The purpose of this study is to systematically review guidelines, position papers, and reports on living kidney donation by minors. We systematically searched the databases such as Medline, Embase, ISI Web of knowledge, Google scholar as well as the websites of various bioethics committees, transplant organizations and societies. Guidelines were included if they provided recommendations for or against living kidney donation by minors. Data were analyzed using qualitative content analysis. We included 39 documents in this study. Twenty seven of these endorse an absolute prohibition of living kidney donation by minors, because of concerns regarding the decision-making capacity of minors, the impartiality of parental authorization, the best interests of the minor, and the necessity of the donation. Twelve guidelines, however, would exceptionally allow living kidney donation by minors, provided that adequate safeguards are put in place, including an assessment of the minor's autonomy and maturity, authorization by an independent body, assuring that the anticipated psychosocial benefits outweigh the medical and psychosocial risks for the donor and the restriction to situations of last resort. A more adequate medical and psychosocial follow-up of living kidney donors may likely contribute to a more unified approach towards living kidney donation by minors.

Objective: We conducted this study to determine the associations of possible risk factors and prevalence of recurrent otitis media with effusion (OME) in a cohort of children in Upper Egypt. Methods: This was a cross-sectional study undertaken in two tertiary referral centers in Upper Egypt. Associations of possible risk factors with prevalence of recurrent OME were studied. Multi-factor logistic regression analysis was done to recognize the statistically significant risk factors associated with recurrent OME. Results: We collected the data of 2003 pediatric patients, of which 1016 were males (50.7%). A total number of 310 children have OME, including 159 males (51.3%). The prevalence rate of OME in our cohort was 15.5%. Multi-factor logistic regression analysis of the risk factors related to recurrent OME showed it was strongly associated with adenoid hypertrophy (P

Introduction The most common indication for retroperitoneoscopy in children is poorly functioning kidney, related to reflux or obstruction. Few pediatric urologists attempt to conduct a mass resection operation under retroperitoneoscopy, especially in infants with oncological diseases. Aim In this study, we describe our experience in a series of resection operations under retroperitoneoscopy to demonstrate its safety and efficacy in children, especially in the treatment of pediatric urology tumor. Material and methods A retrospective review of 18 consecutive retroperitoneoscopic resection operations from December 2017 to July 2019 was made. Then a comparison study between retroperitoneoscopy and transperitoneal laparoscopy for exclusively oncological patients was conducted. Results Retroperitoneoscopic surgery was successfully performed on 18 patients, 11 having solid tumors, 2 with cysts, and 5 with nonfunctioning or poorly functioning kidneys. The mean age was 69.5 ±46.9 months. The mean operative time was 138.6 ±57.7 min, while the mean size of the mass was 6.4 ±3.8 cm in the largest diameter. Two patients were converted to open surgery because of large diameter of the mass. The 11 solid tumors which were operated on by retroperitoneoscopic surgery were then compared with 13 consecutive oncological patients undergoing transperitoneal laparoscopy. Retroperitoneoscopy has a lower transfusion rate (p < 0.05) and faster recovery (p < 0.01) compared to transperitoneal laparoscopy. Conclusions This study demonstrates that the resection operation of a renal or adrenal specimen under retroperitoneoscopy is feasible and safe in children. It is useful not only to treat patients with benign diseases but also in oncological patients. Retroperitoneoscopy is a recommended surgical approach for children.

Introduction: The process of improving one's skills over time is called a “learning curve”. This term has attracted great attention during the last decades, especially in relation to laparoscopic techniques. Aim: To assess the outcome of paediatric laparoscopic pyeloplasty (LP). Material and methods: Retrospective analysis of the consecutive LPs. The inclusion criteria: (1) children aged < 18 years, (2) transperitoneal approach, and (3) the same operating paediatric urologist (RC). Patients with a history of any procedure on the upper urinary tract were excluded. Any surgical reintervention during follow-up was defined as a failure. The outcomes of LPs performed before 2012 (G1) were compared to those conducted between 2012 and 2016 (G2). Fisher's exact test was used for statistical analysis. Results: Ninety patients met the inclusion criteria, and a total of 95 LPs were performed. The mean operation time was 155 min, and the mean hospitalisation period was 2.4 days. In G1, 19 patients underwent Anderson-Hynes LP, 16 had Fenger non-dismembered LP and two underwent vascular hitch. In G2, 54, 2 and 2 patients underwent these procedures, respectively. The overall success rate was 91.5%. There were six failures in G1 and three in G2 (p = 0.147). Of the Anderson-Hynes LPs, 1/19 in G1 and 3/58 in G2 required reintervention (p = 1). For Fenger LPs, this was 4/16 and 0/2, respectively (p = 1). Only one patient required reoperation after vascular hitch. Conclusions: The surgeons' learning curve reflects their experience with regard to the entire therapeutic process, but not exclusively their manual skills.

This study aimed to report a multi-institutional experience with robot-assisted laparoscopic surgery (RALS) for treatment of urinary tract stones in children. The medical records of 15 patients (12 boys), who underwent RALS for urolithiasis in 4 international centers of pediatric urology over a 5-year period, were retrospectively collected. The median patient age was 8.5 years (range 4–15). Eleven/fifteen patients (73.3%) had concurrent uretero–pelvic junction obstruction (UPJO) and 2/15 patients (13.3%) had neurogenic bladder. Stones were in the renal pelvis in 8/15 (53.3%), in the lower pole in 3/15 (20%), in the bladder in 2/15 (13.3%), and in multiple locations in 2/15 (13.3%). One patient (6.6%) had bilateral multiple kidney stones. The median stone size was 10.8 mm (range 2–30) in upper tract location and 27 mm (range 21–33) into the bladder. Eleven patients with concomitant UPJO underwent simultaneous robot-assisted pyelolithotomy and pyeloplasty in 12 kidney units. Two patients with isolated staghorn stones received robot-assisted pyelolithotomy. Robot-assisted cystolithotomy was performed in two patients with bladder stones. The median operative time was 131.8 min (range 60–240). The stone-free rate was 80% following initial surgery and 100% after secondary treatment. Clavien 2 complications (hematuria, infections) were recorded in 5/15 patients (33.3%). Three/fifteen patients (20%) with residual renal stones were successfully treated using ureterorenoscopy (Clavien 3b). RALS was a feasible, safe and effective treatment option for pediatric urolithiasis in selected cases such as large bladder stones, bilateral kidney stones, staghorn stones or concomitant anomalies such as UPJO requiring simultaneous pyeloplasty.

Introduction Paediatric traumatic brain injury (pTBI) is one of the most frequent neurological presentations encountered in emergency departments worldwide. Every year, more than 200,000 American children suffer pTBIs, many of which lead to long-term damage. Objectives We aim to review the existing evidence on the efficacy of the decompressive craniectomy (DC) in controlling intracranial pressure (ICP) and improving long-term outcomes in children with pTBI. Methods A comprehensive search of the MEDLINE and EMBASE databases led to the screening of 212 studies, 12 of which satisfied inclusion criteria. Data extracted included the number and ages of patients, Glasgow Coma Scale scores at presentation, treatment protocols and short- and long-term outcomes. Results Each of the nine studies including ICP as an outcome reported that it was successfully controlled by DC. The 6–12 month outcome scores of patients undergoing DC were positive, or superior to those of medically treated groups in nine of 11 studies. Mortality was compared in only two studies, and was lower in the DC group in both.Very few studies are currently available investigating short- and long-term outcomes in children with TBI undergoing DC. Conclusion The currently available evidence may support a beneficial role of DC in controlling ICP and improving long-term outcomes.

Introduction Spinal pedicle screw internal fixation has been widely used in adult spine injury fixation. Due to being in a period of continuous growth and development, the spine of children at different ages shows different characteristics from adults in terms of anatomy, physiological function, and biomechanics. Furthermore, because the pedicle of children is small, has large anatomic variation, and has complex adjacent relationships, the surgical risk is extremely high. How to improve the screwing accuracy is the key to the success of children's pedicle internal fixation. Therefore, applying the concept of digitized and individualized screwing will be of great significance to children's pedicle screwing. Aim To investigate the morphologies, development patterns, and aging characteristics of the lumbar vertebral pedicle (LVP) in children aged 6-11 years, and to provide a theoretical basis for screw implantation and related biomechanical studies. Material and methods A total of 60 children aged 6-11 years were selected for the intergroup measurement and statistical analysis of their lumbar diameter, pedicle diameter, screw canal length (SCL), etc. Results Generally, the vertebral foramen diameter (ID), sagittal diameter (SD), pedicle width (PW), and SCL as well as the pedicle height (PH) exhibited an increasing trend with age and increasing vertebral sequence among children aged 6-11 years. Conclusions By observing the LVP in children using 3D digital reconstruction technology, the morphology of the spinal canal and pedicles at different lumbar segments showed obvious development patterns, and the best treatment protocol should be selected according to the LVP characteristics in clinical applications.

Objective Endoscopic third ventriculostomy (ETV) provides a shunt-free treatment for obstructive hydrocephalus children. With rapidly evolving technology, the semi-rigid fiber optic neuroendoscopy shows a potential application in ETV by blunt fenestration. A retrospective analysis of our experience is reviewed. Methods The authors review infants and children who underwent ETV using this technique from June 2004 to June 2016 with radiological and clinical follow-up done by a single surgeon. Patients who underwent ETV with channel scope were excluded. Demographic variables and operative reports were collected. Improvement of preoperative symptoms and avoidance of additional cerebrospinal fluid (CSF) diversion procedures were considered a success. The ETV success score (ETVSS) was used to correlate with clinical outcomes. Results A total of 79 patients were included with a mean age of 8.3 ± 5.5 years, and 40.5% were female. The mean clinical and radiographic follow-up was 38.6 ± 40.9 months. The overall complication rate was 6.3%, while 73.4% were considered successful. The ETV failure cases received conversion to ventriculoperitoneal shunt or redo of ETV with a median time of 2 months. The mean ETV success score was 74.3 ± 11.8 with positive correlation between success rate (P

PURPOSE: Patients with tethered spinal cord have been investigated for short-term effects after tethered spinal cord surgery in the past. However, little is known about the long-term effects in this patient group. In this retrospective, longitudinal, observational study, a patient sample of a previous report of 65 patients was reassessed to observe the long-term effects of intraoperative neurophysiological monitoring-assisted tethered cord surgery.METHODS: With the use of patient charts and a survey, patients were scored on four domains: (1) neurological deficits, (2) urological deficits, (3) pain symptoms, and (4) orthopedic deficits. Measurements were performed at four moments in time: (1) preoperatively, (2) postoperatively, (3) follow-up 1 (4.6 years), and (4) follow-up 2 (11.2 years). Besides this, a subgroup analysis and a quality of life questionnaire were performed.RESULTS: When observing the symptom domains in the long-term, the pain domain appeared to improve most postoperatively after which it remained stable over time. The neurological and urological domains showed a stable, slightly decreasing trend in the long-term follow-up. The orthopedic domain showed a significant increase of the number of patients with scoliosis during the long-term follow-up.CONCLUSIONS: Lasting effects of stability in the neurological, urological, and pain domains were observed. Close monitoring during follow-up might contribute to early recognition of progressive scoliosis, in spite of detethering, in a risk group defined by females who underwent tethered cord surgery at or under the age of 12 years old with either lipomyelomeningocele, split cord malformation, or myelomeningocele. Detethering does not appear to protect these patients against progressive scoliosis.

Medical records of children with vaginal endodermal sinus tumor and rhabdomyosarcoma between 1996 and 2015 were reviewed. A total of 24 patients (median age, 12 months; range, 7–44 months) were included in this study, comprising 17 patients with endodermal sinus tumor and 7 patients with rhabdomyosarcoma. Among the 17 patients with endodermal sinus tumor, 15 were initially treated at our hospital with chemotherapy alone, and 2 were initially treated in other hospitals with conservative surgery and chemotherapy. All 7 patients with botryoid rhabdomyosarcoma received chemotherapy without well-defined protocols. At a median follow-up of 51 months (range, 4–237 months), 3 patients (12.5%; 1 with endodermal sinus tumor and 2 with rhabdomyosarcoma) developed recurrence. At the last follow-up, 22 patients (91.7%) were alive without evidence of disease, 1 patient with botryoid rhabdomyosarcoma died of disease progression, and 1 patient with endodermal sinus tumor died of respiratory and circulatory failure. To allow preservation of sexual and reproductive function, conservative therapeutic strategies should be considered for children with vaginal endodermal sinus tumor and botryoid rhabdomyosarcoma.

Introduction Childhood angular kyphosis is rare, as most children are affected by a mixed kyphotic and scoliotic deformity. Published series involving a mix of kyphosis and kyphoscoliosis, pediatric and adult, congenital and acquired cases are almost exclusively authored by orthopedic surgeons, suggesting that (pediatric) neurosurgeons are not involved.Case series We present five cases that illustrate the spectrum of angular kyphosis, and these were treated by a multidisciplinary team including child neurologist, orthopedic surgeon, and pediatric neurosurgeon as complementary partners.Discussion Angular kyphosis is a cosmetic problem but above all a serious threat to the spinal cord and as such to the child's ambulatory, sphincter, and genito-urinary functions. Spinal cord stretch over the internal kyphosis may cause pain and/or neurological deficit, often accompanied by myelomalacia or even segmental cord atrophy. Spinal cord function may be additionally affected by associated disorders such as syringomyelia or tethered cord, an orthopedic surgeon may be less familiar with. The decision when and how to proceed surgically should be made by a multidisciplinary team, including a pediatric neurosurgeon who actively participates in the operation and helps to safely achieve adequate spinal cord decompression and stabilization.Conclusion Childhood angular kyphosis is a complex, heterogeneous disorder that should be managed by a multidisciplinary team in specialized pediatric spine centers. While every case is truly unique, the spinal cord is always at risk, especially during decompression, stabilization, and eventual correction of deformity. Pediatric neurosurgeons have an important role to play in preoperative work-up, actual operation, and follow-up.

Retinoblastoma is the most common intraocular malignant tumor of childhood. Intra-arterial chemotherapy (IAC) is a recently popularized technique used for the treatment of retinoblastoma, to decrease mortality, increase preservation of the eye, and prevent blindness. Along with the extensive use of IAC, it is important to apply noninvasive examination methods to assess the activity of the tumor and the risk factors for disease dissemination without histopathological confirmation. There are few studies that have assessed the value of magnetic resonance imaging (MRI) in evaluating the efficacy and complications of IAC for retinoblastoma. We retrospectively analyzed the MRI features of 60 patients with unilateral retinoblastoma given the primary treatment of IAC from January 2014 to February 2016 in our hospital. Our study showed that MRI could well assess the decreased activity of the tumor after IAC, presenting with diminished tumor size, increased apparent diffusion coefficient (ADC) values (from 0.94 ± 0.24 × 10-3 mm2/s to 2.24 ± 0.40 × 10-3 mm2/s), and a reduced degree of enhancement of the tumor. Our study also showed that MRI can monitor the risk factors of abnormal enhancement of the postlaminar optic nerve, to avoid unnecessary enucleation. Meanwhile, the results showed that the main late complications after IAC included affected eyeball volume reduction, subretinal hemorrhage, vitreous hemorrhage, vitreous opacity, cataractous len, and choroidal vascular ischemia.

Background Recurrent tonsillitis is a common disease with marked evidence of affecting children quality of life (QOL) such as their progression in school and increased burden to extended families. The aim of this study was to compare the QOL outcomes after conventional dissection tonsillectomy versus azithromycin treatment in controlling recurrent tonsillitis. Methods A double-blind, randomized clinical trial was carried out in 184 children with recurrent tonsillitis randomly divided into two groups: Group A was subjected to conventional dissection tonsillectomy, whereas Group B received single 250 mg (children ≤25 kg) and 500 mg (children ≥25 kg) of oral azithromycin once weekly. Results There were no significant differences between the groups with regard to ear, nose, and throat infections during the 5-year follow-up. Better QOL was observed in both groups when compared with the pretreatment, but similar QOL in both groups QOL after treatment. Conclusion Azithromycin is an effective method as a prophylaxis against recurrent tonsillitis with a great benefit for better QOL outcomes.

Introduction Inguinal hernia is the most common disease in pediatric surgery and is induced by congenital processus vaginalis patency. Almost all inguinal hernias are inguinal indirect hernias, and herniorrhaphy has accounted for about 15% of all pediatric operations. In the past 20 years, with the development of minimally invasive technology, laparoscopic inguinal herniorrhaphy has been emerging in China and in other countries. Aim To introduce a new technique for treating inguinal hernia in children, and evaluate the feasibility and surgical efficacy of a transumbilical single-port laparoscopic water-injection hernia crochet needle in treating pediatric inguinal hernia. Material and methods Clinical data of 136 inguinal hernial children treated using a transumbilical single-port laparoscopic water-injection hernia crochet needle in our hospital from June 2017 to December 2018 were retrospectively analyzed. Results All procedures were successfully accomplished, and no case was converted to a different procedure; the average operation time was 16 min for one side and 35 min for both sides. Patients were followed for an average of 10 months after surgery. One patient had a line-knot reaction at the inguinal puncture point 3 months after surgery and recovered after conservative treatment, and no recurrent case was observed after surgery. Conclusions It is feasible to treat pediatric inguinal hernia through a transumbilical single-port laparoscopic water-injection hernia crochet needle, which is associated with safety, less trauma, rapid recovery, no obvious scar, and satisfactory efficacy. Therefore, it is worthy of being promoted and applied in clinical practice.

Introduction The aim of this study was to present to present our experiences with pediatric mini-percutaneous nephrolithotomies (MPNL) in our center. Material and methods A total of 85 MPNLs performed on 79 pediatric patients being treated for upper urinary tract stones from 2007 to 2017 were analyzed retrospectively in order to determine their safety, efficacy, and relevant outcomes. Results 85 MPNLs performed on 79 patients with a mean age of 6.58 (1-14) years were included in this study. The mean size of the stones was 1.99 (1-6.4) mm. A 17 Fr rigid pediatric nephroscope with a pneumatic intracorporeal lithotripsy was used through a 20 Fr access sheath. The stone-free rate was 87.1% at 1 month postoperatively. Mean operative time was 56.4 (20-120) min. Mean fluoroscopy screening time was 183.2 (40-510) sec. Average hospitalization duration was 4.78 (2-13) days. Auxiliary procedures were performed on 7 (8.2%) patients (5 extracorporeal shock wave lithotripsy, 2 re- percutaneous nephrolithotomy). The complication rate of these cases was 6.3% according to the modified Clavien Classification System. However, no major complications classified as Clavien IV-V were observed in the study group. Conclusions The outcomes of the contemporary analysis confirm that MNPL is a safe and efficient method of intervention resulting in a stone-free state in pediatric cases.

Background The parents of hospitalized children are often dissatisfied with waiting times, fasting, discharge criteria, postoperative pain relief, and postoperative guidance. Parents’ experiences help care providers to provide effective, family-centered care that responds to parents’ needs throughout the day surgery pathway. Objective The objective of our study was to describe parental experiences of the pediatric day surgery pathway and the needs for a digital gaming solution in order to facilitate the digitalization of these pathways. Methods This was a descriptive qualitative study. The participants (N=31) were parents whose children were admitted to the hospital for the day surgical treatments or magnetic resonance imaging. The data were collected through an unstructured, open-ended questionnaire; an inductive content analysis was conducted to analyze the qualitative data. Reporting of the study findings adheres to the Consolidated Criteria for Reporting Qualitative Research (COREQ) checklist. Results Parental experiences of the children’s day surgery pathway included 3 main categories: (1) needs for parental guidance, (2) needs for support, and (3) child involved in his or her own pathway (eg, consideration of an individual child and preparation of child for treatment). The needs for a digital gaming solution were identified as 1 main category—the digital gaming solution for children and families to support care. This main category included 3 upper categories: (1) preparing children and families for the day surgery via the solution, (2) gamification in the solution, and (3) connecting people through the solution. Conclusions Parents need guidance and support for their children’s day surgery care pathways. A digital gaming solution may be a relevant tool to support communication and to provide information on day surgeries. Families are ready for and are open to digital gaming solutions that provide support and guidance and engage children in the day surgery pathways.

Worldwide, viral hepatitis continues to be a cause of considerable morbidity and mortality. Mass immunization with a single dose of live attenuated HAV has been shown to significantly reduce disease burden in the community. This was a phase IV, 5-year follow up study carried out at 4 centers (Kolkata, Delhi, Mumbai and Chennai) across India. The subjects with antibody titer 20 mIU/mL). The seroconversion rates considering seroprotection levels of anti-HAV antibody titer >20 mIU/mL, following vaccination starting from 6 weeks, 6 months, 12 months, 24 months, 36 months, 48 months and 60 months were 95.1%, 97.9%, 98.3%, 96.2%, 97.8%, 92.6% and 97.3%, respectively. The geometric mean concentration (GMC) over the years increased from 64.9 mIU/mL at 6 weeks to 38.1 mIU/mL and 135.2 mIU/mL at 6 months and 12 months, respectively and was maintained at 127.1 mIU/mL at 60 months. In conclusion, the result of this 5-year follow up study showed that the single dose of live attenuated vaccine is well tolerated and provides long-term immunogenicity in healthy Indian children.

Primary spontaneous pneumothorax (PSP) occurs at a frequency of 7.4-18 cases per 100 000 population per year. The PSP typically occurs in young adults and is uncommon in children. The aim of this study was to review our institutional experience with PSP in children.Twenty-two paediatric patients with confirmed PSP, treated from 2004 to 2014 at the Paediatric Surgery Clinic. There were 18 boys and 4 girls. The mean age was 16 years, 6 months ± 1 month (range 14-17). The mean body mass index (BMI) was 20.1 (ranging from 17 to 24).The recurrence rate of PSP was 48%. The mean interval of the recurrence was 5 months ± 1 month (range from 3 weeks to 2 years). Recurrent pneumothorax was evacuated by thoracostomy with success in four patients. The first video-assisted thoracoscopic surgery (VATS) procedure had a failure rate of 50%. After second VATS procedure, we did not observe recurrent PSP in two patients. One patient with recurrent PSP, after two VATS procedures, was treated with success, with an open mini axillary thoracotomy. The mean follow-up period was 4 years 3 months ± 1 month (range 6 months - 10 years). We have not noted any intraoperative complications.Although our study is limited by the small number of patients, we conclude that most patients resolve their spontaneous pneumothorax and air leak with tube thoracostomy alone. For those patients in whom chest tube drainage is not effective, and for those with recurrent PSP, early VATS and bullectomy combined with pleural abrasion is the most efficient intervention.Samoistna odma opłucnowa występuje przeważnie u astenicznych osób, w wieku ok. 18–40 lat. Znacznie częściej chorują mężczyźni niż kobiety. Powstaje zazwyczaj z przyczyn nieznanych. Celem pracy było przedstawienie trudności w leczeniu chirurgicznym samoistnej odmy opłucnowej u dzieci.Dokonano analizy dokumentacji medycznej pacjentów z samoistną odmą opłucnową leczonych w Klinice Chirurgii Dziecięcej Uniwersytetu Medycznego w Białymstoku. W latach 2004–2014 hospitalizowano 22 dzieci z powodu samoistnej odmy opłucnowej – 18 chłopców i 4 dziewczynki, w wieku od 14 do 17 lat (średnio 16,6 miesiąca).W 11 przypadkach (52%) w leczeniu jednostronnej odmy opłucnowej zastosowano jednorazowy drenaż jamy opłucnowej, z dobrym skutkiem. W pozostałych 11 przypadkach wystąpił nawrót odmy, w czasie od 3 tygodni do 2 lat. U pacjentów z odmą nawrotową wykonano drenaż jamy opłucnowej oraz tomografię komputerową (TK) klatki piersiowej. Sześciu pacjentów z tej grupy, na podstawie obrazu TK, w którym stwierdzono obecność pęcherzy rozedmowych, zakwalifikowano do torakoskopii (Poznanie czynników ryzyka powstania nawrotowej samoistnej odmy opłucnowej pozwala na kwalifikowanie chorych do odpowiednich, małoinwazyjnych procedur leczniczych – VATS.

Purpose The purpose of this paper was to study the incidence and clinical significance of fever after intraventricular neuroendoscopic procedures in children. Methods We retrospectively assessed all children subjected to an intraventricular neuroendoscopic procedure between 2004 and 2015. Body temperature 6 days postoperatively, symptoms and signs, and eventual cerebrospinal fluid analysis were evaluated. Fever was defined as temperature above 38 °C. Results Fifty-five children (mean age 4.8 years) had 67 procedures. Forty-three children (47 procedures, 70 %) developed fever, mostly the day of surgery (n = 17; 25 %) or the next day (n = 33; 49 %). All children who were clinically ill (n = 9, including 7 with fever) suffered serious illness, as opposed to none of the children with fever without being clinically ill (n = 36). Fever was unrelated to gender, indication for, and type of procedure and did not influence ETV success rate at 3 months. Children under 1 year less frequently developed fever (p = 0.032). Conclusions Fever frequently develops after intraventricular neuroendoscopic procedures in children and follows a rather predictable course, peaking the day of surgery and/or the next day, and rapidly subsiding thereafter. Fever is not a cardinal symptom except when combined with other symptoms in children who are clinically ill (which most of them are not). Close observation avoiding invasive diagnostic tests may suffice for those who are not clinically ill, while extra attention should be paid to those whose temperature rises after day 2 especially when clinically ill, as they likely suffer serious illness. We recommend to closely observe children after any intraventricular neuroendoscopic procedure for at least 5 days.

SUMMARYIn autumn 2014, enterovirus D68 (EV-D68) cases presenting with severe respiratory or neurological disease were described in countries worldwide. To describe the epidemiology and virological characteristics of EV-D68 in England, we collected clinical information on laboratory-confirmed EV-D68 cases detected in secondary care (hospitals), between September 2014 and January 2015. In primary care (general practitioners), respiratory swabs collected (September 2013–January 2015) from patients presenting with influenza-like illness were tested for EV-D68. In secondary care 55 EV-D68 cases were detected. Among those, 45 cases had clinical information available and 89% (40/45) presented with severe respiratory symptoms. Detection of EV-D68 among patients in primary care increased from 0.4% (4/1074; 95% CI 0.1–1.0) (September 2013–January 2014) to 0.8% (11/1359; 95% CI 0.4–1.5) (September 2014–January 2015). Characterization of EV-D68 strains circulating in England since 2012 and up to winter 2014/2015 indicated that those strains were genetically similar to those detected in 2014 in USA. We recommend reinforcing enterovirus surveillance through screening respiratory samples of suspected cases.

Introduction: Records about the fractures of the distal humerus could be founds in the scriptures written long before Christ (Hippocrates 300 to 400 BC). During the twilight of science development and of any scientific work (the Middle Ages), little has been written about this problem. Between the 1700 and 1800 much was discussed about the controversies between the correct position and immobilization. In the early twentieth century view on the treatment of fractures of the distal humerus begins to change dramatically, from the former passive to active surgical treatment. The sudden turnaround followed thanks to the intensive development of technology, especially new imaging technology. Material and methods: We observed a period of 4 (four) years (1998 to 2002), and only hospital patients of certain age. As database are used the histories of the disease. The patients were followed for one year and at the same time, we analyzed (clinical) early complications after three (3) months and late complications (X ray), after a year. Among the early complications we observed most often lower motility and contraction, and of late we have followed the morphological deformation–cubitus varus and valgus. Results: Using x-ray images, we measured Baumann’s (en face) and lateral condylar angle (profile) after one year in the operated group and the group treated conservatively SPDH type III in children. We calculated the arithmetic mean (x) and a standard deviation (SD) in both groups. Using chi square and t–test, with the probability of 95%, we showed that there is a significant difference between operative and conservative treatment of SPDH type-III in children, according to Gartland. Conclusion : All humerus fracture type-III by Gartland in children should be surgically treated. Surgery should be undertaken in a time frame of 6 hours. Surgery should be done in these cases by the specialized institutions (Clinical Hospital Centre). The success of treatment in such institutions corresponds to the results achieved in the world (93.0%). We must be sure to adopt and implement a scheme of treatment of fractures of the distal humerus in children. Required is faint trail, OPF, lateral (Kaplan) approach, exceptionally for some articular fractures posterior approach by Campbell, fixation with two or more Kirchner’s needles, usually cross-set at an angle of 30°, vacuum drainage with cast immobilization.

Introduction Oesophageal strictures are rare in children but may require endoscopic dilation. Aim To gather information on centres performing endoscopic oesophageal dilation in Poland. Material and methods The data were obtained from questionnaires concerning the relevant data mailed to 22 paediatric endoscopy centres. Completed questionnaires were received from 11 centres. Results In 2010 the 11 Polish paediatric endoscopy centres performed a total of 10,650 endoscopic procedures. This included 347 oesophageal dilations in 106 paediatric patients aged from 1 month to 18 years. The numbers of patients treated at individual centres ranged from 2 to 40. The indications for oesophageal dilation were as follows: postoperative strictures in 68 children, oesophageal burns in 17 children, postinflammatory strictures in 14 children, achalasia in 4 children, and strictures caused by a foreign body in 3 children. Rigid guidewire dilators were used in the majority of procedures (271), rigid dilators without a guidewire in 32 procedures, and balloon dilators in 45 procedures. A total of 203 procedures were conducted under fluoroscopic guidance, and 144 without the use of fluoroscopy. The number of dilating sessions performed in individual children varied from 1 to 6 and more. Conclusions Oesophageal dilation constituted a minor proportion of all paediatric endoscopic procedures. The majority of children requiring dilation were patients up to 3 years of age with postoperative oesophageal strictures. In the majority of the centres rigid guidewire dilators were used, and in one third of the procedures these dilators were introduced without fluoroscopic guidance.

Graft failure is a life-threatening complication after allogeneic haematopoietic stem cell transplantation (HSCT). We report a cohort of 19 consecutive patients (median age: 8·5 years) with acute leukaemias (n = 14) and non-malignant diseases (n = 5) who experienced graft failure after previous HSCT from matched (n = 3) or haploidentical donors (n = 16) between 2003 and 2012. After total nodal irradiation (TNI)-based reconditioning combined with fludarabine, thiotepa and anti-T cell serotherapy, all patients received T cell-depleted peripheral blood stem cell grafts from a second, haploidentical donor. Median time between graft failure and retransplantation was 14 d (range 7-40). Sustained engraftment (median: 10 d, range 9-32) and complete donor chimerism was observed in all evaluable patients. 5 patients additionally received donor lymphocyte infusions. Graft-versus-host disease (GvHD) grade II and III occurred in 1 patient each (22%); no GvHD grade IV was observed. 2 patients had transient chronic GvHD. The regimen was well tolerated with transient interstitial pneumonitis in one patient. Treatment-related mortality after one year was 11%. Event-free survival and overall survival 3 years after retransplantation were 63% and 68%. Thus, a TNI-based reconditioning regimen followed by transplantation of haploidentical stem cells is an option to rescue patients with graft failure within a short time span and with low toxicity.

Background: The pain on propofol injection is considered to be a common and difficult to eliminate problem in children. In this study, we aimed to compare the efficacy of pretreatment with tramadol 1 mg.kg-1and propofol-lidocaine 20 mg mixture for prevention of propofol induced pain in children. Methods: One hundred and twenty ASA I-II patients undergoing orthopedic and otolaryngological surgery were included in this study and were divided into three groups with random table numbers. Group C (n=39) received normal saline placebo and Group T (n=40) received 1 mg.kg-1 tramadol 60 sec before propofol (180 mg 1% propofol with 2 ml normal saline) whereas Group L (n=40) received normal saline placebo before propofol-lidocaine mixture (180 mg 1% propofol with 2 ml %1 lidocaine). One patient in Group C was dropped out from the study because of difficulty in inserting an iv cannula. Thus, one hundred and nineteen patients were analyzed for the study. After given the calculated dose of propofol, a blinded observer assessed the pain with a four-point behavioral scale. Results: There were no significant differences in patient characteristics and intraoperative variables (p>0.05) except intraoperative fentanyl consumption and analgesic requirement one hr after surgery among the groups (p

Single-port laparoscopic cholecystectomy with a 10-mm telescope and inbuilt working channel has been found to be safe, effective, economical, and capable of producing virtually scarless results., Background and Objectives: Multiple single-port or single-incision techniques have been successfully implemented for laparoscopic cholecystectomy in adults and children. These techniques require either a large multichannel port or a larger skin incision to accommodate multiple ports or instruments. Inspired by a first generation single-port instrument, we developed a safe and effective technique for a single-port laparoscopic cholecystectomy with virtually scarless results. Methods: Over a 14-mo period, 20 patients (19 females, 1 male) underwent the hybrid single-port cholecystectomy. A straight 10-mm Storz telescope with inbuilt 6-mm working channel in combination with 2 portless 2.3-mm percutaneous graspers was used. The dissection is carried out with 43-cm bariatric length instruments. The cystic artery and duct are sealed with WECK Hem-o-lok clips or the Harmonic scalpel. Results: Range (mean) age: 7.7 y to 19.5 y (15.5), BMI: 11.6kg/m2 to 42.3kg/m2 (27), operative duration 48 min to 120 min (79), postoperative length of stay: 5 h to 78 h (24). Diagnosis: 13 patients cholecystolithiasis, 7 patients biliary dyskinesia. Conversion to conventional 4-port cholecystectomy was required in 2 patients. No intra- or postoperative complications occurred. Conclusion: The hybrid single-port technique is easy to master. It provides traditional anatomical exposure and allows application of conventional laparoscopic principles.

Introduction Ventricular access devices (VAD) and ventriculosubgaleal shunts (VSGS) are currently both used as temporising devices to affect CSF drainage in neonatal posthaemorrhagic hydrocephalus (PHH), without clear evidence of superiority of either procedure. In this systematic review and meta-analysis, we compared the VSGS and VAD regarding complication rates, ventriculoperitoneal shunt conversion and infection rates, and mortality and long-term disability. Methods The review was registered with the PROSPERO international prospective register of systematic reviews (registration number CRD42015019750) and was conducted in accordance with PRISMA guidelines. Results and conclusions The literature search of five databases identified 338 publications, of which 5 met the inclusion criteria. All were retrospective cohort studies (evidence class 3b and 4). A significantly lower proportion of patients with a VSGS required CSF tapping compared to patients with a VAD (log OR −4.43, 95 % CI −6.14 to −2.72). No other significant differences between the VAD and VSGS were identified in their rates of infection (log OR 0.03, 95 % CI −0.77 to 0.84), obstruction (log OR 1.25, 95 % CI −0.21 to 2.71), ventriculoperitoneal shunt dependence (log OR −0.06, 95 % CI −0.93 to 0.82), subsequent shunt infection (log OR 0.23, 95 % CI −0.61 to 1.06), mortality (log OR 0.37, 95 % CI −0.95 to 1.70) or long-term disability (p = 0.9). In all studies, there was a lack of standardised criteria, variations between surgeons in heterogeneous cohorts of limited sample size and a lack of neurodevelopmental follow-up. This affirms the importance of an ongoing multicentre, prospective pilot study comparing these two temporising procedures to enable a more robust comparison.

Anorectal malformations (ARMs) occur in approximately 1 per 5000 live births. The most commonly used procedure for repair of high ARMs is posterior sagittal anorectoplasty (PSARP). This operation is performed entirely through a perineal approach. The first report of laparoscopically assisted anorectal pull-through (LAARP) for repair of ARMs was presented by Georgeson in 2000. The aim is presenting early experience with laparoscopically assisted anorectal pull-through technique in boys with high anorectal malformations. In the last 5 years 7 boys (9 months to 2 years old) with high ARMs were operated on using the LAARP technique. Laparoscopically the rectal pouch was exposed down to the urethral fistula, which was clipped and divided. Externally, the centre of the muscle complex was identified using an electrical stimulator. In the first 4 patients after a midline incision of 2 cm at the planned anoplasty site, a tunnel to the pelvis was created bluntly and dilated with Hegar probes under laparoscopic control. In the last 3 boys a minimal PSARP was done creating a channel into the pelvis. The separated rectum was pulled down and sutured to the perineum. Laparoscopic mobilization of the rectal pouch and fistula division was possible in all cases. There were no intraoperative complications except one ureteral injury. Patients were discharged home on post-operative day 5 to 7. The early results prove that LAARP, an alternative option to PSARP for treatment of imperforate anus, offers many advantages, including excellent visualization of the pelvic anatomical structures, accurate placement of the bowel into the muscle complex and a minimally invasive abdominal and perineal incision. It allows for shorter hospital stay and faster recovery. However, to compare the functional results against the standard procedure (PSARP), longer follow-up of all patients is necessary.

Objective: Visceral adipose tissue (VAT) is a significant risk factor for obesity-related metabolic diseases. This study investigates (1) the best single CT slice location for predicting total abdominal VAT volume in paediatrics and (2) the relationship between waist circumference (WC), sagittal diameter (SD), gender and VAT volume. Methods: A random sample of 130 paediatric abdomen CT scans, stratified according to age and gender, was collected. Three readers measured VAT area at each intervertebral level between T12 and S1 using ImageJ analysis (National Institute of Health, Bethesda, MD) software by thresholding −190 to −30 HU and manually segmenting VAT. Single-slice VAT measurements were correlated with total VAT volume to identify the most representative slice. WC and SD were measured at L3–L4 and L4–L5 slices, respectively. Regression analysis was used to evaluate WC, SD and gender as VAT volume predictors. Results: Interviewer and intraviewer reliability were excellent (intraclass correlation coefficient = 0.99). Although VAT measured at multiple slices correlated strongly with abdominal VAT, only one slice in females at L2–L3 and two slices in males at L1–L2 and L5–S1 were strongly correlated across all age groups. Linear regression analysis showed that WC was strongly correlated with VAT volume (beta = 0.970, p

Introduction: Esophageal achalasia is a rare entity in children. However, young age is a factor of failure of conservative treatment, emphasizing the role of surgery. In our institution laparoscopic Heller’s cardiomyotomy is the chosen procedure for surgical treatment. Aim: To assess the outcome of surgery for achalasia treatment in children operated on in a single institution. Material and methods: A retrospective analysis of consecutive patient records from the years 1997 to 2014 was performed. There were 11 patients. Their mean age was 13 years, ranging from 6 to 17. Duration of symptoms was 2 to 36 months, mean 16. All 11 patients were operated on with a laparoscopic approach. Pneumatic dilatation was used both pre- and postoperatively but in no case was sufficient on its own. Collected data included patient demographics, preoperative symptoms and their duration, diagnostic findings and therapeutic means. Surgical procedures, complications and long-term follow-up were analyzed. The follow-up lasted from 1 to 10 years and finished when the patient reached 18 years of age. Results: Twelve laparoscopic cardiomyotomies were performed with concomitant fundoplications, 10 Toupet and 2 Dor and one redo procedure. There were no deaths. Two perforations were repaired promptly. The success rate was 82%, though with subsequent dilatations. One failure was due to serious progression of the disease. Conclusions : In our opinion, laparoscopic Heller’s myotomy is the procedure of choice for treating achalasia in children. Endoscopic balloon dilatation may be used as a complementary treatment, especially as a primary redo procedure.

Background and Objectives: Laparoscopic splenectomy for massive splenomegaly is still a controversial procedure as compared with open splenectomy. We aimed to compare the feasibility of laparoscopic splenectomy versus open splenectomy for massive splenomegaly from different surgical aspects in children. Methods: The data of children aged

Purpose The use of a minimally invasive approach for adrenalectomy is poorly defined in pediatric patients, although laparoscopic adrenalectomy is considered a standard procedure in adults. The aim of our study was to describe the safety and feasibility of minimally invasive adrenalectomy in children on the basis of surgical skills and results. Materials and methods This was a retrospective study of 4 pediatric laparoscopic adrenalectomies performed at our center between 2009 and 2012. All patients underwent transperitoneal lateral laparoscopic adrenalectomies (2 right and 2 left adrenalectomies). Results Four laparoscopic adrenalectomies were performed. Indications for surgery were neuroblastoma in 2 patients, secernent adrenocortical tumor in 1 patient, and adrenocortical nodular hyperplasia in 1 patient. Patients had a mean age of 87 months (range, 17-156 months) at diagnosis, and the average lesion size was 3.23 cm (range, 0.7-6.4 cm). All laparoscopic adrenalectomies were successful, no conversions to open surgery were required, and no postoperative complications or deaths occurred. The average operating time was 105 minutes (range, 80-130 minutes), blood loss during surgery was minimal, and the mean postoperative hospital stay was 3.75 days (range, 3-5 days). None of the patients showed signs of recurring disease at 15-month follow-up. Conclusions Laparoscopic adrenalectomy is a safe, feasible, and reproducible technique offering numerous advantages, including shortening of operating times and postoperative hospital stays, as well as reduction of blood loss and complications. It also provides good visibility and easy access to other organs.

Objective: To assess the interrater agreement of the diagnosis and the classification of a first paroxysmal event in childhood. Methods: The descriptions of 100 first paroxysmal events were submitted to two panels each consisting of three experienced paediatric neurologists. Each observer independently made a diagnosis based on clinical judgment and thereafter a diagnosis based on predefined descriptive criteria. Then, the observers discussed all patients within their panel. The agreement between the six individual observers was assessed before discussion within each panel and after that, between the two panels. Results: Using their clinical judgement, the individual observers reached only fair to moderate agreement on the diagnosis of a first seizure (mean (SE) kappa 0.41 (0.03)). With use of defined descriptive criteria the mean (SE) kappa was 0.45 (0.03). The kappa for agreement between both panels after intra-panel discussion increased to 0.60 (0.06). The mean (SE) kappa for the seizure classification by individual observers was 0.46 (0.02) for clinical judgment and 0.57 (0.03) with use of criteria. After discussion within each panel the kappa between the panels was 0.69 (0.06). In 24 out of 51 children considered to have had a seizure, agreement was reached between the panels on a syndrome diagnosis. However, the epileptic syndromes were in most cases only broadly defined. Conclusions: The interrater agreement on the diagnosis of a first seizure in childhood is just moderate. This phenomenon hampers the interpretation of studies on first seizures in which the diagnosis is only made by one observer. The use of a panel increased the interrater agreement considerably. This approach is recommended at least for research purposes. Classification into clinically relevant syndromes is possible only in a very small minority of children with a single seizure.

Introduction: Despite the increase in use of laparoscopic appendectomy (LA) in recent years, until now no nationwide survey on this issue has been performed in Poland. Aim: To determine current surgical practice patterns among Polish pediatric surgeons in the treatment of appendi- citis in children. Material and methods: The nationwide survey was conducted in the form of an internet questionnaire asking for information concerning treatment of children suspected of having acute appendicitis in the years 2007-2011. Twen- ty-seven major pediatric surgical departments in Poland were invited to participate in the study. Results: The overall survey response rate was 70.37%. Laparoscopic appendectomy was offered in all departments except one. Laparoscopy was used in 33% of cases and was the standard procedure in 4 departments. In 1 center 100% of appendectomies were performed laparoscopically. The 3-port technique was used in all departments. Five centers offered transumbilical laparoscopic extracorporeal appendectomy and 2 centers single-port appendectomy. In LA the mesoappendix was mostly divided using bipolar or monopolar coagulation and the appendix was ligated using endoloops or was clipped. The mean hospitalization time was 3.31 days after laparoscopy and 5.47 days after open appendectomy. Conclusions: Despite an apparent consensus on some aspects of pediatric appendicitis among Polish pediatric sur- geons, significant inconsistency exists in the operative approach. The low rate of LA suggests that LA still remains far from being a standard. Personal experience and preference have a major influence on the choice of operative approach. It is recommended that national guidelines be set up, which could standardize the care for children and training of pediatric surgery residents.

Background: Pulse wave velocity (PWV), a measure ofarterial stiffness strongly predictive of cardiovascular riskin adults, is usually measured by sequential ECG-referenced carotid and femoral tonometry. A simplifiedtechnique, more suitable for use in children, employssimultaneous volumetric recording from a sensor appliedover the carotid artery and a cuff applied over thefemoral artery or arm and thigh pressure cuffs appliedover the brachial and femoral arteries. The purpose ofthis study was to compare PWV computed over thecarotid-femoral path (PWVcf) with that over thebrachial-femoral path (PWVbf) using a volumetric system(Vicorder) and to compare values of PWVcf obtained bythe volumetric and a tonometric method (SphygmoCor)in children.Method: Vicorder PWVcf and PWVbf were comparedin 156 children (3–18 years, 110 with chronickidney disease), and PWVcf by Vicorder wascompared to PWVcf by SphygmoCor in a subset of122 patients.Results: PWVcf by Vicorder was moderately correlatedwith PWVcf by SphygmoCor (R¼0.50, P

Introduction: Prolapse of the rectum is the herniation of the rectum through the anus, which may be categorised as mucosal or complete. Aim: To evaluate the clinical manifestation, treatment, and surgical complications of children with rectal prolapse over a 6-year period. Material and methods: This study was carried out on children aged < 14 years who were admitted or referred for rectal prolapse that failed to respond after medical treatment in Imam Khomeini and Abouzar Children’s Hospital. Duration of the study was 6 years starting in March 2002. These cases were referred after failure of medical and conservative treatment. Age, sex, clinical manifestation, and type of procedure were recorded. Analysis was done using SPSS version 11.0 (SPSS Inc, Chicago, IL, USA). The χ2 test was used for comparison. Results: Seventy-one cases were included in this study. Of these cases, 50 (70.4%) were male and 21 (29.6%) were female (p < 0.0001). Mean age of cases was 4.97 ±3.42 years (range: 2 days to 13 years). Of the male cases, 38% were in the age range of 3–6 years. In female cases, 57.1% were in the range of 1.5–3 years. Of all 71 cases, injection sclerotherapy was done for 50 (70.43%) for the first time. Twenty-one cases had history of injection sclerotherapy and 16 (22.53%) were treated by perineal surgery, and 5 (7.04%) had abdominal surgery. One case experienced recurrent rectal prolapse (1.40%) following injection sclerotherapy. Conclusions: In girls, more than half of the cases were in the age range 1.5–3 years. Among male cases, 38% were in the age range of 1.5–3 years. The results of treatment of rectal prolapse in our hospitals was similar to that seen in developed countries.

We investigated the functional and radiological outcomes of conservatively treated simple traumatic elbow dislocations and subsequent incidence of cubitus valgus development in children. Eleven patients (one female, ten male; mean age 9.8 years, range seven to 12 years) who presented to our hospital with simple elbow dislocations and were conservatively treated between July 2008 and September 2010 were included in the study. All were posterolateral closed dislocations. None of the patients had accompanying elbow fractures. All patients had pre- and postoperative radiographic examinations. The carrying angle of the involved elbow was measured and compared to the contralateral non-injured elbow during follow-up. The incidence and severity of cubitus valgus development was assessed. The functional and clinical outcomes were evaluated using the Mayo Elbow Performance Scale. The mean monitoring period was 24.3 months (range 19-30 months). All patients had satisfactory good and excellent results (85-100 points; mean 96.8 points) according to the Mayo Elbow Performance Scale. The final average elbow flexion was 137A degrees (range, 130-145A degrees) and average extension was 8.6A degrees (range 0-20A degrees) with full supination and pronation in traumatic elbow. Four patients (36.4 %) had an average increase (cubitus valgus) of 14.5A degrees (10-20A degrees) in carrying angle compared to the other elbow. While isolated traumatic dislocation of the elbow is uncommon among children, it can be successfully treated by urgent closed reduction, proper fixation of the elbow and appropriate timely rehabilitation. However, it should be considered that some patients may develop cubitus valgus deformity in a later period. Therefore, each patient with a simple traumatic elbow dislocation should be followed, and the parents should be informed of the potential for any deformity development.

Objective To assess the efficacy of cultured epidermal autografts (CEA) for closure of burn wounds in pediatric burn patients with full-thickness burns of more than 90% total body surface area. Summary Background Data Paucity of donor sites in massive burns makes the use of expanded skin of paramount importance. CEA techniques have been used in burned patients with differing and controversial results. The true impact and the efficacy of such techniques in massive burns remain uncertain. Methods Patients with full-thickness burns of more than 90% body surface area treated between May 1988 and May 1998 were studied. Patients grafted with CEA were compared with patients grafted with conventional meshed autografts. Rates of death and complications, length of hospital stay (LOS), hospital cost, acute readmissions for reconstruction, and quality of scars were studied as outcome measures. Results Patients treated with CEA had a better quality of burn scars but incurred a longer LOS and higher hospital costs. Both groups had comparable readmissions for open wounds, but patients treated with CEA required more reconstructive procedures during the first 2 years after the injury. The incidence of sepsis and pneumonia in both groups was comparable. Conclusions Conventional meshed autografts are superior to CEA for containing hospital cost, diminishing LOS, and decreasing the number of readmissions for reconstruction of contractures. However, the use of CEA provides better scar quality such that perhaps future research should focus on bioengineered dermal templates to promote take and diminish long-term fragility.

Purpose Femoral derotation osteotomy (FDO) is commonly used to correct internal rotation gait (IRG) in spastic diplegia. The purpose of this study was to investigate whether the extent of intraoperative derotation is reflected in changes in static (clinical ROM and anteversion angle measured on torsional MRI) and dynamic parameters (transverse plane kinematics in three-dimensional gait analysis) after FDO in children with spastic diplegia.Methods In a prospective study, 30 children with spastic diplegia and IRG were treated with FDO as part of a multilevel surgery and were examined pre- and postoperatively clinically, by three-dimensional gait analysis and by torsional MRI according to a standardised protocol.Results A correlation (r = 0.317, p = 0.015) between the extent of intraoperative derotation and mean hip rotation in stance as well as the anteversion angle measured on torsional MRI (r = 0.454, p Conclusions Significant improvements were found in IRG after FDO, confirming the results of previous studies. There was no correlation between the anteversion measured on MRI and the mean hip rotation in stance in 3D gait analysis before or after FDO. Thus, the data suggest that if the intraoperative extent of derotation is determined only by the anteversion angle, the result will not be better after FDO. It might only help to avoid retroversion and indicate the maximum amount of femoral derotation. In this study the extent of the intraoperative derotation was orientated at the preoperative midpoint of rotation. Based on the small, but significant correlation between the clinical midpoint and the mean hip rotation in stance in the gait analysis, determination of the intraoperative extent of derotation according to the mean hip rotation in stance seems to give the best results.

Introduction: Percutaneous internal ring suturing (PIRS) is a method of laparoscopic herniorrhaphy, i.e. percutaneous closure of the internal inguinal ring under the control of a telescope placed in the umbilicus. Aim: To evaluate the usefulness of the PIRS technique. Material and methods: Fifty-five children (39 girls and 16 boys) underwent surgery using this method in our institu- tion between 2008 and 2010. Results: In 10 cases the presence of an open inguinal canal on the opposite side was also noted during surgery, and umbilical hernia was recognized in 2 patients. In 5 cases it was necessary to convert to the open surgery because of the inability to continue the laparoscopic procedure. In 1 case, male pseudohermaphroditism was diagnosed during surgery. Recurrent inguinal hernia required a conventional method of surgery in 1 child. Other children did not ex- hibit the characteristics of hernia recurrence. The inguinal canals were followed up with postoperative ultrasound examination in 29 children. In 23 children, the ultrasound examination showed no dilatation of the inguinal canal. In the other 6 children dilatation of the inguinal canal or the presence of fluid within the inguinal canal was observed during ultrasound. In 6 children symptoms such as swelling and soreness around the inguinal canal developed within 3 to 6 months after surgery. Conclusions: Inguinal hernia surgery using the PIRS procedure is an alternative, effective, minimally invasive method of surgery. Visualization of the peritoneal cavity allows for detection of other abnormalities, as well as for performing other procedures during the same session (such as closing the contralateral inguinal canal or umbilical hernia surgery).

Three hundred and twenty-two patients (192 male and 130 female) with cystic lesions of the jaw were successfully diagnosed and treated. One hundred and fifty-five (48%) were radicular cysts, 80 (25%) were dentigerous cysts, 23 (7%) were odontogenic keratocyst (=keratocystic odontogenic tumor), 19 (6%) were eruption cysts, 16 (5%) were traumatic bone cysts, and 29 (9%) were non-odontogenic cysts. There were 95 in the pediatric age group (1 month to 16 years) and 227 in the adult age group (17 years and older). Male to female ratio was 1 in the pediatric age group and 1.7 in the adult age group. The treatment modalities were: marsupialization, enucleation, enucleation with bone grafting, or resection. The distribution and characteristics of jaw cysts in children are different from those in adults. In children there is a relatively high rate of developmental cysts, whereas in adults the inflammatory cysts are more common. Following enucleation of a cystic jaw lesion, the entire surgical specimen and not only a biopsy specimen, should be examined histopathologically to prevent any possibility of an intramural squamous cell carcinoma that may be overlooked. The differences in prevalence of each type of jaw cyst during a lifetime may point toward a multifactorial polygenic pattern rather than a monogenic pattern.

Introduction Gastroesophageal reflux (GERD) is common in neurologically impaired (NI) children. Fundoplication and gastrostomy have previously been indicated in NI children with GERD who have not responded to medical treatment. The most common reason for fundoplication failure is intrathoracic migration of the wrap. Objective The aim of the study is to measure the effect of wrap fixation on the final outcome of laparoscopic Nissen fundoplication in NI children. Patients and methods A retrospective file review was conducted for all NI children who underwent laparoscopic Nissen fundoplication in 2 tertiary pediatric surgery centers in the United Arab Emirates from February 15, 2006 to February 15, 2013. Redo fundoplication patients were excluded from the study. Patients were divided into 2 groups: group 1 in which the fundoplication wrap was fixed to the right crus only, and group 2 in which the wrap was fixed to the right and left crus simultaneously. Results The study population included 68 patients; there were 47 male and 21 female children. Mean age at time of surgery was 8.2 years. Recurrent GERD at 1 year postoperatively was 26% versus 7% in group 1 and group 2, respectively, by upper contrast study. Redo surgery was required in 21% versus 3% in group 1 and group 2, respectively. Conclusions Bilateral fixation of the wrap to diaphragmatic crura significantly reduced recurrent GERD, in laparoscopic Nissen fundoplication for neurologically impaired children, with no increased risk of morbidities. Future prospective studies should be conducted with larger patient populations and longer follow-up periods.

Purpose The aim of the study is to characterize changes in circulating proteasome (c-proteasome) activity following mild traumatic brain injury in children. Methods Fifty children managed at the Department of Pediatric Surgery because of concussion—mild head injury was randomly included into the study. The children were aged 11 months to 17 years (median = 10.07 + −1.91 years). Plasma proteasome activity was assessed using Suc-Leu-Leu-Val-Tyr-AMC peptide substrate, 2–6 h, 12–16 h, and 2 days after injury. Twenty healthy children admitted for planned inguinal hernia repair served as controls. Results Statistically significant elevation of plasma c-proteasome activity was noted in children with mild head injury 2–6 h, 12–16 h, and 2 days after the injury. Conclusions Authors observed a statistically significant upward trend in the c-proteasome activity between 2–6 and 12–16 h after the mild head injury, consistent with the onset of the symptoms of cerebral concussion and a downward trend in the c-proteasome activity in the plasma of children with mild head injury between 12–16 h and on the second day after the injury, consistent with the resolving of the symptoms of cerebral concussion. Further studies are needed to demonstrate that the proteasome activity could be a prognostic factor, which can help in further diagnostic and therapeutic decisions in patients with head injury.

Purpose The aim of the study was to compare the radiological indicators of effectiveness for hydrocephalus treatment in children operated on under the third year of age with the use of shunt insertion (SI) and endoscopic third ventriculostomy (ETV). The effectiveness was considered in terms of postoperative neurodevelopment in correlation to pre- and postoperative radiological findings. Methods The examined group consisted of 46 children operated on for hydrocephalus in the Division of Pediatric Neurosurgery in Katowice, Poland. There were 21 children treated with SI and 25 with ETV. The radiographic assessment was carried out on the basis of MRI and CT examinations with the use of a linear estimate known as frontal and occipital horn ratio (FOR). The FOR values were calculated for the entire group and in correlation to the treatment method and to the children neurodevelopment evaluated with The Denver Developmental Screening Test. Results No differences were recognized between initial FOR value in terms of the postoperative children neurodevelopment. In the successful ETV-treated subgroup, the mean change in FOR was 0.05 and in the SI-treated subgroup, the mean change in FOR 0.13. The patients with BFOR >0.1, developed normally more often than those in whom BFOR was lower than 0.1. Conclusions The initial FOR value probably does not affect the postoperative developmental outcome. Long-term change in ventricles size after surgery can correlate with psychomotor development of hydrocephalic children. Presumably, there are no differences between two treatment options according to initial FOR values and to changes in FOR values.

The aim of the study was to assess the correlation of the results of the treatment of infratentorial ependymomas with the degree of resection and histopathological diagnosis. The study was conducted on a group of 19 patients, 13 boys and 6 girls aged 3 months to 16 years, with infratentorial ependymoma treated at the Department of Paediatric Neurosurgery of the Medical University of Silesia in Katowice from January 2000 until December 2008. The most significant factor having an impact on overall survival and progression-free survival was totality of tumour resection. There has been no statistically significant influence of the histopathological type of ependymoma on the result of treatment. The tendency to report better results of treatment of non-anaplastic ependymoma seems to derive from a statistically higher frequency of total removal of tumours of this type.

The paper presents an unsystematized review of technologies, techniques and options for surgical treatment of congenital spinal deformities in children over the past 40 years. The main trends in the surgery of spinal deformities are highlighted: evolution of methods of visual diagnostic, treatment planning, and surgeon action control, introduction of adapted functional status scales and questionnaires for quality of life, hybridization of surgical techniques, evolution of spinal implants and instruments, and progress of anesthetic management. At the same time, new clinical and scientific problems are also discussed in the paper: questions of unifying terminology, planning the volume of treatment, the difficulty of comparing treatment methods and technologies, education, and integration.

Introduction Although covid-19 infection manifest with mild symptoms in children, it might be serious or even fatal forms of this disease. Case report In this paper, we report three cases of severe forms of pulmonary covid-19 infection in children with several studies have shown that the mortality rate is higher in adults, mainly the elderly and the immune compromised, on the other hand a severe form in children with hospitalization in intensive care is often lethal. Conclusion Mortality in the pediatric population with covid-19 is linked to both the severity of the pulmonary involvement and the heavy impact of intensive care., Highlights • Covid-19 is a severe infection with severe complications that might lead to death. • Children are considered are the risk group. • In this paper, we will represent the case report of 3 children with severe outcomes (2 deaths and 1 patient survived).

Minimally invasive surgery (MIS) has represented the main innovation in the field of pediatric surgery and urology over the last 30 years. Pediatric MIS is a wide field, ranging from the standard laparoscopic surgery using 3-mm ports to robotics mainly adopted for pediatric urology indications. The aim of this paper was to summarize the current status of robotic surgery in pediatric urology and to evaluate possible future technical developments for this technique. In pediatric urology, many procedures are challenged by the narrow working space available in smaller children, the difficulty to perform complex and long suture lines to repair complex urinary malformations, and the challenge to remove renal or adrenal tumors. The main characteristic of robotic surgery is that the robotic instruments inserted into the abdominal cavity are remotely controlled by the surgeon, who is sitting at a console next to the patient or even far away, avoiding human tremor during complex suturing. Due to the magnification of the operative field view and the six degrees of freedom of the robotic instruments compared to conventional laparoscopic instruments, providing enhanced 3D vision and improved surgeon ergonomics, robot-assisted surgery appears to be beneficial over conventional MIS, especially in complex reconstructive procedures. Currently, there are two robotic systems available on the market and certified for robotic surgery in children: the DaVinci (Intuitive Surgical, since 2001) and Senhance (Transenterix, since 2020). However, almost the totality of papers published in the international literature are focused on robotic procedures using the DaVinci platform. Analyzing the current literature, there is no evidence about the indications where robotics are preferable to conventional MIS approaches. Currently, the main indications of robotic surgery in pediatric urology are: pyeloplasty for ureteropelvic junction obstruction (UPJO), ureteral reimplantation according to Lich Gregoire technique, Mitrofanoff procedure, nephrectomy or partial nephrectomy for oncological indications, removal of renal cysts, bladder neck reconstruction or removal of urinary tract stones. The future developments in this field are certainly represented by intraoperative use of indocyanine green (ICG) fluorescence imaging that permits to have a better vision of vascular anatomy or clearly identify nodes in case of tumors, and by development of 5G technology. The main limitation of robotic surgery today remains the excessive cost of the machine itself and the limited lifespan of robotic instruments. We believe that robotic surgery will surely represent the new field of development in pediatric surgery, but its widespread application will depend on the introduction of new robotic platforms in the market, that will certainly low the costs, and also to the development of smaller size instruments more suitable for pediatric use.

Background When severe limb trauma occurs in a child, all efforts are made to preserve the limb as far as possible. In rare cases, however, secondary amputation may be necessary to improve functional outcome and participation. Case report In this paper, we report on a young adolescent male with a severe loss of function following foot trauma, who underwent secondary trans-tibial amputation 17 months post injury. This paper describes how a structured multidisciplinary approach around the child and his family led to a successful outcome. Clinical rehabilitation impact It is hoped that this case report may help other health professionals with decision-making in cases of secondary amputations, and to implement appropriate follow-up for such patients.

Context: Supraglottic Airway Devices (SADs) are applied in airway management of pediatric emergency conditions. Objective: This review study aimed to examine the literature regarding pediatric supraglottic airway devices, to introduce the optimal devices in terms of Oropharyngeal Leak Pressure (OLP), risk of insertion failure on the first attempt and risk for blood staining of the device. Data Sources: An electronic search was conducted on MEDLINE, EMBASE, CINAHL and PubMed databases. We also searched the Cochrane database (CENTRAL) and Web of Science up to July 1, 2017. Study Selection: Of 112 potential studies, the full texts of 53 articles were available, in which 15 were duplicated and omitted, accordingly. Papers which did not directly discuss SADs were also excluded. In total, 30 papers were identified related to the children supraglottic devices. Data Extraction: The current review was conducted and reported in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement. Results: The LMA ProSeal may be the best supraglottic airway device for children due to its high oropharyngeal leakage pressure and low risk of insertion failure. It seems that i-gel is a very functional tool as well. Conclusions: Further research is recommended to investigate the most appropriate supraglottic airway in diverse clinical situations and various conditions among children.
