Abstract Objective In this study, we investigated the efficacy of percutaneous poking reduction and Kirschner wire fixation in older children with irreducible supracondylar flexion-type fractures of the humerus. Methods This retrospective investigation included 27 children, comprising 15 males and 12 females, aged between 10 years and 3 months to 14 years and 11 months, all diagnosed with a flexion-type supracondylar fracture of the humerus within one week of trauma. All patients underwent surgery under general anesthesia. Following unsuccessful manual reduction, percutaneous poking reduction with Kirschner wires was performed under C-arm fluoroscopy to achieve fracture reduction. Following successful reduction, three 2.0 mm Kirschner wires were inserted in a cross pattern to secure the fracture ends. Postoperatively, the elbow joint was immobilized in a functional position with a plaster cast for four weeks. Results Follow-up in the outpatient department ranged from 9 to 36 months. Clinical functional assessment using Flynn’s criteria rated 24 cases as excellent, 2 as good, and 1 as fair, yielding an overall efficacy of 96.3%. No cases of fracture re-displacement, fracture fragment necrosis, or other complications such as nonunion, iatrogenic nerve injury, myositis ossificans, or long-term elbow joint dysfunction were observed during the postoperative follow-up. Conclusion The percutaneous poking reduction and Kirschner wire fixation technique is a simple and reliable procedure for treating irreducible flexion-type supracondylar fractures of the humerus in older children, with minimal trauma. This technique offers substantial stability for the fracture and results in excellent long-term recovery of joint function.

Individuals with autism spectrum disorder (ASD) often exhibit motor deficits that increase their risk of falls. There is a lack of understanding regarding gait biomechanics demonstrated by older children with ASD. The purpose of the study was to determine differences in gait patterns between older children with ASD and typically developing children. Eleven children with ASD and 11 age- and gender-matched typically developing children were recruited for the study. Participants walked on a force-instrumented treadmill at a constant speed (1.1 ​m/s ​- ​1.2 ​m/s) for five minutes (min). Participants performed maximal voluntary contractions to assess their knee muscular strength. Differences between individuals with ASD and matched control participants were examined through paired t-tests with a significance level of p ​≤ ​0.05. Individuals with ASD demonstrated a smaller knee extensor torque compared to controls (p ​= ​0.002). Participants with ASD exhibited a shorter stride length (p ​= ​0.04), a greater cadence (p ​= ​0.03), and a higher variation in stride width (p ​= ​0.04) compared to control participants. The individuals with ASD experienced a greater braking ground reaction force (p ​= ​0.03) during loading response. The results indicate older children with ASD develop a unique gait pattern signified by a reduced stride length, increased cadence, and an increase of variation in stride width. This unique gait pattern may represent a movement strategy used by the individuals with ASD to compensate for the weakness associated with their knee extensor muscles. Individuals with ASD who demonstrate these unique gait deviations may face reduced postural stability and an increased risk of fall-related injuries.

Despite a significant reduction in the burden of malaria in children under five years-old, the efficient implementation of seasonal malaria chemoprevention (SMC) at large scale remains a major concern in areas with long malaria transmission. Low coverage rate in the unattainable areas during the rainy season, a shift in the risk of malaria to older children and the rebound in malaria incidence after stopping drug administration are mainly reported in these areas. These gaps represent a major challenge in the efficient implementation of SMC measures. An open randomized study was conducted to assess the effect of a fifth additional round to current regime of SMC in older children living in Dangassa, a rural malaria endemic area. Poisson regression Model was used to estimate the reduction in malaria incidence in the intervention group compared to the control group including age groups (5-9 and 10-14 years) and the use of long-lasting insecticidal nets (LLINs; Yes or No) with a threshold at 5%. Overall, a downward trend in participation rate was observed from August (94.3%) to November (87.2%). In November (round 4), the risk of malaria incidence was similar in both groups (IRR = 0.66, 95%CI [0.35-1.22]). In December (round 5), a decrease of 51% in malaria incidence was observed in intervention group compared to control group adjusted for age groups and the use of LLINs (IRR = 0.49, 95%CI [0.26-0.94]), of which 17% of reduction is attributable to the 5th round in the intervention group. An additional fifth round of SMC resulted in a significant reduction of malaria incidence in the intervention group. The number of SMC rounds could be adapted to the local condition of malaria transmission.

Background: Distal radius fractures in older children pose a challenge in terms of treatment due to the lack of specific guidelines and controversies surrounding the optimal approach. The purpose of this study was to examine the effectiveness of antegrade intrafocal pinning (AIP) in treating volar displaced distal radius fractures in older children. Methods: This was a retrospective study of 12 consecutive patients with volar displaced distal radius fractures treated with an antegrade intra-focal pinning technique between 2017 and 2021. The study evaluated functional outcomes using the quick DASH score, modified Mayo wrist score, and grip strength. MRI of the wrist was done in all patients two years after the initial surgery. Results: The mean follow-up period of the study was 26 months (range 20–32 months). All patients achieved radiological union. The mean range of wrist flexion was 74°, extension 52°, radial deviation 22°, ulnar deviation 27°, and grip strength was 96% of the opposite side. The visual analogue scale score was 0 (range 0–1), and the quick DASH score was 4.3. The mean Mayo wrist score was 84 (range 80–85). None of the patients experienced growth arrest, growth plate deformity, physeal bar, or bridges on MRI. Conclusions: The AIP technique is safe and effective for treating volar displaced distal radius fractures in older children. The technique provides good radiological union and functional outcomes without physeal or growth plate injuries. Level of evidence: Level IV, Therapeutic [ABSTRACT FROM AUTHOR]

Abstract Background The epidemic rebounds observed in 2010 and 2013 in Dielmo, a Senegalese village, during a decade (2008–2019) of universal coverage using a long-lasting insecticidal net (LLIN) strategy could have contributed to the resurgence of malaria. Thus, this study was undertaken to understand the implications of net ownership and use on malaria rebound events. Methods A longitudinal study was carried out in Dielmo with 11 years of LLIN implementation from July 2008 to June 2019 with successive net renewals in 2011, 2014, 2016 and 2019. Quarterly cross-sectional surveys were performed to assess LLIN ownership and use by different age groups in the population. In addition, malaria incidence and transmission were assessed during the study period. Results Ownership of LLINs decreased significantly from 88% in the 1st year of net implementation to 70% during the first malaria upsurge and 72% during the second upsurge while net use decreased significantly from 66% during the 1st year to 58% during the first malaria upsurge and 53% during the second upsurge. Among young adults aged 15–29 years, net use decreased significantly from the 2nd year (51%) of net use to reach 43% during the first malaria upsurge and only 32% use during the second malaria upsurge. During the second malaria upsurge, net use was significantly lower among older children aged 10–14 years old than during the 1st year of net use (p

Abstract Objective The purpose of this study was to compare the therapeutic effects of Kirschner wire fixation and external fixation in the treatment of proximal humeral fractures in older children and adolescents. Methods A retrospective analysis was performed on the clinical data of older children and adolescents who underwent surgery at our institution for proximal humeral fractures between April 2014 and May 2022. One group (n = 28) underwent fracture reduction and Kirschner wire fixation, and the other group (n = 23) underwent external fixation. During the follow-up, the differences in shoulder joint function between the two groups were compared by analysing Quick Disabilities of the Arm, Shoulder, and Hand (Quick DASH) and Constant-Murley scores. Postoperative complications were also recorded. Results The operation time of the Kirschner wire group was shorter than that of the external fixation group (69.07 ± 11.34 min vs. 77.39 ± 15.74 min, P = 0.33). The time to remove the fixator in the external fixation group was shorter than that in the Kirschner wire group (6.74 ± 1.57 vs. 7.61 ± 1.22, P = 0.032). The Quick DASH score and Constant-Murley score of the patients in the external fixation group were significantly better than those in the Kirschner wire group at 3 months after surgery (5.63 ± 4.33 vs. 8.93 ± 6.40, P = 0.040; 93.78 ± 2.43 vs. 91.75 ± 2.15, P = 0.003). There was no significant difference in the Quick DASH score or Constant-Murley score between the patients in the external fixator group and those in the Kirschner wire group at 9 months after the operation (2.77 ± 3.14 vs. 3.17 ± 3.68, P = 0.683; 97.39 ± 1.80 vs. 96.57 ± 2.15, P = 0.152). The most common complication of the two groups was pin tract infection. The incidence rate of infection was higher in the external fixation group than that in the Kirschner wire group (9 vs. 4, P = 0.043). Conclusion Both Kirschner wire fixation and external fixation of N-H III and IV proximal humeral fractures in older children and adolescents produce good outcomes. External fixation is a preferred surgical treatment option for paediatric proximal humerus fractures because early mobilization of the affected limb can be realized.

ObjectiveMalformations of the lower limbs caused by hypophosphatemic rickets in older children are mostly complex, occurring on multiple planes without a single apex and showing arcuate bending of the diaphysis combined with torsion deformity, and are difficult to correct. This study retrospectively investigated the effect of and indicators for multi-segment osteotomy with interlocking intramedullary nail fixation in the treatment of bony deformity caused by hypophosphatemic rickets.MethodsThe clinical data of 21 hypophosphatemic rickets patients seen between August 2007 and March 2022 were collected. The age range of the patients at the first surgery was 11 years and 1 month old to 15 years and 3 months old, with an average age of 12 years and 8 months. There were 6 males and 15 females. All patients had abnormal alignment of their lower limbs, with 32 limbs having varus deformity and 10 limbs having valgus deformity.ResultsA total of 67 surgeries were performed across the 21 patients, including 24 cases of femoral osteotomy with antegrade intramedullary nail fixation, 6 cases of femoral osteotomy with retrograde intramedullary nail fixation, and 20 cases of tibial osteotomy with interlocking intramedullary nail fixation. A total of 34 limbs eventually underwent interlocking intramedullary nail fixation, 9 with genu valgum and 25 with genu varus. All 21 patients were followed up for a period of 14∼96 months, with an average of 42.6 months. The ends of the osteotomies achieved bony union in 4–9 months (average 6.8 months), after which normal weight-bearing walking could be resumed. No infection, vascular or neurological complications, or nonunion occurred. During postoperative follow-up, the alignment the lower limbs passed through zone 1 in 13 limbs, zone 2 in 12 limbs, and zone 3 in 5 limbs. The overall rate of an excellent effect was 83.3%.ConclusionFor lower limb deformity caused by hypophosphatemic rickets in older children, multi-segment osteotomy and strong fixation with interlocking intramedullary nails can achieve good correction outcomes.

Introduction: Lipoblastoma is a rare benign mesenchymal tumor of embryonic fat that occurs almost exclusively in infants and children. It accounts for less than 1% of childhood neoplasms and is found in slightly higher frequency in males compared to females. Lipoblastomas most commonly occur in the extremities and show variable rates of growth. Surgical excision is the treatment of choice and has an excellent prognosis although recurrences are possible. Case presentation: We report two cases of lower extremity lipoblastoma at 7 and 8 years of age. Both patients presented with a slow-growing painless mass over the thigh with no limitation in the range of motion of the joints of the affected limb. Plain films showed well-demarcated soft tissue masses. Cytological examination was suggestive of lipoblastoma which was later confirmed by histopathology examination. Complete surgical excision with meticulous dissection and preservation of vital neurovascular structures was done in both cases. No recurrence has been observed after 5 years of follow-up. Conclusion: Lipoblastomas should be considered as a possible diagnosis in older children presenting with a solid slow-growing soft tissue mass.

This article explores the motivations and decision-making processes of parents who adopt older children from the UK care system. It draws on interview data from parents from 14 adoptive families to consider what influenced their decision to adopt an older child. Data were analysed thematically, and the analysis was theoretically informed by the concept of adoption as a 'marketplace'. The study shows how prospective adoptive parents can be influenced in their decision-making by the information they have been given or perceive about the state of the adoption marketplace and indicates that making choices and decisions around the characteristics of future children is often an uncomfortable aspect of the process. The participants cited moral reasoning and notions of fate as key factors influencing their decisions. The article concludes by making recommendations for practice. Plain language summary: In this research, parents from 14 families who adopted older children (children aged four and over when they moved into their adoptive home), were asked about why they made the decision to adopt an older child. This is important, as older children are often more difficult to find adoptive homes for than younger children. We found that the messages given in adoption preparation courses and by social workers influenced parents' thoughts around the child or children that they went on to adopt. Parents in the study highlighted that making choices and citing preferences around the characteristics of their future child or children was an uncomfortable part of the adoption process. Several parents saw adopting an older child as a way to provide a permanent home for a child that might not otherwise have this chance. Many spoke of the strong sense of connection they felt to their new child, even before they had met them. Ways to improve practice are noted. [ABSTRACT FROM AUTHOR]

Abstract Background The objective of this study is to investigate the preparation of a navigation template via a computer-aided design (CAD) and 3D printing (3DP) in order to improve the effectiveness of Tönnis triple osteotomy in older children with developmental dysplasia of the hip (DDH). Method Thirty-eight older children who received Tönnis triple osteotomy were included in this study. Among them, 20 were categorized as the 3DP navigation template group (3DP group), and the remaining 18 were categorized as the conventional surgery group (CS group). Data, including preoperative and postoperative pelvic sharp angle (SA), lateral center-edge angle (LCEA), acetabular roof angle (ARA), acetabular head index (AHI), crossover sign (COS), ischial spine sign (ISS), operation time (OT), intraoperative blood loss (IBL), and number of radiation exposures (NORE) were recorded for both groups. In addition, the therapeutic effect was evaluated at the last follow-up, according to the McKay criteria and Severin’s criteria. Results In the 3DP and CS groups, the mean OT was 126.6 ± 17.6 min and 156.0 ± 18.6 min, respectively; the mean IBL was 115.0 ± 16.9 ml and 135.7 ± 26.5 ml, respectively; the NORE were 3.3 ± 0.8 times and 8.6 ± 1.3 times, respectively. There were significant differences in the OT, IBL, and NORE between the two groups (P = 0.03, 0.05,

AIM: To investigate the effect of perioperative synoptophore scintillation training on postoperative restoration of binocular visual function in patients with constant exotropia.METHODS: We retrospectively reviewed 68(136 eyes)patients with constant exotropia, who successfully underwent surgical ophthalmological treatment from January 2017 to March 2021. Patients were divided into group A(n=35 cases, 70 eyes)and group B(n=33 cases, 66 eyes)according to whether or not they received perioperative synoptophore scintillation training. Group A included 19 males(38 eyes)and 16 females(32 eyes)(mean age: 29.34±12.72 years). Group B included 13 males(26 eyes)and 20 females(40 eyes)(mean age: 30.12±8.75 years). One month postoperatively, the patients were examined with a synoptophore, and the restoration of simultaneous vision, fusion function, and stereoscopic function were compared between the two groups.RESULTS: There were no significant differences in age, sex, and preoperative far and near deviations between the two groups(P>0.05). Postoperatively, the restoration rates of simultaneous vision, fusion function, and stereoacuity were 54%, 54%, and 43% in group A, respectively. And 27%, 27%, and 15% in group B, respectively. Statistically, there were respectively significant differences between the two groups(χ2=5.117, 5.117, 6.280; all P12 years)with constant exotropia without binocular vision function and enhance the therapeutic effect of surgery.

Despite a significant reduction in the burden of malaria in children under five years-old, the efficient implementation of seasonal malaria chemoprevention (SMC) at large scale remains a major concern in areas with long malaria transmission. Low coverage rate in the unattainable areas during the rainy season, a shift in the risk of malaria to older children and the rebound in malaria incidence after stopping drug administration are mainly reported in these areas. These gaps represent a major challenge in the efficient implementation of SMC measures. An open randomized study was conducted to assess the effect of a fifth additional round to current regime of SMC in older children living in Dangassa, a rural malaria endemic area. Poisson regression Model was used to estimate the reduction in malaria incidence in the intervention group compared to the control group including age groups (5–9 and 10–14 years) and the use of long-lasting insecticidal nets (LLINs; Yes or No) with a threshold at 5%. Overall, a downward trend in participation rate was observed from August (94.3%) to November (87.2%). In November (round 4), the risk of malaria incidence was similar in both groups (IRR = 0.66, 95%CI [0.35–1.22]). In December (round 5), a decrease of 51% in malaria incidence was observed in intervention group compared to control group adjusted for age groups and the use of LLINs (IRR = 0.49, 95%CI [0.26–0.94]), of which 17% of reduction is attributable to the 5th round in the intervention group. An additional fifth round of SMC resulted in a significant reduction of malaria incidence in the intervention group. The number of SMC rounds could be adapted to the local condition of malaria transmission.

We detected human metapneumovirus (HMPV) in 54 (5%) of 1055 children aged 5 to 13 years with acute respiratory illness (ARI) identified by outpatient and emergency department surveillance between November and May 2003-2009. Its clinical features were similar to those of HMPV-negative ARI, except a diagnosis of pneumonia was more likely (13% vs 4%, respectively; P = .005) and a diagnosis of pharyngitis (7% vs 24%, respectively; P = .005) was less likely in patients with HMPV- positive ARI than those with HMPV-negative ARI.

Complete transposition of the great arteries is a common life-threatening complex cyanotic congenital heart disease in infants, resulting in the operation usually performed about one week after birth. However, little is known about the surgical strategy and experience of transposition of the great arteries with an intact ventricular septum in older patients. Herein, we present an abandoned 7-year-old boy with severe cyanosis with clubbed fingers and toes and then diagnosed with transposition of the great arteries with an intact ventricular septum, atrial septal defect, patent ductus arteriosus, and pulmonary hypertension. The patient underwent a two-staged procedure: an aortopulmonary shunt and pulmonary artery banding were performed at the first stage, followed by the Switch operation, defect repair, and patent ductus arteriosus ligation, all of which were successfully performed. The patient was discharged on the 15th day after the operation, and the arterial oxygen saturation returned to normal level (99%). The illustrative report highlights the essence of raising awareness and developing accurate treatment strategy of transposition of the great arteries, especially in remote rural areas of eastern countries, where the level of health care and services is relatively underdeveloped.

Aim:Vesicoureteral reflux (VUR) is an important risk factor for urinary tract infection (UTI). We aimed to investigate the relationships between VUR and ultrasound with late dimercaptosuccinic acid (DMSA) scan findings in children aged older than two years who had their first febrile UTI (FUTI).Materials and Methods:Data from those patients with their first FUTI were retrospectively analyzed. A late DMSA scan was performed at least 6 months after an acute FUTI. The late DMSA scans were graded as mild (focal defect in uptake), moderate (uptake of renal radionuclide from 20 to 40%), and severe (shrunken kidney with uptake less than 20%). Micturating cystourethrography was performed at 3 to 6 weeks after the FUTI.Results:The records of 220 patients (61 mild VUR, 60 severe VUR, 99 without VUR) were reviewed. An abnormal US was more common in those patients with VUR than those without VUR (p=0.009). Abnormal US had a sensitivity of 79.34% for VUR and 81.67% for severe VUR. The negative predictive value of renal US for severe VUR was 91.13%. The frequency of renal scarring was higher in those patients with VUR than for those without VUR (102/44, p=0.001). A logistic regression analysis showed significant associations between abnormal US and VUR or severe VUR (p=0.019 and p=0.011, respectively). Renal scarring had a sensitivity of 84.3% for VUR, and 91.67% for severe VUR.Conclusion:Late DMSA scan findings can predict the presence and grade of VUR in older children who have their first FUTI. Normal renal US can predict the absence of severe VUR.

Abstract Objective To evaluate the efficacy of ultra-early rehabilitation on elbow function after Slongo’s external fixation for supracondylar humeral fractures in older children and adolescents. Methods We retrospectively analyzed clinical data from 49 older children (> 8 years) and adolescents with supracondylar humerus fracture who were treated with Slongo’s external fixation in our hospital from January 2016 to August 2020. Twenty-three patients received ultra-early postoperative rehabilitation (rehabilitation group) and 26 patients were not subjected to postoperative rehabilitation (control group). Time to ROM required for functional activity of daily living(ROM-ADL) in both groups was recorded postoperatively. Patients were followed up at 3 and 6 months after surgery to compare the elbow range of motion (ROM) and carrying angle (CA). Postoperative complications were assessed in both groups. Flynn scores and modified Mayo Elbow Performance Scores were also performed. Results The elbow function at 6 months after surgery was significantly better than that at 3 months in the control group (P = 0.32). Time to ROM-ADL in the rehabilitation group was significantly shorter than that of the control group (P = 0.028). The elbow function, Flynn scores, and modified Mayo scores in the rehabilitation group at 3 and 6 months after surgery were significantly better than that of the control group (P(ROM, 3 months and 6 months) = 0.012 vs 0.039; P(Flynn scores, ROM, 3 months and 6 months) = 0.028 vs 0.005; P(Flynn scores, CA, 3 months and 6 months) = 0.032 vs 0.026; P(Modified Mayo scores, 3 months and 6 months) = 0.039 vs 0.024; respectively). There were no iatrogenic injuries, secondary fracture displacements, myositis ossificans, elbow deformities, or other complications in either group. One case of nail tract infection occurred in the rehabilitation group and was cured. Conclusion Slongo’s external fixation is a safe and effective surgical treatment for supracondylar humeral fractures in children over 8 years old and adolescents. Ultra-early rehabilitation treatment for postoperative children can significantly speed up the recovery after surgery.

Abstract Objective The standard surgical treatment for supracondylar humeral fractures in children is closed reduction and percutaneous pinning. Given the need for greater fixation strength and higher risk of joint stiffness for children older than 8 years, external fixation is often performed for treating supracondylar humeral fractures in older children. The aim of this study was to compare the efficacy of lateral entry pins and Slongo’s external fixation for treating supracondylar humeral fractures in older children. Methods Children older than 8 years who underwent surgery for supracondylar humeral fractures at our hospital for surgery from January 2016 to December 2020 are to be retrospectively assessed. One group (n = 36) underwent internal fixation and percutaneous pinning with three lateral Kirschner wires, and the other group (n = 32) underwent Slongo’s external fixator surgery. The demographic data, operation duration, number of fluoroscopies, and fracture healing time were compared between both groups. The elbow joint function was evaluated 6 months after the surgery on the basis of fracture healing time, lifting angle, elbow joint range of motion (ROM), and Flynn score. The incidence of postoperative complications was also recorded. Results There was no significant difference between the two patient groups in terms of the demographic parameters. Compared to external fixation surgery, Kirschner wire surgery required shorter duration and fewer fluoroscopies (P < 0.05). Nevertheless, the fracture healing time was significantly less (P < 0.05), and the elbow ROM and Flynn scores were higher in the external fixator group compared to the Kirschner wire fixation group (P < 0.05). There was one case of secondary fracture displacement in the Kirschner wire group and one of pin tract infection in the external fixator group. No other iatrogenic injuries or complications were observed. Conclusion Maybe Slongo’s external fixator is a suitable alternative treatment option for supracondylar humeral fractures in children older than 8 years since it can achieve better fixation strength and early restoration of elbow joint movement with a lower risk of joint stiffness.

In addition, the therapeutic effect was evaluated at the last follow-up, according to the McKay criteria and Severin's criteria.Results: In the 3DP and CS groups, the mean OT was 126.6 ± 17.6 min and 156.0 ± 18.6 min, respectively; the mean IBL was 115.0 ± 16.9 ml and 135.7 ± 26.5 ml, respectively; the NORE were 3.3 ± 0.8 times and 8.6 ± 1.3 times, respectively. There were significant differences in the OT, IBL, and NORE between the two groups (P = 0.03, 0.05, < 0.001, respectively). At the last follow-up, the 3DP and CS groups displayed SA of 41.8 ± 2.3° and 42.6 ± 3.1°, respectively; LCEA of 35.6 ± 4.2° and 37.1 ± 2.8°, respectively; ARA of 6.9 ± 1.8° and 9.8 ± 2.6°, respectively; and AHI of 86.6 ± 4.1% and 84.3 ± 2.8%, respectively; COS(+) of 5 hips and 4 hips, respectively; ISS(+) of 6 hips and 7 hips. We observed no statistical differences in the SA, LCEA, ARA, AHI, COS and ISS between the two groups (P = 0.918, 0.846, 0.643, 0.891, 0.841, 0.564, respectively). According to the McKay criteria, the 3DP group had 10 excellent, 6 good, and 4 general hips, whereas, the CS group had 12 excellent, 4 good, and 2 general hip. There was no statistical difference between the two groups (P = 0.698). In 3DP group the postoperative Severin's grading included 13 hips in grade I, 4 in grade II, 3 in grade III. Alternately, in the CS group, the postoperative Severin's grading included 11 hips in grade I, 5 in grade II, 2 in grade III. The Severin 's criteria also showed no statistical difference between the two groups (P = 0.945).Conclusions: Base on our analysis, our CAD-3DP-fabricated navigation template assisted Tönnis triple osteotomy in older DDH children, it reduced operation time and number of radiation exposures. However, no significant differences in radiological assessment and functional outcomes were observed when an experienced surgeon performs the surgery. Therefore, Surgeons who have less experience in triple osteotomy profit more from the application of this technology. [ABSTRACT FROM AUTHOR]

Abstract Background There are disputes about which reduction technique should be adopted in treatment of distal radius-ulna fractures in older children who failed to achieve manual reduction. This study compared clinical effects between prying reduction with mosquito forceps (PRMF) and limited open reduction (LOR) of treating irreducible distal radius-ulna fractures in older children. Methods One hundred ten children with irreducible distal radius-ulna fractures were selected from January 2015 to December 2017 in Xi’an Hong Hui hospital. Retrospective analysis was performed. According to different reduction techniques, these children were divided into PRMF group (59 cases) and LOR group (51 cases). All children were treated with percutaneous Kirschner wire fixation and external fixation with plaster. Operation indexes, complications and wrist joint functions were compared between the two groups. Results Operation time of PRMF group was shorter than that of LOR group (P

Background: Cancer in the United States is a leading cause of mortality. Educating adolescents about cancer risks can improve awareness and introduce healthy lifestyle habits. Public health efforts have made significant progress in easing the burden of cancer through the promotion of early screening and healthy lifestyle advocacy. However, there are limited interventions that educate the adolescent population about cancer prevention. Previous studies have demonstrated the effectiveness of serious games (SGs) to teach adolescents about healthy lifestyle choices, but few research efforts have examined the utility of using SGs to educate youth specifically on cancer prevention. Objective: This study aimed to investigate middle school students' preferences for the use of SGs for cancer prevention education. The study also characterized the students' perceptions of desired game design features for a cancer prevention SG. Methods: Focus groups were held to allow adolescents to review a game playbook and discuss gaming behaviors and preferences for an SG for cancer education. The game playbook was developed based on "Cancer, Clear & Simple," a curriculum intended to educate individuals about cancer, prevention, self-care, screening, and detection. In the game, the player learns that they have cancer and is given the opportunity to go back in time to reduce their cancer risk. A focus group discussion guide was developed and consisted of questions about aspects of the playbook and the participants' gaming experience. The participants were eligible if they were 12 to 14 years old, could speak and understand English, and had parents who could read English or Spanish. Each focus group consisted of 5 to 10 persons. The focus groups were audio recorded and professionally transcribed; they were then analyzed content-wise and thematically by 2 study team members. Intercoder reliability (kappa coefficient) among the coders was reported as 0.97. The prevalent codes were identified and categorized into themes and subthemes. Results: A total of 18 focus groups were held with 139 participants from a Wisconsin middle school. Most participants had at least "some" gaming experience. Three major themes were identified, which were educational video games, game content, and purpose of game. The participants preferred customizable characters and realistic story lines that allowed players to make choices that affect the characters' outcomes. Middle school students also preferred SGs over other educational methods such as lectures, books, videos, and websites. The participants desired SGs to be available across multiple platforms and suggested the use of SGs for cancer education in their school. Conclusions: Older children and adolescents consider SGs to be an entertaining tool to learn about cancer prevention and risk factors. Their design preferences should be considered to create a cancer education SG that is acceptable and engaging for youth. [ABSTRACT FROM AUTHOR]

Background Longer lives increase the possibility of caring duties, which means that older adults looking after their ageing parents—as well as their own partners—is becoming an increasingly common scenario in developed countries. Objective To explore the caregiving demands of very old caregiving dyads and the experience of maintaining the identity of a child at such an advanced age. Design Qualitative study. Subjects 15 participants (four males), all aged 70 or over and caring for their mothers, aged between 95 and 105 years old. Methods Semi-structured interviews analysed thematically. Results Caregivers are willing to care for their mothers 'until death tears them apart', despite the double strains they face, that is more self-limitations and added care receiver need. On a positive side, they feel 'happy, thankful and proud' for still having their mothers alive. They also describe that maintaining the identity of a child at such an advanced age was somewhat unthought of and unexpected but an important source of pride. Conclusions These findings suggest that these oldest-old caregiving dyads are characterised by a relationship shaped by strong feelings of extended filial love, constituting a family feature that needs further understanding. Findings also underscore the challenges these carers face in dealing with several agents (secondary caregivers) and entities in the care provision. [ABSTRACT FROM AUTHOR]

Aim: Vesicoureteral reflux (VUR) is an important risk factor for urinary tract infection (UTI). We aimed to investigate the relationships between VUR and ultrasound with late dimercaptosuccinic acid (DMSA) scan findings in children aged older than two years who had their first febrile UTI (FUTI). Materials and Methods: Data from those patients with their first FUTI were retrospectively analyzed. A late DMSA scan was performed at least 6 months after an acute FUTI. The late DMSA scans were graded as mild (focal defect in uptake), moderate (uptake of renal radionuclide from 20 to 40%), and severe (shrunken kidney with uptake less than 20%). Micturating cystourethrography was performed at 3 to 6 weeks after the FUTI. Results: The records of 220 patients (61 mild VUR, 60 severe VUR, 99 without VUR) were reviewed. An abnormal US was more common in those patients with VUR than those without VUR (p=0.009). Abnormal US had a sensitivity of 79.34% for VUR and 81.67% for severe VUR. The negative predictive value of renal US for severe VUR was 91.13%. The frequency of renal scarring was higher in those patients with VUR than for those without VUR (102/44, p=0.001). A logistic regression analysis showed significant associations between abnormal US and VUR or severe VUR (p=0.019 and p=0.011, respectively). Renal scarring had a sensitivity of 84.3% for VUR, and 91.67% for severe VUR. Conclusion: Late DMSA scan findings can predict the presence and grade of VUR in older children who have their first FUTI. Normal renal US can predict the absence of severe VUR.

We investigated the recent epidemiology and characteristics of influenza-related hospitalization in Japanese children. This study included 3741 children with influenza. Children hospitalized for febrile seizures (FS) induced by etiologies other than influenza also served as a disease control. Most outpatients (92.8%) visited our hospital with complaints of respiratory symptoms, whereas FS were the most predominant symptoms of inpatients (58/154, 37.7%). Children with influenza-induced FS were significantly older than those with FS induced by other etiologies (P <0.001). Although the characteristics of severe influenza may vary throughout the world, the analysis of influenza-induced neurological disorders is important for understanding its epidemiology.

Objective: To evaluate the efficacy of ultra-early rehabilitation on elbow function after Slongo's external fixation for supracondylar humeral fractures in older children and adolescents. Methods: We retrospectively analyzed clinical data from 49 older children (> 8 years) and adolescents with supracondylar humerus fracture who were treated with Slongo's external fixation in our hospital from January 2016 to August 2020. Twenty-three patients received ultra-early postoperative rehabilitation (rehabilitation group) and 26 patients were not subjected to postoperative rehabilitation (control group). Time to ROM required for functional activity of daily living(ROM-ADL) in both groups was recorded postoperatively. Patients were followed up at 3 and 6 months after surgery to compare the elbow range of motion (ROM) and carrying angle (CA). Postoperative complications were assessed in both groups. Flynn scores and modified Mayo Elbow Performance Scores were also performed. Results: The elbow function at 6 months after surgery was significantly better than that at 3 months in the control group (P = 0.32). Time to ROM-ADL in the rehabilitation group was significantly shorter than that of the control group (P = 0.028). The elbow function, Flynn scores, and modified Mayo scores in the rehabilitation group at 3 and 6 months after surgery were significantly better than that of the control group (P(ROM, 3 months and 6 months) = 0.012 vs 0.039; P(Flynn scores, ROM, 3 months and 6 months) = 0.028 vs 0.005; P(Flynn scores, CA, 3 months and 6 months) = 0.032 vs 0.026; P(Modified Mayo scores, 3 months and 6 months) = 0.039 vs 0.024; respectively). There were no iatrogenic injuries, secondary fracture displacements, myositis ossificans, elbow deformities, or other complications in either group. One case of nail tract infection occurred in the rehabilitation group and was cured. Conclusion: Slongo's external fixation is a safe and effective surgical treatment for supracondylar humeral fractures in children over 8 years old and adolescents. Ultra-early rehabilitation treatment for postoperative children can significantly speed up the recovery after surgery. [ABSTRACT FROM AUTHOR]

Objective: The standard surgical treatment for supracondylar humeral fractures in children is closed reduction and percutaneous pinning. Given the need for greater fixation strength and higher risk of joint stiffness for children older than 8 years, external fixation is often performed for treating supracondylar humeral fractures in older children. The aim of this study was to compare the efficacy of lateral entry pins and Slongo's external fixation for treating supracondylar humeral fractures in older children. Methods: Children older than 8 years who underwent surgery for supracondylar humeral fractures at our hospital for surgery from January 2016 to December 2020 are to be retrospectively assessed. One group (n = 36) underwent internal fixation and percutaneous pinning with three lateral Kirschner wires, and the other group (n = 32) underwent Slongo's external fixator surgery. The demographic data, operation duration, number of fluoroscopies, and fracture healing time were compared between both groups. The elbow joint function was evaluated 6 months after the surgery on the basis of fracture healing time, lifting angle, elbow joint range of motion (ROM), and Flynn score. The incidence of postoperative complications was also recorded. Results: There was no significant difference between the two patient groups in terms of the demographic parameters. Compared to external fixation surgery, Kirschner wire surgery required shorter duration and fewer fluoroscopies (P < 0.05). Nevertheless, the fracture healing time was significantly less (P < 0.05), and the elbow ROM and Flynn scores were higher in the external fixator group compared to the Kirschner wire fixation group (P < 0.05). There was one case of secondary fracture displacement in the Kirschner wire group and one of pin tract infection in the external fixator group. No other iatrogenic injuries or complications were observed. Conclusion: Maybe Slongo's external fixator is a suitable alternative treatment option for supracondylar humeral fractures in children older than 8 years since it can achieve better fixation strength and early restoration of elbow joint movement with a lower risk of joint stiffness.

All children were treated with percutaneous Kirschner wire fixation and external fixation with plaster. Operation indexes, complications and wrist joint functions were compared between the two groups.Results: Operation time of PRMF group was shorter than that of LOR group (P < 0.05). Incision length in PRMF group was less than that in LOR group (P < 0.05). Bleeding volume of PRMF group was less than that of LOR group (P < 0.05). Incidence of complications in PRMF group was lower than that in LOR group.Conclusions: Compared with limited open reduction, it has better clinical effects of prying reduction with mosquito forceps in treatment of irreducible distal radius-ulna fractures in older children. This technique has the advantages of simple operation, less trauma, less bleeding and fewer complications, which is worthy of clinical promotion. [ABSTRACT FROM AUTHOR]

Aim: This study gathered views of 10 to 12-years-old pupils about their play experiences before and after transition to secondary school, comparing access to their right to play. Method: A multiple-case study design was used to gather views of six Year 6 primary pupils and six Year 7 secondary pupils living in the same community in the United Kingdom (UK). Six workshops, including a focus group, were conducted with each year group. Findings: Qualitative data from both focus groups were analysed thematically, individually and across year groups. Findings indicated that temporal, spatial and psychological factors affected both Year 6 and Year 7 pupils' play access. Year 6 pupils were more satisfied with their play opportunities and reported more time to play. Limitations: The small-scale size of this study limits drawing conclusions. Data were collected in the summer term and therefore the weather and point in the school year may have been influential. Conclusions: Findings suggested that, for the pupils involved, play opportunities appeared to decrease upon transition to secondary school. It is therefore important that barriers to play across age groups are considered and addressed, to ensure that all children can realise their right to play. Educational psychologists (EPs) can raise awareness of the benefits of play and the potential impact of limited play opportunities for older children. [ABSTRACT FROM AUTHOR]

We examined the correlation between initial Pirani and Dimeglio scores and their individual components to the number of casts for older clubfoot children. Twenty seven patients (39 feet) aged 2–11 years with idiopathic clubfeet were treated using the Ponseti technique and correlation with number of corrective casts calculated. The number of cast required was counted from application of primary cast to the time of initiation of the foot abduction orthosis. Average 8.45 ± 2.31 (range, 4–13) casts were used for treatment. A low correlation (r = 0.203) was identified when total Dimeglio score was compared with the number of casts. No correlation was identified for Pirani score (r = 0.023). Among individual components, only cavus deformity had a significant positive correlation to cast numbers. The Pirani and Dimeglio classifications still remain the most widely practiced clubfoot severity grading systems for the older clubfoot child. However, their prognostic value to predict the total cast duration from initial severity remains questionable. [ABSTRACT FROM AUTHOR]

A new recombinant norovirus GII.P16-GII.2 outnumbered pandemic GII.4 as the predominant GII genotype in the winter of 2016–2017 in Hong Kong, China. Half of hospitalized case-patients were older children and adults, including 13 young adults. This emergent norovirus targets a wider age population compared with circulating pandemic GII.4 strains.

Objective: Malformations of the lower limbs caused by hypophosphatemic rickets in older children are mostly complex, occurring on multiple planes without a single apex and showing arcuate bending of the diaphysis combined with torsion deformity, and are difficult to correct. This study retrospectively investigated the effect of and indicators for multi-segment osteotomy with interlocking intramedullary nail fixation in the treatment of bony deformity caused by hypophosphatemic rickets., Methods: The clinical data of 21 hypophosphatemic rickets patients seen between August 2007 and March 2022 were collected. The age range of the patients at the first surgery was 11 years and 1 month old to 15 years and 3 months old, with an average age of 12 years and 8 months. There were 6 males and 15 females. All patients had abnormal alignment of their lower limbs, with 32 limbs having varus deformity and 10 limbs having valgus deformity., Results: A total of 67 surgeries were performed across the 21 patients, including 24 cases of femoral osteotomy with antegrade intramedullary nail fixation, 6 cases of femoral osteotomy with retrograde intramedullary nail fixation, and 20 cases of tibial osteotomy with interlocking intramedullary nail fixation. A total of 34 limbs eventually underwent interlocking intramedullary nail fixation, 9 with genu valgum and 25 with genu varus. All 21 patients were followed up for a period of 14∼96 months, with an average of 42.6 months. The ends of the osteotomies achieved bony union in 4-9 months (average 6.8 months), after which normal weight-bearing walking could be resumed. No infection, vascular or neurological complications, or nonunion occurred. During postoperative follow-up, the alignment the lower limbs passed through zone 1 in 13 limbs, zone 2 in 12 limbs, and zone 3 in 5 limbs. The overall rate of an excellent effect was 83.3%., Conclusion: For lower limb deformity caused by hypophosphatemic rickets in older children, multi-segment osteotomy and strong fixation with interlocking intramedullary nails can achieve good correction outcomes., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2024 Lu, You and Wang.)

Objective: To determine the performance of late dimercaptosuccinic acid (DMSA) renal scans in identifying high-grade (III-V) vesicoureteral reflux (VUR) in children aged over 3 y with a febrile urinary tract infection (fUTI) history that has not been timely investigated.Methods: In this retrospective study of diagnostic accuracy, the clinical records of children aged between 3 and 18 y with fUTI history evaluated consecutively at Nephrology Unit of Hospital General de Niños Pedro de Elizalde, Argentina between 2006 and 2016 were reviewed. Patients with previously diagnosed renal or urinary tract abnormalities or who underwent previous postnatal genitourinary imaging were excluded. Only those assessed by renal and bladder ultrasound (RBUS), voiding cystourethrogram (VCUG) and late 6-mo DMSA scan were analyzed. The ability of the scintigraphy in identifying high-grade VUR was determined by comparing its findings with those of VCUG.Results: In 122 children (median age 5.37 y, 88.5% girls) RBUS was abnormal in 53 (43.4%) and 58 (47.5%) had VUR (30 of high-grade). Abnormal DMSA scan findings (70 patients, 57.4%) were associated with all grade (p = 0.00001) and with high-grade VUR (p = 0.00001). Sensitivity, specificity, negative (NPV) and positive (PPV) predictive values of late DMSA scans for all grades VUR were 93.1%, 75%, 92.3% and 77.1%, respectively. Only 4 patients with low-grade VUR had normal scans. For high-grade VUR, sensitivity and NPV reached 100%.Conclusions: In older children, the normal late DMSA scan predicted the absence of high-grade VUR, obviating the need for a VCUG. This approach could be a possible strategy for children not studied at acute infection time. [ABSTRACT FROM AUTHOR]

Lipoblastoma is a rare benign mesenchymal tumor of embryonic fat that occurs almost exclusively in infants and children. It accounts for less than 1% of childhood neoplasms and is found in slightly higher frequency in males compared to females. Lipoblastomas most commonly occur in the extremities and show variable rates of growth. Surgical excision is the treatment of choice and has an excellent prognosis although recurrences are possible. We report two cases of lower extremity lipoblastoma at 7 and 8 years of age. Both patients presented with a slow-growing painless mass over the thigh with no limitation in the range of motion of the joints of the affected limb. Plain films showed well-demarcated soft tissue masses. Cytological examination was suggestive of lipoblastoma which was later confirmed by histopathology examination. Complete surgical excision with meticulous dissection and preservation of vital neurovascular structures was done in both cases. No recurrence has been observed after 5 years of follow-up. Lipoblastomas should be considered as a possible diagnosis in older children presenting with a solid slow-growing soft tissue mass. [ABSTRACT FROM AUTHOR]

Background: Occlusion therapy is effective in older children with amblyopia. Objective: To evaluate and compare visual outcomes in older children aged between 9 and 18 years with unilateral refractive amblyopia after treatment with patching and/or optical correction. Settings and Design: Prospective randomized controlled study. Materials and Methods: Sixty children (9-18 years) with unilateral refractive amblyopia (anisometropic/meridional) with best-corrected visual acuity (BCVA) ≤6/12 (0.3 logMAR) in the worse eye were 1:1 randomized into nonocclusion and occlusion group. Both treatment groups underwent 4 weeks refractive adaptation period (RAP) and three follow-up visits at 6 weeks interval. After RAP, the better eye in the occlusion group was patched for 6 h daily, while the nonocclusion group children continued to wear spectacles for 18 weeks. BCVA (logMAR) at each visit was compared with the baseline reading. Statistical Analysis Used: Descriptive and inferential statistical analyses were used. Student′s t-test and Chi-square/Fisher exact test was used to calculate the P value. Results: There was a significant improvement in BCVA from baseline to 18 weeks after RAP within both treatment groups (P < 0.001) and significant higher proportion of children in occlusion group showed three lines of improvement compared with nonocclusion group (P = 0.011). Improvement in BCVA from baseline to 18 weeks was noted irrespective of the severity of amblyopia and age of the participants more so in occlusion group. Conclusion: Occlusion therapy is an effective and better treatment than only spectacle correction in children aged between 9 and18 years, with unilateral refractive amblyopia.

Individuals with autism spectrum disorder (ASD) often exhibit motor deficits that increase their risk of falls. There is a lack of understanding regarding gait biomechanics demonstrated by older children with ASD. The purpose of the study was to determine differences in gait patterns between older children with ASD and typically developing children. Eleven children with ASD and 11 age- and gender-matched typically developing children were recruited for the study. Participants walked on a force-instrumented treadmill at a constant speed (1.1 ​m/s ​- ​1.2 ​m/s) for five minutes (min). Participants performed maximal voluntary contractions to assess their knee muscular strength. Differences between individuals with ASD and matched control participants were examined through paired t -tests with a significance level of p  ​≤ ​0.05. Individuals with ASD demonstrated a smaller knee extensor torque compared to controls ( p  ​= ​0.002). Participants with ASD exhibited a shorter stride length ( p  ​= ​0.04), a greater cadence ( p  ​= ​0.03), and a higher variation in stride width ( p  ​= ​0.04) compared to control participants. The individuals with ASD experienced a greater braking ground reaction force ( p  ​= ​0.03) during loading response. The results indicate older children with ASD develop a unique gait pattern signified by a reduced stride length, increased cadence, and an increase of variation in stride width. This unique gait pattern may represent a movement strategy used by the individuals with ASD to compensate for the weakness associated with their knee extensor muscles. Individuals with ASD who demonstrate these unique gait deviations may face reduced postural stability and an increased risk of fall-related injuries., Competing Interests: All authors declare no conflict of interest., (© 2024 Chengdu Sport University.

This paper reviews information on why the nutrition of older children (5–9 years) and adolescents (10–19 years) is important and the consequences that it can have over generations. Developing countries still face a high burden of undernutrition and anemia, while the burden of overweight and obesity is on the rise in both developing and developed countries. There are evidence-based interventions which can improve the nutritional status and these include interventions for a balanced and diverse diet and micronutrient supplementation, especially iron and multiple micronutrient supplementation where there is sufficient evidence to reduce anemia. There is mixed evidence for the effective strategies to prevent and control obesity and a dearth of evidence from developing countries. Adolescent pregnancy also poses greater challenges to the health of mother and child, and advocacy should be rampant to delay the age of marriage and pregnancy. Interventions targeted to improving the nutritional status among “pregnant adolescents” have shown improvement in birth weight and a reduction in low birth weight and preterm delivery. Traditional platforms including school-based and community-based approaches offer a mixed picture of effectiveness, but emerging avenues of mHealth and social media could also be channelized to reach this population. The population of this age group is on the rise globally, and failure to invest in improving the nutrition of older children and adolescents will further increase the number of dependents in coming generations and negatively influence the health of future generations and progress of nations.

Objective: Through the preoperative surgical simulation in older children with developmental dislocation of the hip(developmental dysplasia of the hip, DDH), accurate osteotomy and rotation angle in operation, so as to achieve individualized treatment,improve the prognosis of the objective. Methods: The study was divided into two groups according to preoperative planning methods, one group was conventional surgery group, the other group was simulated operation group. A total of 20 cases were treated with pelvic triple osteotomy combined with femoral osteotomy. 10 cases in the traditional operation group and 10 cases in the simulated operation group,the average age of the operation was 11.3 years, and the average follow-up time was 24.2 months. All patients had pelvic reconstruction CT examination before the surgery, measure the CE angle, femoral anteversion angle and acetabular index. In the Mimics software, a simulated surgical procedure was performed to determine the angle of rotation and the location of the pelvic osteotomy in the operation of the femoral osteotomy, and the procedure was performed according to the outcome of the simulated operation. The preoperative evaluation indexes were graded by Tonnis, and the improved Trevor scoring system was used for postoperative evaluation. Results: In the simulated operation group, there were 4 Tonnis type 3 and 8 Tonnis type 4 hips. In the traditional surgery group, there were 4 Tonnis type 3 and 9 Tonnis type 4 hips. There was no significant difference in preoperative severity between the two groups. According to the Trevor score,8 hips(67%) were rated excellent, 3 hips(25%) were good, and 1 hips(8%) were fair in the simulated operation group. In the traditional surgery group, 5 hips(38%) were rated excellent, 5 hips(38%) were good, and 3 hips(23%) were fair. There was significant difference between the two groups. Complications: there were 3 cases of femoral head necrosis in different degree in the traditional operation group after operation.3 hips in the traditional surgery group had osteonecrosis of varying severity. Conclusions: The preoperative simulated surgery of older DDH can achieve accurate osteotomy and rotation angle, improve the prognosis of patients, and achieve individualized treatment of this kind of patients.

Community-acquired pneumonia causes substantial morbidity and mortality in sub-Saharan Africa with an estimated 131 million new cases each year. Viruses – such as influenza virus, respiratory syncytial virus and parainfluenza virus – are now recognised as important causes of respiratory disease in older children and adults in the developed world following the emergence of sensitive molecular diagnostic tests, recent severe viral epidemics, and the discovery of novel viruses. Few studies have comprehensively evaluated the viral aetiology of adult pneumonia in Africa, but it is likely to differ from Western settings due to varying seasonality and the high proportion of patients with immunosuppression and co-morbidities. Emerging data suggest a high prevalence of viral pathogens, as well as multiple viral and viral/bacterial infections in African adults with pneumonia. However, the interpretation of positive results from highly sensitive polymerase chain reaction tests can be challenging. Therapeutic and preventative options against viral respiratory infections are currently limited in the African setting. This review summarises the current state of the epidemiology, aetiology, diagnosis and management of viral pneumonia in sub-Saharan Africa.
