Bilateral Knee Lyme Arthritis in Children: A Report of 3 Cases.

CASES: Three patients presented with bilateral knee pain, effusion, decreased range of motion, and difficulty ambulating. Synovial analysis demonstrated leukocytosis in bilateral knees with positive serum enzyme-linked immunosorbent assay. All cases were managed with antibiotics and anti-inflammatories. One patient developed chronic Lyme arthritis and underwent arthroscopic synovectomy. CONCLUSION: Bilateral knee arthritis is a possible presentation of Lyme disease in children. Accurate diagnosis and treatment with antibiotics and anti-inflammatories can lead to satisfactory outcomes. Arthroscopic synovectomy may be indicated if conservative treatment fails.

Can You Trust What You Watch? An Assessment of the Quality of Information in Aesthetic Surgery Videos on YouTube.

BACKGROUND: Videos on YouTube can be posted without regulation or content oversight. Unfortunately, many patients use YouTube as a resource on aesthetic surgery, leading to misinformation. Currently, there are no objective assessments of the quality of information on YouTube about aesthetic surgery. METHODS: YouTube was queried for videos about the 12 most common aesthetic surgical procedures, identified from the 2015 American Society of Plastic Surgeons procedural statistics between May and June of 2016. The top 25 results for each search term were scored using the modified Ensuring Quality Information for Patients criteria based on video structure, content, and author identification. Average Ensuring Quality Information for Patients score, view count, and video duration were compared between authorship groups. RESULTS: A total of 523 videos were graded after excluding duplicates. The mean modified Ensuring Quality Information for Patients score for all videos was 13.1 (SE, 0.18) of a possible 27. The videos under the search "nose reshaping" had the lowest mean score of 10.24 (SE, 0.74), whereas "breast augmentation" had the highest score of 15.96 (SE, 0.65). Physician authorship accounted for 59 percent of included videos and had a higher mean Ensuring Quality Information for Patients score than those by patients. Only three of the 21 search terms had a mean modified Ensuring Quality Information for Patients score meeting criteria for high-quality videos. CONCLUSIONS: The information contained in aesthetic surgery videos on YouTube is low quality. Patients should be aware that the information has the potential to be inaccurate. Plastic surgeons should be encouraged to develop high-quality videos to educate patients.

Postoperative Prophylactic Antibiotics Reduce Surgical Site Infection Rates after Ventral Hernia Repair: A Systematic Review.

SSIs after ventral hernia repair (VHR) represent a significant complication. The impact of postoperative prophylactic antibiotics on the SSI rates after VHRs is unclear. A systematic review of PubMed and Web of Science databases from inception through March 2016 investigating the effect of postoperative prophylactic antibiotics after VHRs was performed. Strict inclusion and exclusion criteria were implemented, and the methodological quality of the included studies was assessed. After systematic independent assessment of 216 citations, four studies, involving 344 patients, met the inclusion criteria. Among the included studies, 164 patients received >24 hours of postoperative prophylactic antibiotics, whereas 180 patients were controls. The overall incidence of SSI among patients receiving postoperative antibiotics was 14.6 per cent (95% confidence interval [CI], 9.9 to 20.9) which compares favorably with the control group: 35.5 per cent (95% CI, 28.9 to 42.7) (odds ratio: 0.3, 95% CI: 0.2 to 0.5, P < 0.01). Among patient's receiving postoperative antibiotics, the pooled average duration of postoperative antibiotic treatment was 6.2 ± 0.4 days. Based on the available evidence, the use of postoperative prophylactic antibiotics seems to be associated with lower SSI rates after VHRs. Future prospective randomized controlled trials should be conducted to further confirm the efficacy of this prophylactic intervention.

An Algorithmic Approach to the Management of Ballistic Facial Trauma in the Civilian Population.

Annual incidence of non-fatal ballistic civilian has been increasing for the last decade. The aim of the present study was to clarify the optimal reconstructive management of civilian ballistic facial injuries. A systematic review of PubMed was performed. Articles were evaluated for defect type and site, reconstructive modality, complications, and outcomes. A total of 30 articles were included. Most common region of injury was mandibular with a 46.6% incidence rate. All-cause complication rate after reconstruction was 31.0%. About 13.3% of patients developed a postoperative infection. Gunshot wounds had overall lower complication rates as compared with shotgun wounds at 9.0% and 17.0%. By region, complications for gunshot wounds were 35% and 34% for mandible and maxilla, respectively. Immediate surgical intervention with conservative serial debridement is recommended. However, for patients with pre-existing psychiatric disorders, secondary revisions should be delayed until proper psychiatric stabilization. When there is extensive loss of soft tissue in the midface, aesthetic outcomes are achieved with a latissimus dorsi or anterolateral thigh free flap. Radial forearm flap is favored for thin lining defects. Open reduction is suggested for bony-tissue stabilization. The fibula flap is recommended for bony defects >5 cm in both midface and mandible. For bony defects, <5 cm bone grafting was preferred. Delaying bone grafting does not worsen patient outcomes. Surgical treatment of ballistic facial trauma requires thorough preparation and precise planning. An algorithm that summarizes the approach to the main decision points of surgical management and reconstruction after ballistic facial trauma has been presented in this study.

Statin-Associated Myopathy in a Pediatric Preventive Cardiology Practice.

OBJECTIVES: To describe muscle-related statin adverse effects in real-world pediatric practice. STUDY DESIGN: Using prospectively collected quality improvement data from a pediatric preventive cardiology practice, we compared serum creatine kinase (CK) levels among patients prescribed and not prescribed statins, and pre-/poststatin initiation. Multivariable mixed-effect models were constructed accounting for repeated measures, examining the effect of statins on log-transformed CK (lnCK) levels adjusted for age, sex, weight, season, insurance type, and race/ethnicity. RESULTS: Among 1501 patients seen over 3.5 years, 474 patients (14?±?4 years, 47% female) had at least 1 serum CK measured. Median (IQR) CK levels of patients prescribed (n?=?188 patients, 768 CK measurements) and not prescribed statins (n?=?351 patients, 682 CK measurements) were 107 (83) IU/L and 113 (81) IU/L, respectively. In multivariable-adjusted models, lnCK levels did not differ based on statin use (??=?0.02 [SE 0.05], P?=?.7). Among patients started on statins (n?=?86, 130 prestatin and 292 poststatin CK measurements), median CK levels did not differ in adjusted models (? for statin use on lnCK?=?.08 [SE .07], P?=?.2). There was a clinically insignificant increase in CK over time (??=?.08 [SE .04], P?=?.04 per year). No muscle symptoms or rhabdomyolysis were reported among patients with high CK levels. CONCLUSIONS: In a real-world practice, pediatric patients using statins did not experience higher CK levels, nor was there a meaningful CK increase with statin initiation. These data suggest the limited utility to checking CK in the absence of symptoms, supporting current guidelines.

Correlates of Achieving Statin Therapy Goals in Children and Adolescents with Dyslipidemia.

OBJECTIVE: To determine the real-world effectiveness of statins and impact of baseline factors on low-density lipoprotein cholesterol (LDL-C) reduction among children and adolescents. STUDY DESIGN: We analyzed data prospectively collected from a quality improvement initiative in the Boston Children's Hospital Preventive Cardiology Program. We included patients ≤21 years of age initiated on statins between September 2010 and March 2014. The primary outcome was first achieving goal LDL-C, defined as <130 mg/dL, or <100 mg/dL with high-level risk factors (eg, diabetes, etc). Cox proportional hazards models were used to assess the impact of baseline clinical and lifestyle factors. RESULTS: Among the 1521 pediatric patients evaluated in 3813 clinical encounters over 3.5 years, 97 patients (6.3%) were started on statin therapy and had follow-up data (median age 14 [IQR 7] years, 54% were female, and 24% obese, 62% with at least one lifestyle risk factor). The median baseline LDL-C was 215 (IQR 78) mg/dL, and median follow-up after starting statin was 1 (IQR 1.3) year. The cumulative probability of achieving LDL-C goal within 1 year was 60% (95% CI 47-69). A lower probability of achieving LDL-C goals was associated with male sex (HR 0.5 [95% CI 0.3-0.8]) and higher baseline LDL-C (HR 0.92 [95% CI 0.87-0.98] per 10 mg/dL), but not age, body mass index percentile, lifestyle factors, or family history. CONCLUSIONS: The majority of pediatric patients started on statins reached LDL-C treatment goals within 1 year. Male patients and those with greater baseline LDL-C were less likely to be successful and may require increased support.

In-Clinic Blood Pressure Prediction of Normal Ambulatory Blood Pressure Monitoring in Pediatric Hypertension Referrals.

OBJECTIVE: Since younger patients have low pretest probability of hypertension and are susceptible to reactive and masked hypertension, ambulatory blood pressure monitoring (ABPM) can be useful. To better target use in referred patients, we sought to define in-clinic systolic blood pressure (SBP) measures that predicted normal ABPM and target end organ damage. DESIGN, SETTING, PATIENTS, OUTCOME MEASURES: Data were collected on consecutive patients referred for high BP undergoing an ambulatory BP monitor from 2010 to 2013 (n = 248, 33.9% female, mean age 15.5 ± 3.6 years). Candidate in-clinic predictors were systolic maximum, minimum, or average BPs obtained by auscultative, oscillometric, or both. Multivariable logistic regression models were used to determine the prediction of normal ABPM by in-clinic BP predictors. Separate models considered predicting left ventricular hypertrophy (LVH) by in-clinic SBP vs. ABPM-defined hypertension. Identified predictor utility was tested with receiver operator characteristic curves. RESULTS: Maximum (OR 0.97 [95% CI 0.94-0.99]; P = .047), minimum (0.96 [0.94-0.99]; P = .002), and average (0.97 [0.95-1.00]; P = .04) in-clinic auscultative SBP predicted normal ABPM. Each had a c-statistic of 0.58. LVH was associated with in-clinic auscultative minimum SBP treated continuously (1.05, [1.01-1.10], P = .01) or dichotomized at the 90th percentile (8.23, [1.48-45.80], P = .02), as well as ABPM-defined hypertension (3.31, [1.23-8.91], P = .02). Both predictors had poor sensitivity and specificity. CONCLUSION: In youth, normal auscultative in-clinic systolic blood pressure indices weakly predicted normal ambulatory blood pressure and target end organ damage.

Aortic Stiffness in Youth with Hypertrophic Cardiomyopathy Genotype.

Clinical events in hypertrophic cardiomyopathy (HCM) patients are related to the degree of hypertrophy. Aortic stiffness in adult HCM patients has been reported to be higher than control patients. Increased stiffness may cause more LV hypertrophy and thus lead to more clinical events. We sought to (a) noninvasively compare aortic structure and function between youth with sarcomeric HCM genotype versus control youth and (b) explore the relation between aortic function and degree of left ventricular (LV) hypertrophy. In a prospective study from a single referral center, clinical, anthropometric, and hemodynamic data were acquired on 28 consecutive pathogenic HCM gene mutation carriers and 26 unrelated controls (mean age 16.3, 50 % girls). Hemodynamic data included applanation tonometry measured central pulse pressure, carotid-femoral pulse wave velocity (CFPWV), reflected wave augmentation index (AIx). In the HCM gene carriers, LV mass-to-volume ratio was extracted from clinically indicated echocardiograms as an index of hypertrophy. Associations were assessed using multivariable adjusted linear regression. The HCM group was comprised of 14 myosin binding protein C3 carriers, 13 myosin heavy chain 7 carriers, and 1 child with both. HCM and control groups did not differ by age, sex, height, body mass index, heart rate, or blood pressure. HCM carriers had significantly lower CFPWV than controls (4.46 ± 0.88 vs. 4.97 ± 0.44 m/s, p = 0.01) and higher AIx magnitude (27 ± 19 vs. 18 ± 7 %, p = 0.04). These associations persisted after adjustment for age, sex, height, heart rate, mean pressure, and medication use. Within the HCM group, LV hypertrophy was related to AIx but not CFPWV. CFPWV nor AIx differed by genotype. Aortic stiffness appears lower, but wave reflection appears higher in youth carrying HCM gene mutations. The degree of wave reflection appears correlated with LV hypertrophy in this high-risk cohort, suggesting that mitigation of wave reflection may possibly attenuate LV hypertrophy.

Pediatric lipid management: an earlier approach.

The National Heart, Lung and Blood Institute Expert Panel Integrated Guidelines promote the prevention of cardiovascular disease (CVD) events by encouraging healthy behaviors in all children, screening and treatment of children with genetic dyslipidemias, usage of specific lifestyle modifications, and limited administration of lipid pharmacotherapy in children with the highest CVD risk. These recommendations place children in the center of the fight against future CVD. Pediatric providers may be in a position to shift the focus of CVD prevention from trimming multiple risk factors to cutting out the causes CVD.
