Abstract: The purpose of this article is to describe the activities developed within the framework "Regional Workshop on Optimization of Protection in Pediatric Interventional Radiology in Latin American and Caribbean countries," developed between October 16th and 19th of the year 2023 in the city of San José, Costa Rica. The workshop was carried out as part of a joint work between the Pan American Health Organization (PAHO) and the World Health Organization (WHO), in cooperation with the International Atomic Energy Agency (IAEA). The main objective of the regional workshop was to gather the experiences and future work planning among participants in the Optimization of Protection in Pediatric Interventional Radiology in Latin America and the Caribbean (OPRIPALC) program. It involved professionals from 14 centers across 11 countries in the region, along with 4 experts from PAHO/WHO/IAEA. The work modalities during the workshop consisted of keynote presentations, individual presentations, group work, and general discussions. An online survey was carried out after the workshop, with the objective of knowing the opinion of the event participants and determining the impact and projection of the OPRIPALC program. During the workshop the centers had to present their experiences: the use of the DOLQA dose management system was presented and work was done on the consensus document on good practices. The activities, topics and organization of the workshop were valued positively by the participants. There is unanimity among the centers that the OPRIPALC program has had a positive impact and they wish to continue actively participating in the next biennium., (Copyright © 2024 Health Physics Society.)

As a mainstay of treatment for acute lymphoblastic leukemia (ALL), vincristine's side effect profile is well known. Parallel administration of the antifungal fluconazole has been shown to interfere with the metabolism of vincristine, potentially resulting in increased side effects. We conducted a retrospective chart review to determine whether concomitant administration of vincristine and fluconazole during pediatric ALL induction therapy impacted the frequency of vincristine side effects, namely, hyponatremia and peripheral neuropathy. We also evaluated whether the incidence of opportunistic fungal infections was impacted by fluconazole prophylaxis. Medical charts of all pediatric ALL patients treated with induction chemotherapy at Children's Hospital and Medical Center in Omaha, NE, from 2013 to 2021 were retrospectively reviewed. Fluconazole prophylaxis did not significantly impact the rate of fungal infections. We found no correlation between fluconazole use and increased incidence of hyponatremia or peripheral neuropathy, which supports the safety of fungal prophylaxis with fluconazole during pediatric ALL induction therapy., Competing Interests: The authors declare no conflict of interest., (Copyright © 2023 Wolters Kluwer Health, Inc.

Approved direct-acting antiviral (DAA) regimens against hepatitis C virus (HCV) can cure nearly all patients; however, socioeconomic disparities may impact access and outcome. This study assesses socioeconomic factors, differences in insurance coverage and the drug prior authorization process in HCV-infected patients managed in community practices partnered with a dedicated pharmacy team with expertise in liver disease. This Institutional Review Board-approved, ongoing study captures data on a cohort of 2480 patients from community practices. Patients had chronic hepatitis C and were treated with DAA regimens selected by their physician. The HCV Health Outcomes Centers Network provides comprehensive patient management including a dedicated pharmacy support team with expertise in the prior authorization process. In this cohort, 60.1% were male, 49% were Hispanic Whites (HW), 37% were Non-Hispanic Whites (NHW), and 14% were Black/African American (BAA). Eighty-seven percent of patients were treatment-naïve, 74% were infected with genotype 1 virus and 63% had advanced fibrosis/cirrhosis (F3/F4 = 68.2% HW, 65.6% BAA, 55.4% NHW). Forty percent of patients were on disability with the highest percentage in the BAA group and less than one-third were employed full time, regardless of race/ethnicity. Medicare covered 42% of BAA patients versus 32% of HW and NHW. The vast majority of HW (80%) and BAA (75%) had a median income below the median income of Texas residents. Additionally, 75% of HW and 71% of BAA had median income below the poverty level in Texas. Despite the above socioeconomic factors, 92% of all prior authorizations were approved upon first submission and patients received DAAs an average of 17 days from prescription. DAA therapy resulted in cure in 95.3% of patients (sustained virologic response = 94.8% HW, 94.0% BAA, 96.5% NHW). Despite having more advanced diseases and more negative socioeconomic factors, >94% of HW and BAA patients were cured. Continued patient education and communication with the healthcare team can lead to high adherence and > 94% HCV cure rates regardless of race/ethnicity or underlying socioeconomic factors in the community setting., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2023 the Author(s).

Both overfeeding and underfeeding critically ill children are problematic. This prospective pilot study evaluated the resting energy expenditure in infants and children requiring extracorporeal membrane oxygenation (ECMO) support. An indirect calorimeter was used to measure oxygen consumption (VO 2 ) and carbon dioxide production (VCO 2 ) from the mechanical ventilator. Blood gases were used to determine VO 2 and VCO 2 from the ECMO circuit. Values from the mechanical ventilator and ECMO circuit were added, and the resting energy expenditure (REE) (Kcal/kg/day) was calculated. Measurements were obtained > 24 hours after ECMO support was initiated (day 2 of ECMO), 1 day before ECMO discontinuation or transfer, and 1 day after decannulation. Data were compared with the predicted energy expenditure. Seven patients aged 3 months to 13 years were included. The REE varied greatly both above and below predicted values, from 26 to 154 KCal/kg/day on day 2 of ECMO support. In patients with septic shock, the REE was > 300% above the predicted value on day 2 of ECMO. Before ECMO discontinuation, two of six (33%) children continued to have a REE > 110% of predicted. Three patients had measurements after decannulation, all with a REE < 90% of predicted. REE measurements can be obtained by indirect calorimetry in children receiving ECMO support. ECMO may not provide metabolic rest for all children as a wide variation in REE was observed. For optimal care, individual testing should be considered to match calories provided with the metabolic demand., Competing Interests: Disclosure: The authors have no conflicts of interest to report., (Copyright © ASAIO 2022.)

Bronchial thermoplasty (BT) is one of the novel approved modalities in treating severe asthmatics to overcome their exacerbating symptoms such as increased anxiety. The purpose of this study was to evaluate anxiety level among severe asthmatics while undergoing BT procedure. This was an observational study where subjects self-evaluated their overall anxiety level using the burns anxiety inventory (BAI) questionnaire at baseline and prior to each of three BT treatments (broncho thermoplasty procedure 1, broncho thermoplasty procedure 2, and broncho thermoplasty procedure 3). The BAI questionnaire consisted of three different categories with each category having specific symptoms. Categories were grouped as: Anxious feelings, Anxious thoughts, and Physical symptoms. Subjects' Asthma Control Tests were also collected for analysis before and after the BT procedure. A total of 17 subjects with a mean age of 55.9 ± 14.5 years participated in the study. Fifty three percent were females (n = 9) and 41.2% (n = 7) were on prescribed anxiety medications. There was a significant drop in the patients' overall BAI anxiety level over time, P < .0001, in Anxious feelings (P = .0001), anxious thoughts (P = .001), and physical symptoms (P = .025). When analyzing the change in anxiety level among those who were not on prescribed anxiety medications, significant drop in overall anxiety level and in the subcategories were also noted. (P < .05). In addition, ACT scores showed a significant improvement (post vs pre) (18.5 ± 4.0 vs 13.3 ± 6.3, P = .03; Cohen's d = 0.73). This study shows the effectiveness of BT in decreasing severe asthmatic anxiety levels from baseline to last BT treatment and this benefit was mostly noted in those who were not on any anxiety medications. A limitation of this study is that all subjects were recruited from a single center. Therefore, to further validate the study findings, a multi-center study needs to be conducted with a larger sample size., Competing Interests: LDT is a speaker/consultant for AstraZeneca, Boehringer Ingelheim, Regeneron, Sanofi Genzyme, Novartis and Boston Scientific.

Objective: The aim of this study was to quantify the impact of electronic health record (EHR) workstation single sign-on (SSO) for nurses., Background: SSO was implemented in 19 hospitals for expedited EHR access., Methods: Login durations before and after SSO implementation were compared, and the financial value of nursing time liberated from keyboard was estimated. Stratified analyses show time liberated and financial value by staffing level and system size., Results: First-of-shift login was reduced by 5.3 seconds (15.3%) and reconnect duration was reduced by 20.4 seconds (69.9%). SSO liberated 27,962.4 hours of nursing time from keyboard login per year across 19 facilities, and 1,471.7 hours/year/facility, valued at $52,112/facility and $990,128 for 19 hospitals. Time value ranges from $201,835 per year for a 5-hospital system with 300 nurses per facility to $672,790 per year for a 10-facility system with 500 nurses per hospital., Conclusions: Nurses gained substantial time liberated from EHR keyboard by SSO for patient care, having significant financial value for the organization.

The aim of this study was to obtain real-world, US, observational data on the effect of baseline resistance-associated substitutions (RASs) on achieving sustained virologic response (SVR) in hepatitis C (HCV) patients treated with direct-acting antiviral (DAA) regimens; the need for long-term follow-up in post-SVR patients.It is uncertain if the presence of RASs limits efficacy to DAAs. Once SVR is achieved, society guidelines recommend long-term surveillance for hepatocellular carcinoma in certain patients. Real-world data are limited on these topics.Adult patients treated with DAAs at community hepatitis clinics between January 2015 and April 2017 were included in this study. Baseline resistance testing was performed before treatment. Per guidelines, post-SVR long-term monitoring was required in patients with F3 to F4 fibrosis before treatment or with elevated ALT levels (>19 U/L females; >30 U/L males).A total of 875 chronic, mostly GT1a (60%) HCV patients were treated with an approved DAA regimen. Average baseline AST and ALT were 75 and 67 U/L, respectively, and 47% had F3 to F4 fibrosis at baseline. SVR was achieved in 863 (98.6%) patients despite a high presence of baseline RASs (61%). Long-term monitoring was required post-SVR in 539 patients (62%).In a real-life, US cohort of HCV-infected patients, nearly all patients achieved SVR with available DAA regimens regardless of baseline RASs. Approximately two-thirds of these patients required long-term follow-up, despite viral eradication.

Study Design: Ovine in vivo study., Objective: To perform lateral approach lumbar surgery in an ovine model to administer an injectable riboflavin cross-linked high-density collagen (HDC) gel and to assess its ability to mitigate intervertebral disc (IVD) degeneration after induced annulus fibrosus (AF) injury., Summary of Background Data: Biological-based injectable gels have shown efficacy in restoring biomechanical, radiographic, and histological parameters in IVD-injured animal models. Riboflavin cross-linked HDC gel has previously demonstrated retention of nucleus pulposus (NP) tissue, reduced loss of disc height, and prevention of terminal cellular degenerative changes in rat-tail spines. However, this biological therapy has never been tested in large animal models., Methods: Forty lumbar IVDs were accessed from eight sheep via lateral approach surgery. IVDs were randomly assigned to healthy control, injury and HDC treatment, or negative control with injury and no treatment. IVD injury was carried out using a drill-bit through the AF followed by needle puncture of the NP. Sheep were followed for 16 weeks and underwent qualitative/quantitative magnetic resonance imaging, x-ray, and histological analyses of collagen and proteoglycan content., Results: The lateral approach to the ovine lumbar spine to deliver HDC gel proved to be safe and reproducible. IVDs treated with the HDC gel revealed less degenerative changes at the microscopic level based on AF and NP histology. However, mean Pfirrmann grade, T2 relaxation time, NP voxel size, and disc height index were not significantly different between the two injury groups., Conclusion: Injectable HDC gel can be administered safely via lateral approach surgery in an ovine AF injury model. IVDs treated with HDC gel demonstrated less degeneration at the microscopic level though radiographic changes were slight when comparing treated to untreated IVDs. Future studies will need to elucidate the role of injury technique and time frame for follow-up in correlating histological and radiographical outcomes., Level of Evidence: N /A.

Background: Numerous techniques for the surgical management of lambdoidal synostosis have been previously described; however, no best practice technique currently exists. Surgical procedures range from complete posterior calvarial reconstruction to distraction osteogenesis techniques. Our primary purpose is to describe a novel approach to correct unilateral or bilateral lambdoidal synostosis., Methods: A retrospective review was performed on a single surgeon's experience with craniosynostosis (1994-2014). Specifically, craniosynostosis cases involving the lambdoidal suture, which were repaired using a novel 'tongue and groove' technique, were identified., Results: A total of 664 craniosynostosis cases were retrieved, with 21 primarily involving the lambdoidal suture (3.2%). Of these, 18 were unilateral and 3 were bilateral lambdoidal synostosis. Male-to-female ratio was 3:1. Average age of first encounter with a craniofacial physician was 33 weeks (8 months). Average age at time of surgery was 43 weeks (10.75 months). Complications of this technique included 1 patient who experienced refusion of his lambdoidal suture and fusion of his sagittal suture, and 4 who returned for bone graft coverage of full-thickness calvarial defects owing to a lack of complete reossification., Conclusion: The "tongue and groove" technique represents a novel method for the management of lambdoidal synostosis with good esthetic outcomes, allowing immediate cranial stabilization with increased skull volume. This technique, used by the senior author for >20 years, provides a reproducible and reliable method of correcting lambdoidal synostosis.

Background: Congenital heart disease (CHD) has a multifactorial pathogenesis, but a genetic contribution is indicated by heritability studies. To investigate the spectrum of CHD with a genetic pathogenesis, we conducted a forward genetic screen in inbred mice using fetal echocardiography to recover mutants with CHD. Mice are ideally suited for these studies given that they have the same four-chamber cardiac anatomy that is the substrate for CHD., Methods and Results: Ethylnitrosourea mutagenized mice were ultrasound-interrogated by fetal echocardiography using a clinical ultrasound system, and fetuses suspected to have cardiac abnormalities were further interrogated with an ultrahigh-frequency ultrasound biomicroscopy. Scanning of 46 270 fetuses revealed 1722 with cardiac anomalies, with 27.9% dying prenatally. Most of the structural heart defects can be diagnosed using ultrasound biomicroscopy but not with the clinical ultrasound system. Confirmation with analysis by necropsy and histopathology showed excellent diagnostic capability of ultrasound biomicroscopy for most CHDs. Ventricular septal defect was the most common CHD observed, whereas outflow tract and atrioventricular septal defects were the most prevalent complex CHD. Cardiac/visceral organ situs defects were observed at surprisingly high incidence. The rarest CHD found was hypoplastic left heart syndrome, a phenotype never seen in mice previously., Conclusions: We developed a high-throughput, 2-tier ultrasound phenotyping strategy for efficient recovery of even rare CHD phenotypes, including the first mouse models of hypoplastic left heart syndrome. Our findings support a genetic pathogenesis for a wide spectrum of CHDs and suggest that the disruption of left-right patterning may play an important role in CHD.

Objectives: To determine which method of operative fixation, plate and screw, or intramedullary nails (IMN) fixation is superior for pediatric both bone forearm fractures (BBFF)., Data Sources: PubMed, EMBASE, and Cochrane, from 1980 to 2011, in English., Study Selection: We selected for detailed review all studies with children or adolescents with comparative data (or individual patient data) for BBFF fixed with IMN or open reduction internal fixation with plates and screws. Selected studies also required outcomes of interest including fracture union, complications, functional outcome, cosmesis, and the need for hardware removal., Data Extraction: Data were extracted from each study; publication bias was assessed using funnel plots and Egger statistic. Study quality was assessed using the standardized method described by Zaza et al., Data Synthesis: A DerSimonian and Laird random-effects model was used to assess differences between dichotomous variables. A continuity correction was applied in cases of zero events. A sensitivity analysis was performed with studies that separated out older children and adolescents., Conclusions: All studies identified were observational. IMN and plate and screw constructs are acceptable options in the fixation of pediatric BBFF. The literature fails to demonstrate a difference between IMN and plate and screw constructs. Outcomes were excellent in nearly 9 of 10 patients regardless of fixation strategy. Delayed unions and nonunions were rare and slightly more common in IMN, although the difference was not statistically significant. These results suggest that complication rates are similar, although the type of complication may vary. IMN provides improved cosmesis but, in general, requires a second operation to remove hardware.

There is growing evidence of a positive association between asthma and suicidal ideation and behavior in the general community, although information on this potential association is scarce among older children and adolescents and Puerto Ricans, groups at risk for both conditions. Data came from wave 3 of the Boricua Youth Study, a longitudinal study of youth in the Bronx and San Juan conducted from 2000 to 2004. Logistic regressions for correlated data (Generalized Estimating Equation) were conducted, with asthma predicting suicidal ideation and behavior among participants 11 years or older. After adjustment for survey design; age; sex; poverty; Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, mental disorders; cigarette smoking; and stressful life events, asthma was positively associated with suicidal ideation and behavior among the Puerto Rican older children and adolescents. Public health interventions targeting Puerto Rican older children and adolescents with asthma and future studies investigating potential biological and psychological mechanisms of association are warranted.

Background: Mice are well suited for modeling human congenital heart disease (CHD), given their 4-chamber cardiac anatomy. However, mice with CHD invariably die prenatally/neonatally, causing CHD phenotypes to be missed. Therefore, we investigated the efficacy of noninvasive microcomputed tomography (micro-CT) to screen for CHD in stillborn/fetal mice. These studies were performed using chemically mutagenized mice expected to be enriched for birth defects, including CHD., Methods and Results: Stillborn/fetal mice obtained from the breeding of N-ethyl-N-nitrosourea mutagenized mice were formalin-fixed and stained with iodine, then micro-CT scanned. Those diagnosed with CHD and some CHD-negative pups were necropsied. A subset of these were further analyzed by histopathology to confirm the CHD/no-CHD diagnosis. Micro-CT scanning of 2105 fetal/newborn mice revealed an abundance of ventricular septal defects (n=307). Overall, we observed an accuracy of 89.8% for ventricular septal defect diagnosis. Outflow tract anomalies identified by micro-CT included double outlet right ventricle (n=36), transposition of the great arteries (n=14), and persistent truncus arteriosus (n=3). These were diagnosed with a 97.4% accuracy. Aortic arch anomalies also were readily detected with an overall 99.6% accuracy. This included right aortic arch (n=28) and coarctation/interrupted aortic arch (n=12). Also detected by micro-CT were atrioventricular septal defects (n=22), tricuspid hypoplasia/atresia (n=13), and coronary artery fistulas (n=16). They yielded accuracies of 98.9%, 100%, and 97.8%, respectively., Conclusions: Contrast enhanced micro-CT imaging in neonatal/fetal mice can reliably detect a wide spectrum of CHD. We conclude that micro-CT imaging can be used for routine rapid assessments of structural heart defects in fetal/newborn mice.

Among Latino adults and children, ataques de nervios has been associated with an array of psychiatric disorders. Using data from a probability sample of Puerto Rican children, aged 5 to 13 years (N = 2491), we assessed the lifetime prevalence and psychiatric correlates of ataques in youth residing in the South Bronx, New York and San Juan, Puerto Rico. Baseline site comparisons indicated that between 4% and 5% of children had a lifetime prevalence of ataques (either by child or parent report) and that ataques were associated with greater global impairment and a host of childhood disorders within the previous twelve months. Ataques were also correlated with greater exposure to violence, as well as more stressful life events for the South Bronx sample. After controlling for several covariates, ataques continued to be significantly associated with psychopathology. Ataques are, therefore, a significant correlate of global impairment and childhood psychopathology among Puerto Rican youth.

Background: A consequence of ischemia/reperfusion (IR) is endothelial barrier dysfunction and intravascular volume loss. The purposes of our study are to explore the impact of: 1) cyclic guanosine monophosphate (cGMP) synthesis inhibition, 2) cyclic adenosine monophosphate (cAMP) synthesis inhibition, 3) treatment with endothelin-1, and 4) endothelin-1 (ET-1)-mediated cAMP changes on IR-induced fluid leak. We hypothesize that IR-mediated microvascular fluid leak results from increased cGMP activity and ET-1 decreases IR-induced fluid leak via cAMP., Methods: A micro-cannulation technique was used to determine fluid leak or hydraulic permeability (Lp) in rat mesenteric venules. Lp was measured during IR and after treatment with 1) cGMP synthesis inhibitor (LY83583,10 micromol/L) 2) cAMP synthesis inhibitor (2',5'dideoxyadenosine,10 micromol/L), 3) ET-1 (80 pM), and 4) cAMP synthesis inhibitor plus ET-1 (n=6 in each group; Lp represented as mean+/-standard error of the mean; units 10-cm/sec/cmH2O)., Results: IR resulted in an increase in Lp (Lp=7.07+/-0.20) sevenfold above baseline (1.05+/-0.31) (p

Asthma is a serious and vexing problem for many children and their families. Asthma, like most syndromes, has many symptoms and potential causes and effects. Studies have shown that pediatric asthma is associated with psychiatric disorders, but the specificity and temporality of these relations is not well known. This study examined the associations between any and specific psychiatric disorders and both childhood asthma and other childhood chronic illnesses. The study used the Methods for the Epidemiology of Child and Adolescent Mental Disorders data, a four-site, community-based study of 1,285 pairs of youths and caretakers. Psychiatric disorders were assessed using the Diagnostic Interview Schedule for Children (DISC 2.3). Methods for the Epidemiology of Child and Adolescent Mental Disorders was also used to assess individual characteristics, parental reports of asthma, and other chronic illnesses. Asthma and 'other' chronic illnesses were associated with different psychiatric disorders. In particular, having a history of asthma was associated with having an anxiety disorder, after adjustment for potential confounding, but was not associated with having an affective disorder. Having a chronic illness other than asthma or cancer was associated with having any affective disorder and dysthymia but not anxiety disorder. These results call for more mechanistic research that explores the specific relations between childhood anxiety disorder and asthma and between affective disorder and other pediatric chronic illnesses.

Septic episodes in thermal injuries are usually hallmarked by a series of physiologic parameters that include tachypnea, prolonged paralytic ileus, hyperthermia or hypothermia, altered mental status, thrombocytopenia, leukocytosis or unexplained leukopenia, acidosis, and hyperglycemia. Recent studies with polycystic kidney disease have clearly indicated that the limulus amebocyte lysate (LAL) assays were predictive of fungal infections in this patient population. Because both bacteria and fungi produce lipopolysaccharide that can be identified with the LAL assay, we randomly assayed sequential sera of 45 patients with major thermal injuries for positivity in the LAL assay, with use of the QCL-1000 kit (BioWhittaker, Walkersville, Md). The average burn size of this patient population was 63.43% total body surface area. The average age of the patient was 6.2 years. The sex distribution included 30 males and 15 females. The infectious agents included gram-positive cocci and gram-negative rods, and 14 patients had concomitant fungal infections. Eighty-five percent of the patients tested were positive for endotoxin, with levels ranging from < 0.1 EU/mL to > 1.0 EU/mL. The predominant organism isolated before or on the date the serum was drawn was Pseudomonas aeruginosa (51%), followed by Klebsiella pneumoniae (15%). The remaining 34% were a variety of Enterobacteriaceae. Of the 14 patients who yielded a fungus, 3 had negative LAL assays. Two patients with an elevated LAL grew only Staphylococcus epidermidis in the bloodstream and the wounds. These data clearly indicate that the LAL assay cannot be relied on as the sole predictor of septic episodes; however, it can be an adjunctive test to confirm sepsis when the other parameters have been considered.

Objective: To determine the safety and efficacy of recombinant human growth hormone (rhGH) in the treatment of children who are severely burned., Summary Background Data: During the last decade, we have used recombinant human growth hormone (rhGH; 0.2 mg/kg/day s.q.) to successfully treat 130 children with more than 40% total body surface area (TBSA) burns to enhance wound healing and decrease protein loss. A significant increase in the mortality of adult patients in the intensive care unit who were given rhGH has recently been reported in two large European trials which questions the therapeutic safety of rhGH., Methods: The records of 263 children who were burned were reviewed. Patients receiving either rhGH at 0.2 mg/kg/day subcutaneously as part of a randomized clinical trial (n = 48) or therapeutically (n = 82) were compared with randomized placebo-administered controls (n = 54), contiguous matched controls (n = 48), and matched patients admitted after August 1997, after which no patients were treated with rhGH (n = 31). Morbidity and mortality, which might be altered by rhGH therapy, were considered with specific attention to organ function or failure, infection, hemodynamics, and calcium, phosphorous, and albumin balance., Results: A 2% mortality was observed in both rhGH and saline placebo groups in the controlled studies, with no differences in septic complications, organ dysfunction, or heart rate pressure product identified. In addition, no difference in mortality could be shown for those given rhGH therapeutically versus their controls. No patient deaths were attributed to rhGH in autopsies reviewed by observers blinded to treatment. Hyperglycemic episodes and exogenous insulin requirements were higher among rhGH recipients, whereas exogenous albumin requirements and the development of hypocalcemia was reduced., Conclusions: Data indicate that rhGH used in the treatment of children who were severely burned is safe and efficacious.

Survival after a major thermal burn is precarious and fraught with difficult complications associated with hypermetabolism, gut or respiratory dysfunction, and infection. Clinicians must be cognizant of a new threat to the patient with burn injuries--the emergence of vancomycin-resistant enterococci (VRE). In an analysis of 31 clinical isolates obtained during acute burn hospitalization, an optimal antimicrobial therapy for VRE has been identified. All VRE cultures were inoculated to the MicroScan Gram-Positive Breakpoint Combo Panel #8 (Dade Microscan, Inc, Sacramento, Calif), which speciates the enterococci, provides antimicrobial susceptibility patterns (including vancomycin) and a biotype, and examines streptomycin and gentamicin synergy. Eleven (35.5%) of the 31 isolates were identified as E faecium and 20 (64.5%) as E faecalis. All isolates were susceptible to chloramphenicol and tetracycline, whereas only half were sensitive to gentamicin synergy screen. All other antimicrobials screened against VRE were either ineffective or of limited effect. Our preliminary data supports the initiation of chloramphenicol therapy when a VRE burn wound infection is encountered or suspected.

Children with spina bifida, cerebral palsy, mental retardation, developmental delays, and seizure states are handicapped with sensorimotor deficits, including gait or coordination instability, temperature insensitivity, and mental simplicity. These handicaps make this distinct and unpretentious population more susceptible to lethal burns. A 30-year review was conducted in a pediatric burn center to examine the relationships between pediatric sensorimotor deficit and burn injury. Of the 4874 acute burn admissions, 66 children were identified with preexisting sensorimotor deficits. Data indicate that children with sensorimotor deficit are more prone to burn injury from both their physical impairment and poorly supervised environments. In addition to extended hospitalizations, these children bear significantly higher mortality risks. Had the special supervisions and protection required by such handicapped children been provided, 80% of the burn injuries could have been prevented. Results emphasize that the future of these special children with sensorimotor deficits relies on health care providers playing a greater role in educating parents and caregivers.
