Traumatic optic neuropathy (TON) is characterized by impaired visual function due to acute damage to the optic nerve injury related to the trauma. The predictive incidence of TON in children and adolescence is 0.7-2.5% after blunt or penetrating head injuries. Orbital trauma is often accompanied by head injury and is the most common cause of unilateral vision loss. Here, we present a case of 11-year-old child who had the complaint of vision loss in the right eye and developed TON after a motor vehicle accident. The intubated patient was admitted to the pediatric intensive care unit after trauma and was operated due to epidural hemorrhage. Visual loss was detected during follow-up and orbital computed tomography revealed multiple fractures in the orbital walls and magnetic resonance imaging showed effusion of the optic nerve sheath and contrast enhancement of the optic nerve. Clinical and imaging findings suggested TON and as there was no indication for surgery, pulse steroid treatment was given for 5 days. With this treatment, the patient's vision loss and clinical findings improved significantly.In conclusion, TON should be considered in patients with a head injury and post-traumatic vision loss. High-dose steroids should be considered in suitable patients.

Background Multisystem inflammatory syndrome in children (MIS-C) is characterized by persistent fever, abdominal pain, vomiting, diarrhea, rash, conjunctivitis, headaches, and mucocutaneous manifestations and it can cause circulatory dysfunction, resulting in hypotension, shock, and end-organ injury in the heart and other organs and possibly death. In this study, we aimed to analyze the clinical spectrum, treatment options and outcomes of children with MIS-C who were admitted to our pediatric intensive care (PICU). Materials and Methods Clinical and laboratory findings and treatment of the patients admitted to the PICU with MIS-C between April 2020 and January 2021 were recorded, and their outcomes were evaluated. Results Nineteen patients with a median age of 12.5 years (interquartile range (IQR): 5.8–14.0 years) were admitted. Eleven (57.8%) were males. The most frequent clinical and laboratory features were fever (100%), abdominal pain (94.7%), rash (63.1%), headache (68.4%), diarrhea (47.3%), seizure (10.5%), cardiac dysfunction (52.6%), acute kidney injury (26.3%), lymphopenia (84.2%), and thrombocytopenia (36.8%). However, 8 patients needed mechanical respiratory support, 11 patients needed inotropes, 2 patients needed plasma exchange, and 1 patient needed continuous renal replacement therapy. All patients received corticosteroids, 17 patients (89.2%) received intravenous immunoglobulin, 2 patients received anakinra, 10 patients received acetylsalicylic acid, and 6 patients received enoxaparin. Median PICU length of stay was 3 days (IQR: 2–5) and only one patient died. Conclusion In conclusion, MIS-C may present with a variety of clinical manifestations, and it can lead to life-threatening critical illness. Most children need intensive care and the response to immunomodulation is usually favorable.

The aim of this study is to determine the effects of local anesthetics administered intraperitoneally in laparoscopic appendectomy.Patients who underwent laparoscopic appendectomy due to acute appendicitis were enrolled in the study. The children were divided into two groups. Intraperitoneal bupivacaine injection to appendectomy site and subdiaphragmatic area was performed after resection of appendix and aspirastion of intraperitoneal reactive fluid in Group 1 while Group 2 did not receive this therapy. The children were questioned by a nurse at postoperative 1st, 6th, 12th, and 24th h. Pain scores (PS) (abdominal), abdominal wall incisional pain (IP), shoulder pain (SP), and first need for analgesics were recorded.One hundred and twenty children were enrolled to the study. There was no significant difference in PS values and IP values between the two groups (p0.05). SP values at 12th and 24th h were significantly lower in Group 1 (p0.05). There was a statistically significant reduce in analgesic need in Group 1 (p=0.007).Intraperitoneal bupivacaine instillation to surgery site and subdiaphragmatic area seems to reduce the SP post-opera-tive and also reduce post-operative analgesic need. More meaningful results can be obtained with an increase in the number of patients.

Objective: Megameatus intact prepuce is described as subset of megalourethra or distal hypospadias by several authors. Despite suggested different operative techniques, some authors prefer not to operate this variant of penile anomaly. We aimed to evaluate 31 patients operated due to megameatus intact prepuce and associated anomalies . Material and methods: Thirtyone patients operated between 2008-2018 for MIP were evaluated retrospectively. All data were collected from hospital records. Patient age, application reasons, raphe anomalies, associated genitourinary and extragenitourinary pathologies, operative techniques, and postoperative complications were analyzed. Results: Mean age was 50 months (8-128 months). Ten of the patients had raphe anomalies. Genital raphe hyperpigmentation was seen in 1 patient, raphe deviation and bifurcated raphe was seen in6 and 3 patients respectively. Genitourinary anomalies were detected in 7 patients, bilateral undescended testes in 1 patient, penile chordee in 2 patients, ureteropelvic junction obstruction in 2 patients, penoscrotal web in 1 patient, nocturnal enuresis in one patient. Tubularized incised plate urethroplasty (TIPU) (n=5), tubularized urethral plate urethroplasty (TUPU)(n=16) and meatoplasty (n=10) were the operative techniques. Conclusion: . Co-occuring raphe anomalies should arise awareness of MIP among the clinicians who are engaged with the children’s medical conditions and also the possible anomalies especially in the societies which circumcision is not traditionally required. Further studies with large number series needed for better understanding of this pathology.

Background and Aims Urinary system complications after hematopoietic stem cell transplantation (HSCT) cause severe morbidity and mortality. The aim of the study is to investigate the incidence and risk factors of urinary system complications in patients who had HSCT during their childhood. Method Patients who had HSCT between January 2010-2019 with a minimum follow-up period of 6 months were included in the study. Data regarding urinary system complications were collected from the medical records of the patients. pRIFLE and KDIGO classification systems were used for the definition of acute kidney injury (AKI). Results 167 patients (108 males and 59 females) with allogeneic (n=165) and autologous (n=2) HSCT were investigated for renal complications. In cohort, HSCT was performed in 41 patients (%24.6) secondary to malignant diseases and in 126 patients secondary to non-malignant diseases. Hemorrhagic cystitis (HC) developed in 28 patients (16.8%) after HSCT. The mean age of the patients with and without HC was 14.6±5.6 years and 10.5±6 years, respectively (p=0.044). Among patients with HC, 17 had concomitant viral infection. Presence of viral infection, gender, disease group, history conditioning regime, total body irradiation, acute graft-versus-host disease and veno-occlusive disease (VOD) did not have any effect on the development of HC in logistic regression analysis. In cohort, 126 patients (75.4%) developed AKI according to KDIGO classification (stage 1; 55 patients, stage 2; 36 patients, stage 3; 35 patients). The mean period of development of AKI after HSCT was 34±22 days. The risk of AKI (according to KDIGO) was higher in patients who had HSCT secondary to malignant diseases and/or who developed viral infections after HSCT (p=0.034 and p=0.013, respectively). Among patients, 71 patients (%42.5) developed AKI according to pRIFLE classification. The risk of AKI (according to pRIFLE) was higher in patients who had HSCT secondary to malignant diseases, who developed viral infections and/or who developed VOD during follow-up (p=0.043, p=0.001 and p=0.006, respectively). One patient developed thrombotic microangiopathy after HSCT. None of the patients had nephrotic syndrome during follow-up period. Conclusion Patients who had HSCT secondary to malignant disease, viral infections and/or VOD had higher risk of AKI and should be closely monitored.

Objective Critically ill children often require transport to tertiary centers where higher levels of care can be provided. In this study, we aimed to evaluate the reasons for transport, complications that occurred during transport, and the clinical outcomes of the patients transferred to our tertiary pediatric intensive care unit (PICU). Methods This retrospective study was conducted in a tertiary pediatric hospital with 250 beds and 20 tertiary PICU beds. Results During the study period, 108 patients were transferred to our PICU. The mean age was 75.0 ± 70.5 months (range, 1-211 months), and 59 were female. Most patients (82.4%) were transported by land; 17.6% were transported by air ambulance. Fourteen patients were referred for liver transplantation, and 7 patients were referred because of a need for extracorporeal membrane oxygenation support and heart transplantation or left ventricular assist device placement. Two patients were transported by air while on extracorporeal membrane oxygenation. Complications occurred in 25% of patients. Conclusion Vital signs were assesed, and certain critical interventions such as intravenous fluids and respiratory support were provided more frequently during air transport, possibly due to the fact that physicians were always present during air transport. Quality improvement of transport teams and multicenter and nationwide studies on PICU transport are needed.

Background and Objective The aim of this multicenter retrospective study was to determine the clinical characteristics, treatment approaches and the course of pediatric acute respiratory distress syndrome (PARDS) which developed associated with the influenza virus in the 2019–20 season. Methods Patients included 1 month to 18 years who were diagnosed with PARDS associated with the influenza virus in the 2019–20 season. Results Sixty-seven patients were included in the study. The mean age of the patients was 64.16 ± 6.53 months, with 60% of the group Conclusion Both Influenza A and Influenza B cause severe PARDS with similar characteristics and at high rates. Influenza-related PARDS cause 33% mortality and 15.5% morbidity among the study group. Healthy children, especially those aged younger than 5 years, are also at risk.

Background and Aims The aim of the study is to investigate the incidence and risk factors of hypertension (HT) and chronic kidney disease (CKD) in patients who had hematopoietic stem cell transplantation (HSCT) during their childhood. Method Patients who had HSCT between January 2010-2019 with a minimum follow-up period of 6 months were included in the study. Data regarding renal complications were collected from the medical records of the patients. Guidelines of European Society of Hypertension (ESH) and American Academy of Pediatrics (APA) were used for the evaluation of hypertension. 24-hr ambulatory blood pressure monitoring (ABPM) was performed in children older than 5 years of age (68 patients). Ambulatory hypertension is diagnosed when systolic and/or diastolic blood pressure (BP) load is higher than 25%. Ambulatory prehypertension is diagnosed when mean systolic and/or diastolic BP is less than 95th percentile with systolic and/or diastolic BP load higher than 25%. Results A total of 72 patients (41 males and 31 females) were included in the study. The mean age of the patients at last visit was 10.8±4 years. ABPM revealed ambulatory HT in 6 patients (8.8%) and ambulatory prehypertension in 12 patients (17.6%). Office BP revealed HT in 3 patients (4.2%) and increased BP in four patients (5.6%) according to APA guideline (2017). In cohort, 12 patients with normal office BP (according to APA guideline) had ambulatory prehypertension or hypertension with ABPM. Office BP revealed HT in 1 patient (1.4%) and high-normal BP in 3 patients (4.2%) according to ESH guideline. In cohort, 15 patients with normal office BP (according to ESH guideline) had ambulatory prehypertension or hypertension with ABPM (Table 1). After a mean follow-up period of 4.4±2.5 years, CKD developed in 8 patients (11.1%). Patients with chronic graft-versus-host disease, with HLA-mismatched HSCT and/or transplantation of peripheric or cord blood hematopoietic stem cells had increased risk of CKD (p=0.041, p=0.033 and p=0.002, respectively). Conclusion Patients with HSCT should be regularly followed for the development of HT and ABPM should be used on regular basis. Patients with risk factors should be closely monitored for the development of CKD.

Objective This study aims to retrospectively evaluate the long-term efficacy, tolerability, and safety of therapeutic plasma exchange (TPE) in children with various neuroimmunological disorders. Methods This analysis was a single-center, retrospective cohort study of pediatric patients with neuroimmunological events undergoing TPE procedures in a tertiary referral center. Results There were 23 patients, 14 boys (60.9%), aged at diagnosis onset 8 months to 16.8 years. The main indications of TPE were Guillain-Barre syndrome (GBS, n = 8), autoimmune encephalitis (n = 5), febrile infection-related epilepsy syndrome (FIRES, n = 4), and acute disseminated encephalomyelitis (ADEM, n = 3). There was no life-threatening complication due to the TPE procedures. Eight (34.8%) of 23 patients experienced 13 (7%) complications in 186 TPE procedures, mostly electrolyte disturbances (n = 5). None of patients discontinued TPE due to complications. Two (8.7%) of 23 patients had marked improvement, 6 (26.1%) had moderate and 11 (47.8%) had mild improvement after TPE. The last follow-up visit revealed neurological sequelae in 12 (52.2%) patients. Therapeutic plasma exchange was found to be more effective on GBS, autoimmune encephalitis and myasthenia gravis, less effective on ADEM and FIRES. There was no correlation between improvement with TPE and clinical parameters, including age, sex, diagnosis, disease duration before TPE, presence of intubation, and length of stay in the intensive care unit and hospital. Conclusion Therapeutic plasma exchange was found to be effective and well-tolerated in children with various types of neuroimmunological disorder, with at least mild improvement in approximately 80% of the patients and no life-threatening complications.

Objectives Laparoscopic gastrostomy is a widely used procedure in children with failure to thrive, feeding disorders, or neurologic impairment. Various methods of laparoscopic gastrostomy and fixing stomach to abdominal wall have been described. Trocar site primary gastrostomy under laparoscopic control is a simple and easy technique that does not require special instruments and a kit. The aim of this study was to present 10 years of experience in laparoscopic gastrostomy. Methods The charts of 128 children who underwent laparoscopic gastrostomy between 2006 and 2016 were retrospectively reviewed. The data, including demographics, operative procedures, and complications, were recorded. All children underwent preoperative contrast imaging and 24-hour Ph monitorization. In all patients, the trocar site primary gastrostomy was done. A gastrostomy tube or a button was inserted into the stomach in the center of a purse-string suture loop, and the stomach was fixed to the anterior rectus sheath extracorporeally. Results There were 49 girls (38.3%) and 79 boys (61.7%). The mean age was 50 months at surgery (1 day-18 years), and the average body weight was 13 kg (2300 gr-65 kg). Both laparoscopic Nissen fundoplication and gastrostomy were done in 116 (90.6%) patients, and 12 (9.4%) patients had only laparoscopic gastrostomy. Infection at the site of gastrostomy, which was treated by antibiotics, was the most common complication, observed in 14 (11%) patients. Peritoneal leakage within 30 days was seen in 9 (7%) patients. Severe dislodgement of gastrostomy resulting in operative intervention occurred in 5 (3.9%) patients. Granuloma developed in 4 (3.1%) patients and was treated with silver nitrate. Conclusion The trocar site primary laparoscopic gastrostomy is a safe and easy technique with complication rates comparable to other gastrostomy methods.
