Long-distance travel across multiple time zones presents unique challenges for patients taking insulin, requiring adjustments in both timing and dosage of basal insulin when several times zones (≥5) are traversed. Travel across the International Date Line adds to the confusion, as existing resources and dosing calculators often do not account for the date change. We review recommendations from available guidelines and dosage calculators used for long-distance travel basal insulin adjustments and then present our patient handouts which allow for a safe, specific, single dose adjustment for eastward and westward travel. The included handouts are easy to use and can be freely reproduced for use in diabetes clinics.

Following a demonstration that mouse-optimized cytosine-guanosine dinucleotide (CpG) oligodeoxynucleotides stimulated innate immune protection against intracellular pathogens, we tested the ability of CpG 7909, a primate-optimized Toll-like receptor 9 (TLR9) agonist, to stimulate rhesus macaques to produce interferon-

Continuous glucose monitoring (CGM), while a relatively new technology, has the potential to transform care for children with type 1 diabetes. Some, but not all studies, have shown that CGM can significantly improve hemoglobin A1c levels and reduce time spent in the hypoglycemic range in children, particularly when used as part of sensor-augmented pump (SAP) therapy. Despite the publication of recent clinical practice guidelines suggesting CGM be offered to all children 8 years of age or older who are likely to benefit, and studies showing that younger children can also benefit, this technology is not yet commonly used by children with type 1 diabetes. Effects of CGM are enhanced when used on a near-daily basis (a use-dependent effect) and with insulin pump therapy. Therefore, coordinated strategies are needed to help children and their families initiate and continue to use this resource for diabetes care. This review introduces CGM to pediatric endocrinologists who are not yet familiar with the finer details of this technology, summarizes current data showing the benefits and limitations of CGM use in children, reviews specific case examples demonstrating when CGM can be helpful, and shows the value of both retrospective and real-time CGM. It is hoped that this information leads to discussion of this technology in pediatric endocrinology clinics as an important next step in improving the care of children with type 1 diabetes.

The purpose of the study was to describe the early complications and delayed shoulder complaints of non-displaced or minimally displaced pediatric proximal humerus fractures treated non-operatively. Methods: Retrospective review of all pediatric proximal humerus fractures at a single institution from 2001 to 2016. Inclusion criteria were: AP and axillary radiographs upon presentation and final follow up, one follow up appointment, either a non-displaced or minimally displaced fracture, and open physis. Exclusion criteria were: pathologic fractures, re-fractures, bone metabolic disorders. Patient demographics, injury characteristics, radiographic measurements and clinical exam findings were reviewed. Delayed shoulder complaints were defined as a visit to any provider for an ipsilateral shoulder or arm complaint after final scheduled fracture appointment. Results: Sixty-nine of 177 total pediatric proximal humerus fractures met inclusion criteria. Mean age was 10 years (SD = 3.4). Sixty-five had angulation <20 degrees. Median time to last scheduled follow up was 1.4 months (Interquartile range 0.8-1.4). At last scheduled follow up, 9 (13.0%) fractures had an altered exam. One (1.4%) fracture had a complication of a fall and re-fracture. Extraphyseal fractures were more likely to increase in angulation at short term follow up, but had no association with short or long term complications. No patient initially treated with non-operative management subsequently underwent operative treatment. There were three presentations (4.3%) to health professionals for subsequent shoulder complaints; one was treated with short courses of physical therapy and the other two were simply observed. Conclusions: Non-displaced or minimally displaced proximal humerus fractures treated non-operatively sustain rare short or long term complications with no cross over to operative management. Once non-operative management is pursued, these fractures may be amenable to surveillance with primary care or allied orthopedic staff after initial evaluation by pediatric orthopedic providers.

IntroductionPrimary hypothyroidism is a well-known cause of poor linear growth in children. A rare finding with profound or long-standing disease is anterior pituitary enlargement (pituitary pseudotumor). This case highlights this uncommon finding, discusses clinical situations in which gradual dose escalation of levothyroxine may be advisable and reviews adjuvant therapies that have been previously attempted to improve final height in the setting of profound hypothyroidism.Case presentationWe report the case of a 13-year-old Hispanic girl initially evaluated for poor linear growth and delayed puberty, and found to have pituitary enlargement secondary to profound primary hypothyroidism. Treatment with progressive doses of levothyroxine normalized her symptoms and led to complete resolution of her pituitary findings, but she then rapidly progressed through puberty, achieving an adult height of only 142cm, significantly below her calculated mid-parental height.ConclusionsIn cases of severe primary hypothyroidism with prolonged elevation of thyroid-stimulating hormone and pituitary pseudotumor, gradual replacement of thyroid hormone with slowly escalating doses of levothyroxine may be beneficial to prevent complications of therapy. Early recognition and treatment of hypothyroidism during childhood is essential for normal growth, as final height is invariably compromised in children with prolonged disease. Additional study is needed to determine the potential beneficial effects of gonadotropin-releasing hormone agonist and recombinant human growth hormone treatment in this setting.

Pyogenic liver abscess is a rare complication of diabetes, usually seen in adults greater than 50 years of age who have had diabetes for many years. We describe an 18-year-old male with type 2 diabetes found to have a pyogenic liver abscess caused by Klebsiella pneumoniae, and show accompanying images from his evaluation for fever of unknown origin (FUO). We conclude that in a child or adolescent with FUO and diabetes, occult pyogenic liver abscess must be considered.

IntroductionRecently the EOS imaging system (EOS Imaging, Paris, France) has provided advancements in 3D spinal modeling. Advancements include low radiation as well as fast and accurate reconstructed measurements of spinal parameters. There is a paucity of studies analyzing the reproducibility of the EOS Imaging System and the sterEOS software in the production of 3D spinal models for children with adolescent idiopathic scoliosis (AIS). Objectives The purposes of the study were 1) to determine the intraclass correlation (ICC) for both the inter-observer and intra-observer in the measurements of Cobb angles in AP view as well as the Cobb angles in the lateral view; 2) to assess the ICC for inter-and intra-observer in the axial vertebral rotation (AVR) of the apex vertebra; 3) to compare differences of spinal parameters between two examiners and two trials; 4) to determine how long a 3D reconstruction of the spine takes. Methods Bilateral x-ray images of fifteen patients (age: 6 -15 years old, 5 males, 10 females) were retrospectively selected. These EOS images were uploaded into the sterEOS computer program. Within the software, spinal and pelvic parameters were identified manually to construct a 3D model of the spine. The sterEOS software calculates the Cobb angles, angles of lordosis, angles of kyphosis, and the AVRs of the apex vertebra. The 3D modeling was performed independently by two examiners. Each examiner modeled each patient's spine in two spaced out trials. The ICC between inter-and intra-observers were calculated and compared statistically. Results and discussionBoth the inter-and intra-observers showed excellent reproducibility for the Cobb angles in the proximal segment (ICC: 0.72 -0.91), kyphosis (ICC: 0.85-0.92), and lordosis (ICC: 0.82 -0.95). No significant differences were found between angle differences (0.35°to 2.4°). In contrast to the traditional radiography, the sterEOS provides a better high quality view within the sagittal plane. A moderate inter-observer ICC for the Cobb angle in the distal segment (ICC = 0.67) indicates the examiners have to carefully adjust the alignment and vertebrae in 3D rather than in 2D following the automatic computation from the EOS software. The interobserver ICC for the AVR in the lumbar region (0.80) is higher than the thoracic or thoracolumbar region (0.65), but with high differences of AVR (4.0°-6.3°). The average time that two examiners spent per subject ranged from 34.6 to 37.4 minutes. Conclusion and significance EOS provides significantly reliable and accurate spinal modeling in the measurement of children with AIS. Exposure to less radiation as compared to other radiographic modality allows EOS to offer acceptable quality view of the spine in the sagittal and transversal plane. sagittal balance and predictive equations to determine lumbopelvic compensatory patterns (LPCP). These equations are used to guide surgical decision making and technique selection. Although other lumbopelvic compensation equations are available, these have not been compared wi...
