeal Membrane Oxygenation Performed in Children.

BACKGROUND: We aimed at evaluating acute neurologic complications (ANC) and clinical outcome at a 2-year follow-up in children after extracorporeal membrane oxygenation (ECMO). METHODS: We conducted a single-center, retrospective review of our patient cohort aged between 1 month and 18 years at the time of ECMO support (between June 2014 to January 2017). Outcome analysis included ANC and their clinical consequences.The Pediatric Overall Performance Category (POPC) and Pediatric Cerebral Performance Category (PCPC) were used for neurologic assessment performed at discharge from the hospital and at 2nd year follow-up. RESULTS: There were 35 children who required ECMO. The median ECMO time was 9 days (range 2-32 days). Decannulation from ECMO was achieved in 68.6% of patients, and overall, 42.8% survived (15 patients), The incidence of ANC in the surviving patients was 40% (6 children). ANC were intracranial hemorrhage, seizures, cerebral infarction, which occurred in one, two and three of the 15 surviving patients respectively (6.6, 13.3 and 20%). A higher rate of organ failure was related to death (p=0.043), whereas duration on ECMO was a risk factor for the development of ANC (p<0.05). At hospital discharge, the 14 patients evaluated had normal development or -mild disability in 73.2%, and at the 2-year follow-up, 93.4% had these scores. CONCLUSION: Children who receive ECMO have a risk to develop ANC, which was related to the length of ECMO treatment, while survival was related to less organ failure, Long-term neurological outcome was good in our patient cohort.

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.

A Case of Pulmonary Artery Sling Anomaly with Tracheal Stenosis and Management of Difficult Airway.

Pulmonary artery sling is a rare congenital vascular abnormality, where the left pulmonary artery originates from the right pulmonary artery, passes between trachea, and esophagus and reaching the left hilum. Cough, wheezing, and difficulty in feeding are three major symptoms. Untreated pulmonary sling carries high morbidity and mortality, most of which is due to the airway and other associated anomalies. Herein, we reported a 40-day-old male infant who admitted to the pediatric intensive care unit with progressive respiratory distress and diagnosed with left pulmonary sling with tracheal stenosis. We discussed the diagnosis and management of pulmonary artery sling and present the successful use of laryngeal mask in difficult airway management.

Overlap Stevens Johnson Syndrome/Toxic Epidermal Necrolysis developed due to the use of toxic-dose vinblastine in case of Langerhans Cell Histiocytosis(Letterer-Siwe).

Except for side effects expected standart dose use of the chemotherapeutics agents, toxic effects (poisoning) may occur if high doses of are mistakenly used in the treatment of haemato-oncological diseases and these toxic doses are usually fatal. Here, we report a case of Stevens Johnson Syndrome (SJS) / Toxic Epidermal Necrolysis (TEN) following administration of toxic dose of vinblastine by mistake. A 20-month-old male patient with a diagnosis of Langerhans Cell Histiocytosis (Letterer-Siwe) at the pediatric oncology department was admitted to intensive care unit, after having received treatment protocol consisting of vinblastine, etoposide and prednisolone, with fever, altered consciousness and decompensated shock findings. Skin biopsy which performed from bullous lesions in the perianal, neck and axillary regions was resulted compatible with SJS / TEN in the patient with multiple organ failure, at 48 h of admission. It was later determined that the patient has been mistakenly given 10 times the normal dose of vinblastine he needed (60 mg/m2), which was 6 mg/m2. Plasma exchange was performed 3 times for vinblastine toxicity, intravenous immunoglobulin was administered for SJS / TEN therapy and phenobarbital was initiated to increase drug metabolism. The patient whose clinical picture fully improved, was transferred to the oncology department on the 30th day of intensive care hospitalization. Vinblastine toxicity is a life-threatening condition that can cause multiple organ failure, SJS / TEN. Plasma exchange is an effective treatment method for the removal of vinblastine from the body and in these cases of toxicity.

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.

Pseudomonas Aeruginosa Sepsis in a Previously Healthy Infant with Subcutaneous Nodules and Mastoid Bone Destruction.

Pseudomonas aeruginosa septicemia is rare in previously healthy children. Skin lesions such as subcutaneous nodules and ecthyma gangrenosum may be the first manifestation of Pseudomonas infection that have rarely been reported. Herein we reported a previously healthy 6-month-old boy patient who presented with suppurative otitis media, multiple nodules, septic shock, and P. aeruginosa was identified in cultures of the blood, skin lesions, and purulent material of his ears.

Acute necrotizing encephalopathy of childhood: a single-center experience

Background/aim: Acute necrotizing encephalopathy is a rare type of acute encephalopathy characterized by multi-ocal brain lesions and associated severe neurological findings and various organ dysfunctions may accompany it. Materials and Methods: Patients with acute necrotizing encephalopathy of childhood diagnosed by pediatric neurology and pediatric intensive care at Sami Ulus Maternity, Child Health and Diseases Training and Research Hospital between 2007 and 2020 were included in this study. Results: Nine patients (six females, three males) with a mean age of 4.05 ± 1.94 years (age range 1­6.5) were included in this study. The interval range between fever and encephalopathy in patients was 1­4 days. Influenza A (3H1N1, one untyped) was detected in four patients, influenza B in three patients, and no cause was found in two patients. Major clinical findings other than febrile encephalopathy in all patients were a hemodynamic shock in seven patients, seizures in six patients, vomiting in five patients, dystonia in three patients, and flaccid paralysis in the upper extremity in one patient. Despite all our treatment approaches, including plasmapheresis, moderate to severe neurological sequelae was observed in all of our patients, who survived even with significant radiological improvement. Three patients for whom we could not perform plasmapheresis died. Conclusion: Our study revealed that thalamic involvement increased as the interval shortened, and brainstem involvement increased in patients over four years of age. The presence of persistent vomiting accompanying encephalopathy during the parainfectious period and plasmapheresis treatment being a treatment option that could prevent mortality were cautionary for our study.
