The fracture pattern was categorized into undisplaced (n = 3), angulated-stable (n = 7) or displaced-unstable (n = 5) types. Five fractures were fixed in-situ using screws or Kirschner wires. Other five fractures were treated by closed reduction and screw fixation and the remaining five fractures were managed by femoral valgus osteotomy. Bony union was achieved, and prefracture ambulatory status was restored in all cases. A high index of suspicion is required in the diagnosis of undisplaced or angulated-stable fractures. Treatment is usually challenging, but a judicious approach considering the fracture pattern and patient characteristics result in successful outcomes. The angulated-stable pattern of fracture is unique in osteogenesis imperfecta patients and requires special attention.Pediatric forearm and wrist fractures are common; furthermore, some are displaced and require manipulation and reduction. The procedure is commonly performed without real-time image guidance and evaluated radiographically after reduction and casting, leading to multiple reduction attempts and malalignment. Although fluoroscopy can provide real-time assessment of fracture alignment during the procedure, it is not readily available in many emergency departments (EDs) and involves radiation exposure. Ultrasonography is an alternative real-time imaging modality that is inexpensive and readily available. The purpose of this study was to determine whether the use of real-time bedside sonography during closed reduction of distal and middle third forearm fractures can decrease the number of reduction attempts and reduce the number of patients requiring surgery. We compared the results of a conventional blind manipulation, fracture reduction, and casting to fracture reduction under real-time ultrasonographic guidance, in patients treated in our ED between 2014 and 2016. Overall, 458 patients with distal or middle third fractures were included. Of these reductions, 289 were performed without real-time imaging (group 1) and 169 under real-time ultrasound guidance (group 2). In group 1, 10% of patients required re-reduction, and 5% of patients needed surgery. In group 2, only one patient (0.6%) required re-reduction and 1% of patients required surgery due to fracture instability. In conclusion, the current study shows that real-time ultrasound-guided forearm fracture reduction is an effective and inexpensive method for correction of displaced forearm and wrist fractures in children, which does not involve any radiation exposure.
To investigate the subchondral bone surface of the distal femoral epiphysis and monitor the morphologic changes on ultrasonography (US) in growing children.
A total of 160 football players aged 9-11 years underwent ultrasonographic examination of both knees. The regularity of the subchondral bone surface of the femoral condyles was classified as grade 0 (smooth), 1 (focal semilunar depression or indentation) or 2 (broad irregularity). The relationship between age and frequency of irregularity was analyzed. Children with a grade 2 were referred for radiography and MRI to check for osteochondritis dissecans (OCD). All players underwent repeat examination 1 year later.
On initial examination, 82/320 knees (25.6%) were categorized as grade 0, 237/320 (74.1%) as grade 1 and 1 (0.3%) as grade 2. Logistic regression analysis revealed a significant association of increasing age with decreased irregularity of subchondral bone in the lateral and medial condyles (P = 0.019 and P < 0.001 for trend, respectively)distal femoral epiphysis and could be a useful screening tool for detecting OCD.
The most common treatment method for a fixed knee flexion contracture more than 10 degrees in cerebral palsy (CP) is distal femoral extension osteotomy (DFEO). However, a serious complication after a DFEO is neurological impairment. Its rates were reported as 5- 40%. Intraoperative neuromonitoring (IONM), widely used in spinal surgery and in other fields, is a valuable tool to define any neurological injury during operation. The aim of our study was to determine surgical steps with risk of neurological injury and to report if precautions would be effective in recovering signal loss.
We performed IONM during DFEO of 23 knees of 12 children with CP. IONM was performed by recording somatosensory evoked potentials, transcranial motor evoked potentials and free-run electromyography during defined steps throughout the surgery. Preoperative and postoperative popliteal angles, flexion contractures and physeal posterior distal femoral angles were evaluated.
We detected alert signals at osteotomy or manipulation steps of surgeries of all patients. We observed persistent alert signals in two cases (2 out of 23 knees; Group 2). In this group, the action potentials recovered only after 5 and 10 degrees of undercorrection at the osteotomy sites. Alert signals disappeared after a brief period of waiting in other cases. Throughout mean 37 months of follow-up, none of our patients experienced any neurological complication.
The study concludes that the surgical steps in DFEO with a higher risk for a neurological complication were the osteotomy and manipulation steps. Alert signals were detected with the help of IONM, and preventive measures were effective in recovering neuromonitoring recordings.

Sleep difficulties, daytime sleepiness, and sluggish cognitive tempo (SCT) are associated with impairments in academic performance. SCT refers to symptoms of sluggishness, tiredness/lethargy, and slowed thinking/processing, but despite symptom overlap with sleepiness, research examining interrelations of SCT with sleep and daytime sleepiness is limited. The aims of this study were to evaluate the relationship between SCT and daytime sleepiness and to examine pathways between sleep, daytime sleepiness, SCT, and academic performance.
Participants were a community sample of 1628 parents/caregivers of children aged between 6 and 10 years who completed questionnaires about their child's behavior, sleep, and academic performance. Confirmatory factor analysis was used to examine whether SCT was distinct from daytime sleepiness. Then, structural equation modeling was used to examine direct and indirect pathways between sleep (sleep-disordered breathing [SDB] symptoms, sleep duration, and latency), daytime sleepince.
Geant4 simulation is used to calculate peak efficiency and correct the effect of coincidence summing in detecting volumetric gamma-ray sources; this simulation was applied to a standard 152Eu source with different volumes as a test case. The source is a liquid cylindrical shape of various volumes. Peak efficiency was calculated using two tracks in the Geant4 simulation single-energy track and "monoenergetic Track" without coincidence summing. Here, the energy of the source is known, and the track of radionuclides, including the coincidence summing, depends on the decay scheme of the radioactive source. The ratio between the peak efficiency of the two tracks gives us the correction factor (CF). The experimental method was used to calculate the peak efficiency and was amended by the correction factor computed with Geant4 tracks. The results showed a good agreement between experimental efficiency after correction and free-summing simulated efficiency. The comparison indicated that the present method is valid adicated that the present method is valid and useful for voluminous gamma-ray sources.
Although the set point is one of the best understood weight defense mechanisms, how and when a set point is established and what causes its disruption are not well understood. The purpose of this review is to address these gaps in the literature by exploring studies on the establishment of the set point theory and the underlying metabolic processes that support its existence.
Research suggests that weight loss achieved through restricted energy intake and increased energy expenditure is difficult to maintain and is often followed by greater weight gain over time. It is hypothesized that such weight gain is driven by an individual's set point, a weight range in which the body seeks to remain by adjusting metabolism (e.g. VTX-27 in vitro by moderating energy expenditure based on energy intake in times of diet or energy fluctuation). Similar to adults, weight loss in adolescence results in decreased resting metabolic rate (RMR), and that the RMR remains suppressed even with weight restoration.
Recommending weight loss in youth results in metabolic adaptations to restore weight and weight inclusive approaches may be more appropriate to protect their health and wellbeing.

This review will update pediatric providers on the recent data regarding the epidemiology, diagnosis, and treatment of common skin infestations affecting children and adolescents.
Standard superficial skin biopsy for scabies and the vacuum method for head lice can increase diagnostic accuracy and efficiency. There is growing resistance to some of the traditional treatments for scabies and head lice, and progress has been made in finding newer and potentially more effective treatments, such as oral moxidectin for scabies and abametapir for head lice. Recent studies have established the safety of traditional treatments, such as permethrin and oral ivermectin in infants and small children.
Permethrin and ivermectin are both considered safe and effective for children and adolescents with scabies. Permethrin is generally considered safe in infants less than two months of age. Proper application of permethrin is critical, and providers should emphasize proper application technique. Treatment of head lice should only be initiated with active infestations. Resistance to permethrin continues to increase and other options are now available, including an over-the-counter topical ivermectin formulation. Identification and eradication of bed bug infestations are crucial in preventing bedbug bites.

The principal trend in acute coronary syndrome (ACS) is increasing utilization of percutaneous coronary interventions (PCI) and declining coronary artery bypass graft surgery (CABG) utilization. This study was designed to evaluate whether higher PCICABG ratios lead to higher in-hospital PCI or CABG mortality.
The National Readmission Database for years 2016 was queried for all hospitalized ACS patients who underwent coronary revascularization during their admission. The study population was derived from 355 US hospitals and included 103 021 patients. Hospitals were grouped based on their PCICABG ratio into low, intermediate, and high ratio quartiles with a median [interquartile ranges (IQR)] PCICABG ratio of 2.9 (2.5-3.2), 5.0 (4.3-5.9) and 8.9 (7.8-10.3), respectively multivariable logistic regression with adjustment for age, demographics and comorbidities were used to identify CABGPCI ratio related risk for in-hospital CABG and PCI mortality.
Higher PCICABG ratios correlated with an increased CABG mortality.
