Comparison of early characteristics of multisystemic inflammatory syndrome and Kawasaki disease in children and the course of Kawasaki disease in the pandemic.

INTRODUCTION: Multisystemic inflammatory syndrome (MIS-C) is a newly described disease manifestation in children associated with the novel coronavirus SARS-CoV-2 infection and can be easily confused with Kawasaki disease with its clinical and laboratory findings. In this study, the clinical findings, organ involvements, similarities, and differences in laboratory and imaging of the children with MIS-C and KD at the time of admission will be revealed in detail, and the treatment methods and follow-up results will be revealed. MATERIAL AND METHOD: Our study was a single-center study and included pediatric patients who were treated with a diagnosis of MIS-C between March 2020 and July 2023 in the pediatric cardiology, pediatric emergency, pediatric infection, and pediatric intensive care clinics at Celal Bayar University and who were treated with a diagnosis of KD (complete/incomplete) between January 2015 and July 2023. MIS-C diagnosis was made according to the Turkish Ministry of Health COVID-19 guidelines. Sociodemographic characteristics, clinical, laboratory, and echocardiography findings, treatments given, and clinical course of all patients included in the study were evaluated. RESULTS: The median age was 30 months (7-84) in KD and 96 months (6-204) in MIS-C, and it was significantly higher in the MIS-C group (p = 0.000). Symptom duration was significantly longer in the MIS-C group (p = 0.000). In terms of clinical features, gastrointestinal syndrome findings (nausea, vomiting, abdominal pain) and respiratory findings (dyspnea) were significantly higher in the MIS-C group (p = 0.007, p = 0.000, p = 0.002, respectively). Regarding cardiovascular system involvement, coronary involvement was significantly higher in the KD group. However, valvular involvement, left ventricular systolic dysfunction, and pericardial effusion were significantly higher in the MIS-C group (p = 0.000, p = 0.001, p = 0.003, p = 0.023, respectively). In terms of laboratory findings, white blood cell count was higher in KD (p = 0.000), absolute lymphocyte count, platelet level, blood sodium, and albumin levels were lower in MIS-C group (p = 0.000, p = 0.000, p = 0.000, p = 0.000, p = 0.003, respectively), ferritin and troponin levels were significantly higher in MIS-C group. These results were statistically significant (p = 0.000, p = 0.000, respectively). D-dimer and fibrinogen levels were high in both groups, and no significant statistical difference was detected between the two groups. There was no significant difference between the two groups regarding the length of hospitalization and mortality, but steroid use was significantly higher in the MIS-C group (p = 0.000). CONCLUSION: In conclusion, this study has demonstrated the similarities and differences between MIS-C and KD regarding clinical findings, organ involvement, and laboratory and imaging results. The results of our study have important implications in terms of contributing to the data in the existing literature on these two diseases and for the correct diagnosis and better management of pediatric patients presenting with these disorders. WHAT IS KNOWN: Multisystemic inflammatory syndrome (MIS-C) is a newly described disease manifestation in children associated with the novel coronavirus SARS-CoV-2 infection and can be easily confused with Kawasaki disease with its clinical and laboratory findings. WHAT IS NEW: Although MIS-C and KD have many similarities, their symptoms, disease processes, possible complications, and treatment regimens may differ.

The Use of Point-of-Care Ultrasound in Pediatric Emergency Departments and Intensive Care Units: A Descriptive Study From Turkey.

OBJECTIVES: The aim was to evaluate the current status of point-of-care ultrasound (POCUS), perceptions, education, training, and barriers to using POCUS in pediatric emergency departments (PEDs) and pediatric intensive care units (PICUs) in Turkey. METHODS: A descriptive, multicenter, cross-sectional study through an online survey was developed using the REDCap online platform. The survey was distributed through the Turkish Society of Pediatric Emergency and Intensive Care e-mail group. Each survey was answered only once by each PED/PICU and by the clinical chief of the department. RESULTS: A total of 19 PEDs and 26 PICUs responded to the survey. Among them, 84.2% of PEDs and 100% of PICUs reported the clinical use of POCUS. For diagnostic applications, the most common areas for PEDs and PICUs were thoracic (93.7%/100%) and cardiovascular (62.5%/65.4%) assessment, and in the procedural use of POCUS, the most frequent applications were those for vascular access (75.0%/92.3%) and thoracentesis (31.2%/65.4%). The most commonly reported clinical benefits were rapid diagnosis, rapid treatment, and decreased complications during procedural applications for PEDs and PICUs. Evaluating the barriers to POCUS use in PEDs and PICUs, the most common reasons for insufficient use were the lack of ultrasound machines and/or equipment, a shortage of manpower, lack of awareness, and lack of training. For PEDs (68.4%) and for PICUs (84.6%), participants agreed that POCUS training should be mandatory during fellowship programs. CONCLUSIONS: Most participants were aware of the need for POCUS. However, lack of education, equipment, manpower, and infrastructure still emerged as barriers to the use of POCUS. To further promote POCUS use, it would be helpful to improve accessibility by ensuring sufficient numbers of ultrasound devices together with sufficient numbers of appointed physicians and by expanding POCUS education in PEDs and PICUs.

[Seasonal Trends and Interactions of Viral Pathogens in Children Presenting with Acute Respiratory Tract Infections in the Advancing Periods of SARS-CoV-2 Pandemic]. / SARS-CoV-2 Pandemisinin Ilerleyen Dönemlerinde Akut Solunum Yolu Enfeksiyonu ile Basvuran Çocuklarda Viral Patojenlerin Mevsimsel Egilimleri ve Etkilesimleri.

Although various bacteria and viruses have been identified in the etiology of acute respiratory tract infections (ARI), 90% of acute ARIs that develop in children are of viral origin. The aim of this study was to investigate the seasonal trends and interactions between infectious agents and to determine the risk factors associated with ARI in children aged 1-15 years admitted to the Pediatric Emergency Department of Manisa Celal Bayar University Hospital in the advancing periods of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic. To determine the bacterial and viral agents, samples were taken from 314 patients attending to the hospital with symptoms suggestive for ARI, between 06/01/2021 and 05/31/2022. Viral and bacterial agents were identified by multiplex polymerase chain reaction (PCR) and automated identification system, respectively. Demographic data of the participants and possible risk factors for ARI were recorded in the questionnaires. In the study, viral agents were detected in 77.3% of the children, and the most common infectious agent was rhinovirus/enterovirus (RV/EV) (36.3%), followed by influenza viruses (11.2%), and SARS-CoV-2 (10.5%). While RV/EV positivity was found to be higher in children with moderate and below average (p< 0.001) hand hygiene, influenza positivity was found higher in those attending school/preschool institution (p< 0.001) and whose mothers working full-time (p< 0.001). Respiratory syncytial virus positivity was associated with maternal smoking (p= 0.013) and home overcrowding (p= 0.014). Bacterial colonization was detected in 33 (11.6%) of 284 children whose swabs were taken for both bacterial and viral agents and the most frequently detected agents were Staphylococcus aureus (60.6%) and Pseudomonas aeruginosa (15.2%). Having siblings (p= 0.008) and maternal smoking (p= 0.012) were found to be associated with the detection of bacterial agents. In this study, in the advanced period of the pandemic, the most detected agents and seasonal characteristics were found to be similar to the pre-pandemic period. It is thought that knowing the regional etiology and risk factors will contribute to taking the necessary local control and protective measures.

COVID-19 Disease in Presenting to the Pediatric Emergency Department: A Multicenter Study of 8886 Cases.

BACKGROUND: The aim was to evaluate the epidemiological, clinical, laboratory, and radiologic data of children with SARS-CoV-2 positivity by polymerase chain reaction (PCR) together with treatment strategies and clinical outcomes and to evaluate cases of multisystem inflammatory syndrome in children (MIS-C) in this population. METHODS: This was a multicenter retrospective observational cohort study performed in the pediatric emergency departments of 19 tertiary hospitals. From March 11, 2020, to May 31, 2021, children who were diagnosed with confirmed nasopharyngeal/tracheal specimen SARS-CoV-2 PCR positivity or positivity for serum-specific antibodies against SARS-CoV-2 were included. Demographics, presence of chronic illness, symptoms, history of contact with SARS-CoV-2 PCR-positive individuals, laboratory and radiologic investigations, clinical severity, hospital admissions, and prognosis were recorded. RESULTS: A total of 8886 cases were included. While 8799 (99.0%) cases resulted in a diagnosis of SARS-CoV-2 with PCR positivity, 87 (1.0%) patients were diagnosed with MIS-C. Among SARS-CoV-2 PCR-positive patients, 51.0% were male and 8.5% had chronic illnesses. The median age was 11.6 years (IQR: 5.0-15.4) and 737 (8.4%) patients were aged <1 year. Of the patients, 15.5% were asymptomatic. The most common symptoms were fever (48.5%) and cough (30.7%) for all age groups. There was a decrease in the rate of fever as age increased (p < 0.001); the most common age group for this symptom was <1 year with the rate of 69.6%. There was known contact with a SARS-CoV-2 PCR-positive individual in 67.3% of the cases, with household contacts in 71.3% of those cases. In terms of clinical severity, 83 (0.9%) patients were in the severe-critical group. There was hospital admission in 1269 (14.4%) cases, with 106 (1.2%) of those patients being admitted to the pediatric intensive care unit (PICU). Among patients with MIS-C, 60.9% were male and the median age was 6.4 years (IQR: 3.9-10.4). Twelve (13.7%) patients presented with shock. There was hospital admission in 89.7% of these cases, with 29.9% of the patients with MIS-C being admitted to the PICU. CONCLUSION: Most SARS-CoV-2 PCR-positive patients presented with a mild clinical course. Although rare, MIS-C emerges as a serious consequence with frequent PICU admission. Further understanding of the characteristics of COVID-19 disease could provide insights and guide the development of therapeutic strategies for target groups.

Noninvasive Hemoglobin Measurement Reduce Invasive Procedures in Thalassemia Patients.

This study was conducted to investigate the agreement between laboratory hemoglobin (LabHb) measured in venous blood and noninvasive, spectrophotometric hemoglobin (SpHb) measurement and the usability of SpHb measurement in the transfusion decision-making in patients with thalassemia whose hemoglobin (Hb) was monitored by taking blood samples at frequent intervals and who were transfused. Cardiac pulse, oxygen saturation, Pleth variability index (PVI), and SpHb values were measured in patients who came to the hematology outpatient clinic for a control visit and whose Hb levels were planned to be measured. Venous blood samples were taken for LabHb measurement, which we accept as the gold standard. Cohen's kappa value was calculated for the agreement between SpHb measurements and LabHb values. The relationship and predictability between both measurement methods were evaluated by Pearson correlation analysis, a modified Bland-Altman plot and the linear regression model. In the study conducted with a total of 110 children with thalassemia, a moderate level of agreement between the two measurement methods (kappa = 0.370, p < 0.0001) and a significantly high correlation between the two tests (r = 0.675) were found. The mean bias between the differences was found to be 0.3 g/dL (-1.27 to 1.86 g/dL). The sensitivity and the specificity of SpHb in identifying patients who needed transfusions (Hb <10.0 g/dL) were calculated as 92.2 and 57.1%, respectively. Our results suggest SpHb measurement may be used to screen anemia in hemodynamically stable hemoglobinopathy patients and even for transfusion decision-making with combination clinical findings.

The skills of defibrillation practice and certified life-support training in the healthcare providers in Turkey.

AIM OF THE STUDY: Successful cardiopulmonary resuscitation and early defibrillation are critical in survival after in- or out-of-hospital cardiopulmonary arrest. The scope of this multi-centre study is to (a) assess skills of paediatric healthcare providers (HCPs) concerning two domains: (1) recognising rhythm abnormalities and (2) the use of defibrillator devices, and (b) to evaluate the impact of certified basic-life-support (BLS) and advanced-life-support (ALS) training to offer solutions for quality of improvement in several paediatric emergency cares and intensive care settings of Turkey. METHODS: This cross-sectional and multi-centre survey study included several paediatric emergency care and intensive care settings from different regions of Turkey. RESULTS: A total of 716 HCPs participated in the study (physicians: 69.4%, healthcare staff: 30.6%). The median age was 29 (27-33) years. Certified BLS-ALS training was received in 61% (n = 303/497) of the physicians and 45.2% (n = 99/219) of the non-physician healthcare staff (P < .001). The length of professional experience had favourable outcome towards an increased self-confidence in the physicians (P < .01, P < .001). Both physicians and non-physician healthcare staff improved their theoretical knowledge in the practice of synchronised cardioversion defibrillation (P < .001, P < .001). Non-certified healthcare providers were less likely to manage the initial doses of synchronised cardioversion and defibrillation: the correct responses remained at 32.5% and 9.2% for synchronised cardioversion and 44.8% and 16.7% for defibrillation in the physicians and healthcare staff, respectively. The indications for defibrillation were correctly answered in the physicians who had acquired a certificate of BLS-ALS training (P = .047, P = .003). CONCLUSIONS: The professional experience is significant in the correct use of a defibrillator and related procedures. Given the importance of early defibrillation in survival, the importance and proper use of defibrillators should be emphasised in Certified BLS-ALS programmes. Certified BLS-ALS programmes increase the level of knowledge and self-confidence towards synchronised cardioversion-defibrillation procedures.

The Evaluation of Trauma Care: The Comparison of 2 High-Level Pediatric Emergency Departments in the United States and Turkey.

OBJECTIVE: The purpose of the study is to compare the outcomes of pediatric trauma patients with motor vehicle crashes (MVCs) and motor vehicle versus pedestrian crashes (MPCs) at a level 1 pediatric trauma center in the United States and a pediatric trauma center in Turkey. METHODS: The medical records of all pediatric MVC and MPC subjects presenting to the emergency departments (EDs) of a level 3 hospital in Turkey (Izmir Tepecik Training and Research Hospital [ITTRH]) and a level 1 pediatric trauma center in the United States (Children's Medical Center Dallas [CMCD]) over a 1-year period were reviewed. Data that were collected include patient demographics, prehospital report (mechanism of injury, mode of transportation), injury severity score (ISS), abbreviated injury scale score, Glasgow Coma Scale score, ED length of stay, ED interventions, ED and hospital disposition, and mortality. Patients with moderate (ISS, 5-15) and severe (ISS, >15) trauma scores were included in the study. RESULTS: One hundred six patient charts from the ITTRH and 125 patient charts from the CMCD with moderate and severe ISS due to MVCs and MPCs were reviewed. Most of the patients were pedestrians (86%) in the ITTRH group and passengers (60%) in the CMCD group. The percentage of patients transferred by ambulance (ground or air) to the CMCD and the ITTRH was 97.9% and 85%, respectively. Fifteen percent of ITTRH patients and 2.1% of CMCD patients arrived by private vehicle. Emergency department arrival ISS and Glasgow Coma Scale were similar between the 2 hospitals (P > 0.05). The overall mortality rate in the study population was 8.8% (11/125) at the CMCD and 4.7% (5/106) at the ITTRH. (P = 0.223). Blood product utilization was significantly higher in the CMCD group compared with the ITTRH group (P = 0.005). The use of hypertonic saline/mannitol/hyperventilation in patients with significant head trauma and increased intracranial pressure was higher in the ITTRH group (P = 0.000). CONCLUSIONS: This is the first study that compared pediatric trauma care and outcome at a level 1 pediatric trauma center in the United States and a pediatric hospital in Turkey. Our findings highlight the opportunities to improve pediatric trauma care in Turkey. Specifically, there is a need for national trauma registries, enhanced trauma education, and standardized trauma patient care protocols. In addition, efforts should be directed toward improving prehospital care through better integration within the health care system and physician participation in educating prehospital providers. Data and organized trauma care will be instrumental in system-wide improvement and developing appropriate injury-prevention strategies.

Importance of Clinical Decision Making by Experienced Pediatric Surgeons When Children Are Suspected of Having Acute Appendicitis: The Reality in a High-Volume Pediatric Emergency Department.

OBJECTIVE: The aim of the present study was to compare the pediatric appendicitis score (PAS), the Alvarado score (AS), white blood cell count (WBC), absolute neutrophil count (ANC), C-reactive protein (CRP) level, procalcitonin level, and ultrasound (US) data, with the appendectomy decisions of pediatric surgeons diagnosing acute appendicitis (AA) in a real-life setting; this was a top-level, high-volume pediatric emergency department (PED) in a developing country. METHODS: The study was conducted prospectively between January 2012 and June 2013 in the PED of the Tepecik Teaching and Research Hospital in Izmir, Turkey. The study was observational in nature; no attempt was made to influence indications for exploration or the timing thereof. Children aged 4 to 18 years presenting to the PED on suspicion of AA were included. The WBC, ANC, CRP level, and procalcitonin level were measured, and US was performed on all patients on admission. The PAS and AS were calculated. An operative decision was made by each pediatric surgeon who had the results of laboratory and radiological tests. The criterion standard for AA was histopathological assessment. RESULTS: Upon receiver operating curve (ROC) analysis, the areas under the ROCs (AUROCs) of the WBC, ANC, CRP level, procalcitonin level, US positivity, PAS, AS, and decisions of pediatric surgeons supported by laboratory and US data were 0.734, 0.741, 0.671, 0.675, 0.670, 0.831, 0.794, and 0.910, respectively. When US data were employed only in cases with PASs 4 to 7, the sensitivity increased but specificity decreased. The sensitivity and specificity of pediatric surgical decisions were 100% and 82.50%, respectively. The difference between the PAS AUROC and the pediatric surgeon decision-making AUROC was significant (P = 0.0393; 95% confidence interval, 0.0470-0.226). CONCLUSIONS: Good pediatric surgical decision making supported by laboratory and US data for those suspected of AA may be the most effective diagnostic tool in a high-volume PED in a developing country.

A Rare Cause of Metabolic Acidosis: Fatal Transdermal Methanol Intoxication in an Infant.

Oral methanol intoxication is common, but dermal intoxication is rare. We report a previously healthy 19-month-old female infant admitted to the emergency department (ED) with vomiting and tonic-clonic seizure. On physical examination, she was comatose and presented signs of decompensated shock with Kussmaul breathing. Her left thigh was edematous, with purple coloration. Methanol intoxication was suspected due to high anion gap metabolic acidosis (pH, 6.89; HCO3, <3 meq/L) and exposure to spirit-soaked bandages (%96 methanol) for 24 hours and 3 days. The patient's serum methanol level was 20.4 mg/dL. She was treated with fomepizole and continuous venovenous hemodialysis (CVVHD) in the pediatric intensive care unit, and methanol levels decreased to 0 mg/dL after 12 hours. During follow-up, massive edema and subarachnoid hemorrhage in the occipital lobe were detected by computed tomography of the brain. The patient died after 7 days.Although methanol intoxication occurs predominantly in adults, it must be considered in children with high-anion gap metabolic acidosis. This case report demonstrates that fatal transdermal methanol intoxication can occur in children, and it is the second report in the English literature of transdermal methanol intoxication in an infant.

Factors affecting the decision to hospitalise children admitted to the emergency department due to non-fatal suicide attempts by pills.

OBJECTIVE: Suicide attempts (SAs) in the paediatric age group represent an important cause of morbidity and mortality. Our aim was to examine the factors affecting the decision to hospitalize children with a diagnosis of non-fatal SA by pills. METHODS: Children <18 years of age admitted with SA by pills during 2014 were evaluated retrospectively. Patients were divided into two groups: Group-I comprised hospitalised patients and Group-II included those who were discharged from the PED. These two groups were compared in terms of clinical and demographic characteristics recorded upon PED admission. RESULTS: A total of 196 patients were included in the study. The number of pills taken for self-poisoning in Group-I (median: 20 pills) was higher than that in Group-II (median: 12 pills) (p < 0.001), and the rate of pathological findings during the first paediatric psychiatric consultation was higher in Group-I (91.1%) than in the Group-II (54.8%) (p < 0.001). CONCLUSION: Factors affecting the disposition decision in cases of children who performed non-fatal SA via pills included the amount of medication taken for the suicide attempt and the presence of psychiatric disorders, as determined by a paediatric psychiatrist during the acute phase.

The importance of microalbuminuria in predicting patient outcome in a PICU.

OBJECTIVE: To evaluate the prognostic significance of microalbuminuria in critically ill children. DESIGN: Prospective study. SETTING: PICU of a teaching hospital. PATIENTS: Admitted critically ill children. INTERVENTIONS: The urine albumin-creatinine ratio was measured at admission and at 24 hours. Pediatric Risk of Mortality, Pediatric Index of Mortality II, Pediatric Logistic Organ Dysfunction, and Inotrope Score were calculated. MEASUREMENTS AND MAIN RESULTS: In total, 102 patients (median age, 19 mo) were included in the study, among whom were 30 mortalities. Microalbuminuria was identified in 62 patients (64%). The patients were classified into three groups: patients with sepsis, patients with noninfectious systemic inflammatory response syndrome, and patients without systemic inflammatory response syndrome. The highest clinical scores, albumin-creatinine ratio levels, mortality rate, and duration of mechanical ventilation were found in the sepsis group, and the lowest values were seen in patients without systemic inflammatory response syndrome (p < 0.05). Significant correlations were observed between the albumin-creatinine ratio levels and the clinical scores (p < 0.05). The receiver operating characteristics curve analysis showed that the areas under the curves were 0.818 and 0.781, respectively, for albumin-creatinine ratio measured at admission and at 24 hours to identify PICU mortality. At a cutoff value of 34.2 mg/g, albumin-creatinine ratio measured at admission may be able to discriminate between patients a with sensitivity of 63.3%, specificity of 93.3%, positive predictive value of 95%, and negative predictive value of 56%. CONCLUSIONS: Microalbuminuria is a simple, inexpensive, and useful tool for predicting mortality and morbidity in critically ill children in the PICU.

A single-center experience on percutaneously performed partial omentectomy in pediatric peritoneal dialysis patients.

OBJECTIVE: This study describes a single-center experience on percutaneously performed partial omentectomy procedure in pediatric peritoneal dialysis (PD) patients who showed early catheter dysfunction and required catheter replacement due to catheter flow obstruction. MATERIALS AND METHODS: We performed a retrospective review of clinical outcomes from pediatric PD patients who underwent percutaneous catheter replacement by pediatric nephrologists between November 1995 and December 2012. Partial omentectomy was performed in those patients in whom omental or adhesion trapping to the catheter tip was seen. RESULTS: During the study period, catheter dysfunction that eventually required percutaneous catheter replacement occurred in 32 (23.7%) children. Of these, 9 patients were performed partial omentectomy. Mean age at initiation of PD and time of omentectomy was 97.48 ± 46.06 and 98.53 ± 45.55 months, respectively. Catheter dysfunction appeared after a mean 1.20 ± 1.0 months. The causes of catheter dysfunction were omental wrapping and malposition. No peritonitis occurred before omentectomy. Mean total operation time was 60 ± 8.83 min. No complications were encountered during the procedure. After omentectomy, mean catheter survival period was 5.92 ± 6.88 months. A total of five peritonitis episodes occurred. Three patients were transferred to hemodialysis. Six patients were on PD treatment without any problem at the end of the first year of their follow-up. Two patients underwent kidney transplantation. Four patients were still on chronic PD treatment at the end of the study period. CONCLUSION: When performed by an experienced nephrologist, the performance of partial omentectomy by percutaneous route, when required, is an easy, safe and efficient therapeutic procedure in children on chronic PD treatment.

A deep learning feature extraction-based hybrid approach for detecting pediatric pneumonia in chest X-ray images.

Pneumonia is a disease caused by bacteria, viruses, and fungi that settle in the alveolar sacs of the lungs and can lead to serious health complications in humans. Early detection of pneumonia is necessary for early treatment to manage and cure the disease. Recently, machine learning-based pneumonia detection methods have focused on pneumonia in adults. Machine learning relies on manual feature engineering, whereas deep learning can automatically detect and extract features from data. This study proposes a deep learning feature extraction-based hybrid approach that combines deep learning and machine learning to detect pediatric pneumonia, which is difficult to standardize. The proposed hybrid approach enhances the accuracy of detecting pediatric pneumonia and simplifies the approach by eliminating the requirement for advanced feature extraction. The experiments indicate that the hybrid approach using a Medium Neural Network based on AlexNet feature extraction achieved a 97.9% accuracy rate and 98.0% sensitivity rate. The results show that the proposed approach achieved higher accuracy rates than state-of-the-art approaches.

Adolescents With Breakthrough COVID-19 Infections Requiring Hospitalization: A Multicenter Retrospective Study.

Background Vaccines have the most important role in the battle against the COVID-19 pandemic. With the widespread use of vaccines, COVID-19 has remarkably declined. Adolescents were vaccinated after approvals for this age group, which was later than adults, and a nationwide vaccination program was implemented in August 2021 in Turkey for adolescents ≥12 years of age. Therefore, we aimed to determine the effects of the COVID-19 nationwide adolescent vaccination program on adolescent hospitalizations due to COVID-19 and multisystem inflammatory syndrome in children (MIS-C) by comparing two periods, including the vaccination period (VP) and the pre-VP (PVP). The second aim of this study is to compare the clinical features and disease severity of vaccine-breakthrough COVID-19 hospitalizations with unvaccinated individuals in the VP. Methods A retrospective multicenter study was conducted to determine and compare the number of hospitalizations due to COVID-19 and MIS-C between the VP (September 1, 2021, to August 31, 2022) and PVP (September 1, 2020, to August 31, 2021). We also compared the characteristics, risk factors, and outcomes of breakthrough infections of adolescents aged 12-18, which required hospitalization with the same age group of unvaccinated hospitalized individuals during the VP. Results During the study period, 3967 children (0-18 years) were hospitalized in the PVP and 5143 (0-18 years) in the VP. Of them, 35.4% were adolescents (12-18 years) in the PVP, and this rate was 18.6% in the VP; relative risk was 0.6467 (95% confidence interval [CI]: 0.6058-0.6904; p < 0.001). Patients with breakthrough COVID-19 were older (201 vs. 175 months, p < 0.001) and less commonly hospitalized for COVID-19 (81.5% vs. 60.4%, p < 0.001, odds ratio [OR]: 0.347 [95% CI: 0.184-0.654]). The majority of these infections were asymptomatic and mild (32% vs.72.9%: p < 0.001, OR: 5.718 [95% CI: 2.920-11.200]), and PICU admission was less frequently required (p = 0.011, OR: 0.188 [95% CI: 0.045-0.793]). Most breakthrough COVID-19 infections occurred within three months after the last vaccine dose (54.2%). Conclusions This study demonstrated a significant decrease in adolescent hospitalizations due to COVID-19 and MIS-C after implementing COVID-19 vaccines in Turkey. Breakthrough cases were less severe and mostly occurred three months after the last dose. This study emphasizes the importance of COVID-19 vaccines and that parents' decisions may be changed, particularly those who hesitate to or refuse vaccination.

Severe renal osteodystrophy in a pediatric patient with end-stage renal disease: Sagliker syndrome?

Renal osteodystrophy (ROD) is a multifactorial disorder of bone metabolism in chronic kidney disease (CKD). As CKD progresses, ensuing abnormalities in vitamin D metabolism and parathyroid hormone (PTH) secretion result in distortions in trabecular microarchitecture, thinning of the cortical shell, and increased cortical porosity. The recently described Sagliker syndrome (SS) might be an exaggerated version of ROD and is a very striking and prominent feature of secondary hyperparathyroidism in patients with end-stage renal disease (ESRD). It includes a distorted facial appearance, short stature, extremely severe maxillary and mandibulary changes, soft tissue tumors in the mouth, teeth/dental abnormalities, fingertip changes, knee and scapula deformities, hearing abnormalities, and neurologic and psychological problems. We herein describe an affected 14-year-old girl with severe ROD resulting from ESRD, who had severe peripheral and central neurologic problems caused by bone deformities, mimicking the features of Sagliker syndrome.

The effect of circumcision on the frequency of urinary tract infection, growth and nutrition status in infants with antenatal hydronephrosis.

The objective of this study was to determine the effect of circumcision on the frequency of urinary tract infection (UTI), growth development, and the nutrition status in infants with antenatal hydronephrosis (AH). The data were collected prospectively between 1998 and 2010. Infants with a fetal pelvis diameter of >5 mm identified with antenatal ultrasound were followed-up. Body height and weight were expressed as HZ scores (observed height - median height/standard deviation) and WZ scores (observed weight - median weight/Standard deviation). The nutritional status was evaluated and the body weight was transformed to a weight-for-height index (WHI = weight/median weight for the height age × 100). The HZ and WZ scores or WHI were calculated for each patient at the first and last visits. The chi-square and Student's t tests were used for statistical analysis. A p value <0.05 was considered significant. The study included 178 (134 males, 44 females) patients. Of these, 29 were diagnosed by vesicoureteral reflux (VUR), 87 by obstructive uropathy, and 54 by normal. Of 134 males, 111 infants were circumcised. The mean monitoring time was 45±24.9 months and the mean age of circumcision was 14 ± 16.06 months. The pre-circumcision UTI frequency (2.97 ± 1.14/y) was significantly higher than post-circumcision period (0.25 ± 0.67/y) (p < 0.05). Also, pre-circumcision UTI frequency (2.97 ± 1.14/y) was significantly higher than the UTI frequency observed in female cases (0.85 ± 0.91/y) and in the overall study group (0.73 ± 0.79/y) (p < 0.05). In all patients, the HZ of the circumcised subjects (0.18 ± 1.01) was statistically higher than uncircumcised subjects (-0.26 ± 0.92) (p < 0.05). Although statistically insignificant, the HZ of the circumcised males (0.13 ± 1.24) with VUR was higher than the uncircumcised patients (0.03 ± 0.55) (p > 0.05). In obstructive uropathy groups, the HZ of the circumcised males (-0.13 ± 0.54) was also found to be higher than uncircumcised males (-0.49 ± 0.66) (p < 0.05). Although nutrition scores were found to be better in circumcised males, no statistically significant effect of circumcision on the nutrition status was detected. In conclusion, postnatal early circumcision of infants with AH seems to prevent frequent UTIs and nutritional disturbances enabling normal growth.

The performance of acute peritoneal dialysis treatment in neonatal period.

The aim of this retrospective study was to evaluate our neonatal intensive care unit (NICU) patients' characteristics treated with acute peritoneal dialysis (PD) and their risk factors for mortality. We also wanted to share our experience of the application of PD in neonates who required less than 60 mL of dwell volume and their PD-related problems, as well as special solutions for these problems. This study included 27 infants treated in our NICU between February 2008 and December 2011. We retrospectively analyzed these patients' records. The percutaneous PD catheter was placed by us. PD procedure was performed either by manual technique or automated PD. Statistical evaluation was performed by using χ(2)-tests and Student's t-tests. In these 27 neonates, the average gestational age and birth weight were 35.18 ± 4.02 weeks and 2534.62 ± 897.41 g, respectively. The mean PD duration time was 6.11 ± 6.30 days. Of these, 10 patients were treated by manual technique, whereas 17 patients were treated with automated system. Among 27 neonates, 16 patients died. Overall mortality rate was 59.25%. PD-related complications were seen in 25.92% of patients. In conclusion, PD application is less effective and troublesome for low-birth-weight infants. Each center should create its own solutions to accommodate problematic patients in PD treatment to improve the outcome in this special population.

Characteristics and outcomes of critically ill children transported by ambulance in a Turkish prehospital system: a multicenter prospective cohort study.

BACKGROUND: The most underdeveloped area in the care of critically-ill-children (CIC) is the prehospital period. Appropriate prehospital assessment and life-saving-interventions (LSI) of this population are challenging and require dedicated resources to ensure the best outcomes. We aimed to determine the characteristics and outcomes of CIC transported to the Turkish Pediatric Emergency Departments (EDs). The frequency and distribution of LSI administered by prehospital providers on route and in the EDs were also investigated. METHODS: This prospective study was conducted at 4 metropolitan cities and 9 tertiary pediatric EDs between August 2014-August 2015. A survey based study evaluated all CIC who were brought by ambulance to the participant EDs. CIC were defined as a patient who requires LSI or needs intensive care admission for any reason. Patient demographics, clinical features, reason for transport, performed procedures in the ambulance or ED were sought. Finally, the short-term outcomes of transported CIC and transport-associated risks were analyzed. RESULTS: During the study period, a total 2094 children were brought by ambulance to all participant EDs. Only 227 (10.8%) of them were critically-ill. Emergency Medical Services (EMS) providers were less likely to perform procedures in CIC if they were staffed with paramedics (p < 0.001). Most procedures were performed on children aged one or older (p < 0.001). No procedure was performed in the ambulance for nearly one fourth of patients who received LSI in the EDs. If the EMS did not have a physician, prehospital providers were less likely to provide immediate LSIs (p < 0.001). CIC were more likely referred from secondary/tertiary care hospitals. The short-term mortality rate was higher if the ambulance was staffed by only paramedics. CONCLUSION: This study demonstrated that Turkish prehospital pediatric emergency care is deficient. We offer a clinical overview of pediatric emergencies to aid EMS directors, policymakers, and ED directors in planning the care of CIC.

Henoch-Schönlein purpura in children from western Turkey: a retrospective analysis of 430 cases.

The medical records of children discharged with a diagnosis of Henoch-Schönlein purpura (HSP) between January 1996 and March 2006 were analyzed retrospectively. The patient population consisted of 430 children (225 boys, mean age: 7.9 +/- 2.9 years; range: 2-14 years). At onset, purpura was present in all cases, arthritis/arthralgias in 195 (45.3%), abdominal involvement in 148 (34.4%), and renal involvement in 192 (44.7%). Purpura manifested after 24 hours of admittance in 64 patients (14.9%) (atypical cases). Multivariate analysis showed that female sex, atypical presentation and early corticosteroid treatment increased the risk of renal involvement (p<0.05). Recurrences, occurring in 22 (5.2%) patients, were correlated with early corticosteroid treatment (p < 0.05). After a mean 17.3 +/- 2.9 months of follow-up, no patient had renal insufficiency. Female sex, atypical presentation and early corticosteroid treatment were considered to increase the risk of developing renal involvement, and relapses occurred more frequently in children treated with corticosteroid. Our study confirmed that HSP is generally a benign disease in children from western Turkey.
