RESUMEN

The objective of this article is to summarise the current knowledge regarding the prevalence of six rheumatological conditions in indigenous Australians - rheumatoid arthritis (RA), osteoarthritis (OA), osteoporosis (OSP), systemic lupus erythematosus (SLE), gout and musculoskeletal (MSK) pain. Online medical literature databases were searched for 'indigenous', 'Aboriginal' and 'Torres Strait Islander', as well as the names of the six conditions. Other included search terms were 'crystal', 'urate', 'arthritis' and 'arthropathy'. No limitations were placed on publication data or language. Forty-five articles examining the prevalence of the six conditions were identified. Based on the published literature, SLE appears to have a higher prevalence, while RA appears to have a lower prevalence in indigenous Australians compared to the non-indigenous community. MSK pain is prevalent, has a significant impact on indigenous people and is perceived as an important area of need. There is a paucity of data regarding these conditions in indigenous Australians. This may be impacted by the uncertainty of case ascertainment by self-report, differences in disease phenotypes and prevalence between the metropolitan compared to the rural or remote indigenous population, and difficulty with access to healthcare. Further studies in conjunction with local indigenous communities are needed to accurately determine the burden of rheumatological disease in the indigenous population. This will assist with resource and workforce planning to deliver culturally appropriate interventions. Strategies for future clinical work and research include the development and dissemination of culturally safe rheumatology resources, rheumatology training of Aboriginal Health Workers and wider integration of rheumatology clinics into community-controlled Aboriginal Health Services.

RESUMEN

BACKGROUND: Gout is a common chronic inflammatory disorder due to monosodium urate deposition, which results in severe inflammatory arthritis. It is particularly common in those of Maori or Pacific Islander heritage. There is a significant number of this at-risk ethnic group in western Sydney. AIMS: To determine the healthcare burden of gout in Western Sydney. METHODS: We characterised patients managed in the emergency departments (EDs) of the four Western Sydney Local Health District (WSLHD) hospitals and those admitted for gout as the primary or secondary diagnosis from 1 January 2017 to 31 December 2018. RESULTS: There were 472 patients managed in ED on 552 occasions at a direct cost to the LHD of A$367 835. Those of Maori or Pacific Islander ethnicity comprised 25.2% (n = 119/472), while half (n = 39/80) of those managed in ED for gout on two or more occasions were of Maori or Pacific Islander ethnicity. Overall, 310 patients were admitted with gout as the principal diagnosis on 413 occasions at a cost of A$1.73 million. Seventy-five (24.2%) of the 310 patients were of Maori or Pacific Islander heritage. A total of 584 WSLHD inpatients had gout as a secondary diagnosis. This was associated with 714 admissions. CONCLUSIONS: The disproportionately large healthcare burden of gout in Western Sydney from the relatively small Maori and Pacific Islander population needs attention. Urgent culturally appropriate interventions to address gout are required to address this inequality.

RESUMEN

BACKGROUND: For hospitals participating in bundled payment programs, unplanned readmissions after surgery are often termed "bundle busters." The aim of this study was to develop the framework for a prospective model to predict 90-day unplanned readmissions after elective primary total hip arthroplasty (THA) at a macroscopic hospital-based level. METHODS: A national, all-payer, inpatient claims and cost accounting database was used. A mixed-effect logistic regression model measuring the association of unplanned 90-day readmissions with a number of patient-level and hospital-level characteristics was constructed. RESULTS: Using 427,809 unique inpatient THA encounters, 77 significant risk factors across 5 domains (ie, comorbidities, demographics, surgical history, active medications, and intraoperative factors) were identified. The highest frequency domain was comorbidities (64/100) with malignancies (odds ratio [OR] 2.26), disorders of the respiratory system (OR 1.75), epilepsy (OR 1.5), and psychotic disorders (OR 1.5), being the most predictive. Other notable risk factors identified by the model were the use of opioid analgesics (OR 7.3), Medicaid coverage (OR 1.8), antidepressants (OR 1.6), and blood-related medications (OR 1.6). The model produced an area under the curve of 0.715. CONCLUSION: We developed a novel model to predict unplanned 90-day readmissions after elective primary THA. Fifteen percent of the risk factors are potentially modifiable such as use of tranexamic acid, spinal anesthesia, and opioid medications. Given the complexity of the factors involved, hospital systems with vested interest should consider incorporating some of the findings from this study in the form of electronic medical records predictive analytics tools to offer clinicians with real-time actionable data.

RESUMEN

Background: Androgen deprivation therapy (ADT) is a key component of therapy for patients with high-risk prostate carcinoma, but it may be deleterious for bone health. We sought to determine the frequency of dual energy x-ray absorptiometry (DXA) scanning in patients commencing adjuvant ADT for treatment of high-risk prostate cancer at a large integrated regional cancer centre. Material and methods: The electronic medical records (EMR) of all patients with high-risk prostate carcinoma commenced on adjuvant ADT between January 1, 2016 and December 31, 2017 at the Mid-North Coast Cancer Institute, Coffs Harbour, Australia were reviewed. Patients commenced on neoadjuvant ADT and long-term suppressive ADT for metastatic disease were excluded. The following data were obtained: socio-demographic information, prostate cancer data, ADT details and DXA results. Results: 188 men (mean age ± SD, 75.4 ± 7 years) were commenced on adjuvant ADT for a total duration (mean ± SD) of 23.4 ± 7 months. Most (n = 155/188, 82%) were commenced on leuprorelin acetate. While only 26/188 (14%) had a DXA scan performed prior to ADT, another 133 (71%) had a DXA scan at a median of 20 days (interquartile range 7-98), later. Of the 159 men with DXA readings, 76 (48%) were osteopaenic and 38 (24%) were osteoporotic by DXA criteria. Conclusion: A high level (85%) of DXA scanning in men commencing ADT for prostate cancer can be achieved at a regional centre. The high prevalence (72%) of low bone mass in our unselected cohort underscores the importance of routine DXA scanning to guide bone health management during ADT.

RESUMEN

INTRODUCTION: Among children with infantile spasms (ISs), those with trisomy 21 (T21) and those with normal development at onset and no identifiable etiology (previously referred to as "idiopathic") are expected to have relatively favorable outcomes. The study objective is to determine if differences exist in treatment response, relapse, and subsequent epilepsy between these two groups when vigabatrin is used as first-line treatment. METHODS: In this retrospective study, patients were classified into the following groups and clinical features were compared: T21 (n = 24) and IS with normal development at onset and no identified etiology (n = 40; control group). RESULTS: There was no significant difference in the age of IS onset, sex distribution, or treatment lag between the groups. The T21 compared to the control group required a higher mean number of anti-seizure therapies (3.6 vs. 1.9, p < 0.001), had more relapses [10 (42%) vs. 4 (10%), p < 0.005)], and had higher risk of subsequent epilepsy [11 (46%) vs. 8 (20%), p < 0.003]. Relapses were often delayed in the T21 group, with a mean of 8 months after IS cessation. CONCLUSION: Our results differ from most studies using steroids as first-line treatment where the groups were shown to have similar treatment response and T21 patients had a low risk of relapse and subsequent epilepsy. Therefore, our results suggest that vigabatrin as first-line treatment in T21 with IS may be less favorable than steroids.

RESUMEN

OBJECTIVE: Benign epilepsy of childhood with central temporal spikes (BECTS) and absence epilepsy are common epilepsy syndromes in children with similar age of onset and favorable prognosis. However, the co-existence of the electrocardiogram (EEG) findings of rolandic spike and 3 Hz generalized spike-wave (GSW) discharges is extremely rare, with few cases reported in the literature. Our objective was to characterize the EEG findings of these syndromes in children in our center and review the electro-clinical features. METHODS: All EEGs at BC Children's Hospital are entered in a database, which include EEG findings and clinical data. Patients with both centro-temporal spikes and 3 Hz GSW discharges were identified from the database and clinical data were reviewed. RESULTS: Among the 43,061 patients in the database from 1992 to 2017, 1426 with isolated rolandic discharges and 528 patients with isolated 3 Hz GSW discharges were identified, and 20 (0.05%) patients had both findings: 3/20 had BECTS, and subsequently developed childhood absence epilepsy and 17/20 had no seizures characteristic for BECTS. At follow-up, 17 (85%) were seizure-free, 1 (5%) had rare, and 2 (10%) had frequent seizures. CONCLUSIONS: This is the largest reported group of patients to our knowledge with the co-existence of rolandic and 3 Hz GSW discharges on EEGs in one institution, not drug-induced. As the presence of both findings is extremely rare, distinct pathophysiological mechanisms are likely. The majority had excellent seizure control at follow-up, similar to what would be expected for each type of epilepsy alone.


OBJECTIF: L'épilepsie bénigne de l'enfance à pointes centro-temporales (ou épilepsie rolandique bénigne [ERB]) et l'absence épileptique sont des syndromes épileptiques communs chez des enfants dont le pronostic est favorable et dont l'apparition des premiers symptômes s'est produite à un âge similaire. Cependant, la coexistence, lors d'EEG, de résultats montrant des décharges rolandiques et des décharges à pointes-ondes continues de 3 Hz demeure extrêmement rare, peu de cas ayant été signalés dans la littérature scientifique. Notre objectif a donc consisté à décrire les résultats d'EEG liés à ces syndromes dans le cas d'enfants fréquentant notre établissement et à examiner leurs caractéristiques électro-cliniques. MÉTHODES: En plus de certaines données cliniques, tous les résultats d'EEG réalisés au BC Children's Hospital sont saisis dans une base de données. Tant les jeunes patients donnant à voir des décharges à pointes centro-temporales que ceux atteints de décharges à pointes-ondes continues de 3 Hz ont été identifiés à partir de cette base de données. Leurs données cliniques ont été ensuite passées en revue. RÉSULTATS: Sur un total de 43 061 jeunes patients présents dans la base de données de 1992 à 2017, nous en avons identifié 1426 avec des décharges rolandiques isolées et 528 avec des décharges isolées à pointes-ondes de 3 Hz. À noter que seulement vingt d'entre eux, soit 0,05 %, étaient concernés par ces deux types de décharge. À cet égard, 3 sur 20 étaient atteints d'ERB et ont développé ultérieurement un syndrome d'absence épileptique; chez les 17 autres, aucune convulsion caractéristique de l'ERB n'a été observée. Lors d'un suivi, 17 (85 %) d'entre eux n'avaient plus de crises convulsives tandis que 1 (5 %) avait exceptionnellement des crises et 2 (10 %), des crises fréquentes. CONCLUSIONS: À notre connaissance, il s'agit là du plus vaste groupe déclaré de patients donnant à voir, lors d'EGG menés au sein d'un seul établissement, une coexistence entre des décharges rolandiques et des décharges à pointes-ondes de 3 Hz, et ce, sans qu'elles n'aient été causées par des médicaments. Considérant que la présence de ces deux phénomènes est particulièrement inhabituelle, le rôle de divers mécanismes pathophysiologiques est fort probable. Fait à souligner, la majorité de ces patients ont pu montrer, au moment de leur suivi, une excellente maîtrise de leurs crises convulsives, maîtrise semblable à celle à laquelle on pourrait s'attendre pour chaque type d'épilepsie pris individuellement.

RESUMEN

PURPOSE OF REVIEW: Conventional synthetic disease modifying anti-rheumatic drugs (csDMARDs) have been used in the treatment of inflammatory arthritis (IA) for many years. More recently, biologic (bDMARDs) and targeted synthetic (tsDMARDs) DMARDs have further improved treatment. Due to increased patient longevity and effective oncology treatment, rheumatologists often encounter patients with IA and previous malignancy. The immunosuppressive effect of DMARDs causes concern regarding impaired tumour surveillance with a potential increased risk of malignancy. We reviewed the literature regarding the risk of malignancy in patients on cs-/b-/tsDMARDS and sought to provide practical advice regarding use of these drugs in patients with previous malignancy. RECENT FINDINGS: Data from randomised controlled trials is limited as patients with pre-existing malignancy are often excluded. Reassuringly, an increasing range of "real world" data from various national b/tsDMARD registries has not provided a convincing signal that these drugs increase tumour recurrence. Nevertheless, awareness of, and adherence to, national screening guidelines for malignancy is important. Given the improvement in quality of life achieved with these novel and well-tolerated therapeutic agents, the benefit/risk profile remains overwhelmingly favourable in most patients.

RESUMEN

Providing health services with the greatest possible value to patients and society given the constraints imposed by patient characteristics, health care system characteristics, budgets, and so forth relies heavily on the design of structures and processes. Such problems are complex and require a rigorous and systematic approach to identify the best solution. Constrained optimization is a set of methods designed to identify efficiently and systematically the best solution (the optimal solution) to a problem characterized by a number of potential solutions in the presence of identified constraints. This report identifies 1) key concepts and the main steps in building an optimization model; 2) the types of problems for which optimal solutions can be determined in real-world health applications; and 3) the appropriate optimization methods for these problems. We first present a simple graphical model based on the treatment of "regular" and "severe" patients, which maximizes the overall health benefit subject to time and budget constraints. We then relate it back to how optimization is relevant in health services research for addressing present day challenges. We also explain how these mathematical optimization methods relate to simulation methods, to standard health economic analysis techniques, and to the emergent fields of analytics and machine learning.

RESUMEN

Pulmonary hypertension (PH) is a clinical condition characterised by raised pulmonary artery pressure, which results in increased right ventricular afterload and dyspnoea. This is accompanied by reduced exercise capacity, quality of life and, eventually, death. An increasing range of targeted medications has transformed the treatment of pulmonary arterial hypertension, a specific type of PH. Supervised exercise training is recommended as part of a multifaceted management plan for PH. However, many questions remain regarding how exercise training improves exercise capacity and quality of life. The optimal exercise regimen (frequency, timing, duration and intensity) also remains unclear. This review provides an update on the pathophysiology of exercise impairment in PH, suggests mechanisms by which exercise may improve symptoms and function and offers evidence-based recommendations regarding the frequency and intensity of an exercise programme for patients with PH.

RESUMEN

Autoimmune inflammatory rheumatic diseases (AIIRD), such as rheumatoid arthritis, psoriatic arthritis and ankylosing spondylitis are often complicated by infection, which results in significant morbidity and mortality. The increased risk of infection is probably due to a combination of immunosuppressive effects of the AIIRD, comorbidities and the use of immunosuppressive conventional synthetic disease-modifying anti-rheumatic drugs (DMARDs) and more recently, targeted synthetic DMARDs and biologic DMARDs that block specific pro-inflammatory enzymes, cytokines or cell types. The use of these various DMARDs has revolutionised the treatment of AIIRD. This has led to a marked improvement in quality of life for AIIRD patients, who often now travel for prolonged periods. Many infections are preventable with vaccination. However, as protective immune responses induced by vaccination may be impaired by immunosuppression, where possible, vaccination may need to be performed prior to initiation of immunosuppression. Vaccination status should also be reviewed when planning overseas travel. Limited data regarding vaccine efficacy in patients with AIIRD make prescriptive guidelines difficult. However, a vaccination history should be part of the initial work-up in all AIIRD patients. Those caring for AIIRD patients should regularly consider vaccination to prevent infection within the practicalities of routine clinical practice.

RESUMEN

OBJECTIVE: To report the initial two and a half years' experience of one of the first Fracture Liaison Services in regional Australia. DESIGN: Case study. SETTING: Hospital Clinic, mid-north coast NSW. PARTICIPANTS: Patients aged ≥50 years with a fragility fracture identified at Coffs Harbour Health Campus July 2012 to December 2014. INTERVENTION: Patients were identified by a Fracture Liaison Coordinator (FLC) and seen in Fracture Prevention Clinic (FPC) by a rheumatologist. Patients discharged from FPC were contacted via telephone on one occasion 12 months later. MAIN OUTCOME MEASURES: Number/characteristics of patients seen in or declining an appointment in FPC, type of bone protective therapy commenced and patient adherence with this. RESULTS: An appointment in FPC was offered to 222 patients but declined by 56 patients. One hundred and sixty-six patients were seen in FPC, of whom 40% (n = 66/166) had a prevalent fragility fracture but only 12% (n = 8/66) were on bone protective therapy. Eighty-two percent (n = 136/166) commenced bone protective therapy. Of the 55 patients discharged from FPC with long enough follow-up to allow contact at 12 months, 60% (n = 33/55) required bone health advice during the follow-up telephone call at 12 months. Of the 31 patients who commenced bone protective therapy, 65% (n = 20/31) said they were adherent with medication. CONCLUSIONS: A FLC, committed clinician and supportive hospital environment were all that was required for an effective Fracture Liaison Service in a regional hospital. The number of patients who declined an appointment suggested the implications of a fragility fracture were often not appreciated.

RESUMEN

Survivors of preterm birth are at high risk of pervasive cognitive and learning impairments, suggesting disrupted early brain development. The limits of viability for preterm birth encompass the third trimester of pregnancy, a "precritical period" of activity-dependent development characterized by the onset of spontaneous and evoked patterned electrical activity that drives neuronal maturation and formation of cortical circuits. Reduced background activity on electroencephalogram (EEG) is a sensitive marker of brain injury in human preterm infants that predicts poor neurodevelopmental outcome. We studied a rodent model of very early hypoxic-ischemic brain injury to investigate effects of injury on both general background and specific patterns of cortical activity measured with EEG. EEG background activity is depressed transiently after moderate hypoxia-ischemia with associated loss of spindle bursts. Depressed activity, in turn, is associated with delayed expression of glutamate receptor subunits and transporters. Cortical pyramidal neurons show reduced dendrite development and spine formation. Complementing previous observations in this model of impaired visual cortical plasticity, we find reduced somatosensory whisker barrel plasticity. Finally, EEG recordings from human premature newborns with brain injury demonstrate similar depressed background activity and loss of bursts in the spindle frequency band. Together, these findings suggest that abnormal development after early brain injury may result in part from disruption of specific forms of brain activity necessary for activity-dependent circuit development. SIGNIFICANCE STATEMENT: Preterm birth and term birth asphyxia result in brain injury from inadequate oxygen delivery and constitute a major and growing worldwide health problem. Poor outcomes are noted in a majority of very premature (<25 weeks gestation) newborns, resulting in death or life-long morbidity with motor, sensory, learning, behavioral, and language disabilities that limit academic achievement and well-being. Limited progress has been made to develop therapies that improve neurologic outcomes. The overall objective of this study is to understand the effect of early brain injury on activity-dependent brain development and cortical plasticity to develop new treatments that will optimize repair and recovery after brain injury.

RESUMEN

Rheumatoid arthritis (RA) is an autoimmune inflammatory disease which results in extensive articular and extra-articular morbidity and increased mortality from cardiovascular disease. Despite an increasing range of non-biological and biological disease-modifying agents, poor patient adherence with medication is a significant barrier to effective control of the inflammation associated with RA. This review seeks to identify factors that affect patient adherence with medication, examine the effectiveness of interventions to address this issue and offer practical suggestions to improve medication adherence. The impact of health literacy on medication adherence and the novel role of musculoskeletal ultrasound as an educational intervention will also be discussed.

RESUMEN

Health care delivery systems are inherently complex, consisting of multiple tiers of interdependent subsystems and processes that are adaptive to changes in the environment and behave in a nonlinear fashion. Traditional health technology assessment and modeling methods often neglect the wider health system impacts that can be critical for achieving desired health system goals and are often of limited usefulness when applied to complex health systems. Researchers and health care decision makers can either underestimate or fail to consider the interactions among the people, processes, technology, and facility designs. Health care delivery system interventions need to incorporate the dynamics and complexities of the health care system context in which the intervention is delivered. This report provides an overview of common dynamic simulation modeling methods and examples of health care system interventions in which such methods could be useful. Three dynamic simulation modeling methods are presented to evaluate system interventions for health care delivery: system dynamics, discrete event simulation, and agent-based modeling. In contrast to conventional evaluations, a dynamic systems approach incorporates the complexity of the system and anticipates the upstream and downstream consequences of changes in complex health care delivery systems. This report assists researchers and decision makers in deciding whether these simulation methods are appropriate to address specific health system problems through an eight-point checklist referred to as the SIMULATE (System, Interactions, Multilevel, Understanding, Loops, Agents, Time, Emergence) tool. It is a primer for researchers and decision makers working in health care delivery and implementation sciences who face complex challenges in delivering effective and efficient care that can be addressed with system interventions. On reviewing this report, the readers should be able to identify whether these simulation modeling methods are appropriate to answer the problem they are addressing and to recognize the differences of these methods from other modeling approaches used typically in health technology assessment applications.

RESUMEN

In a previous report, the ISPOR Task Force on Dynamic Simulation Modeling Applications in Health Care Delivery Research Emerging Good Practices introduced the fundamentals of dynamic simulation modeling and identified the types of health care delivery problems for which dynamic simulation modeling can be used more effectively than other modeling methods. The hierarchical relationship between the health care delivery system, providers, patients, and other stakeholders exhibits a level of complexity that ought to be captured using dynamic simulation modeling methods. As a tool to help researchers decide whether dynamic simulation modeling is an appropriate method for modeling the effects of an intervention on a health care system, we presented the System, Interactions, Multilevel, Understanding, Loops, Agents, Time, Emergence (SIMULATE) checklist consisting of eight elements. This report builds on the previous work, systematically comparing each of the three most commonly used dynamic simulation modeling methods-system dynamics, discrete-event simulation, and agent-based modeling. We review criteria for selecting the most suitable method depending on 1) the purpose-type of problem and research questions being investigated, 2) the object-scope of the model, and 3) the method to model the object to achieve the purpose. Finally, we provide guidance for emerging good practices for dynamic simulation modeling in the health sector, covering all aspects, from the engagement of decision makers in the model design through model maintenance and upkeep. We conclude by providing some recommendations about the application of these methods to add value to informed decision making, with an emphasis on stakeholder engagement, starting with the problem definition. Finally, we identify areas in which further methodological development will likely occur given the growing "volume, velocity and variety" and availability of "big data" to provide empirical evidence and techniques such as machine learning for parameter estimation in dynamic simulation models. Upon reviewing this report in addition to using the SIMULATE checklist, the readers should be able to identify whether dynamic simulation modeling methods are appropriate to address the problem at hand and to recognize the differences of these methods from those of other, more traditional modeling approaches such as Markov models and decision trees. This report provides an overview of these modeling methods and examples of health care system problems in which such methods have been useful. The primary aim of the report was to aid decisions as to whether these simulation methods are appropriate to address specific health systems problems. The report directs readers to other resources for further education on these individual modeling methods for system interventions in the emerging field of health care delivery science and implementation.

RESUMEN

Bisphosphonates such as alendronate, risedronate and zoledronate have revolutionised the treatment for osteoporosis and Paget's disease. These drugs reduce fracture risk and probably mortality in patients with osteoporosis. However, they have a long in vivo half-life following cessation and may be associated with delayed dental healing and even the devastating complication of osteonecrosis of the jaw (ONJ). Extensive media attention highlighting this issue has caused much concern among patients and healthcare professionals.

RESUMEN

OBJECTIVES: To improve osteoporosis (OSP) management following minimal trauma fracture (MTF) with few additional resources. DESIGN: Population intervention with serial cross-sectional analysis. SETTING: Regional setting involving primary care, base hospital and private hospital. PARTICIPANTS: Patients with MTF. INTERVENTION: A 'Fracture Card' prompting OSP management was provided to all patients post-MTF. Patients were encouraged to attend their general practitioner (GP) with this to discuss bone health issues. The 2-year intervention was supported by a public health education campaign. MAIN OUTCOME MEASURES: Number of (i) serum 25-OH vitamin D assays, (ii) dual-energy X-ray absorptiometry (DXA) scans, and (iii) new Pharmaceutical Benefits Scheme (PBS)-subsidised prescriptions for bone protective therapy (bisphosphonates, raloxifene, strontium, teriparatide, denosumab). RESULTS: The number of serum 25-OH vitamin D assays ordered in Coffs Harbour increased from 329 ± 15 per month (July 2009-June 2010) to 568 ± 21 (July 2010-June 2012; P < 0.001). The number of DXA scans performed per month increased from 192 ± 14 (July 2009-June 2010) to 296 ± 12 (July 2010-June 2012; P < 0.001). There was no difference in the number of new PBS-subsidised prescriptions for bone protective therapy in the Coffs statistical subdivision over that time (176 ± 3.8 per month, July 2009-June 2010 versus 180 ± 3.5, July 2010-June 2012, P > 0.05). CONCLUSIONS: The intervention was associated with an increased number of 25-OH vitamin D assays and DXA scans but not with more prescriptions for bone protective therapy. This suggests that a public health education campaign and provision of a 'prompt' for GPs was only partially successful at improving OSP management post-MTF. This has driven establishment of a Fracture Liaison Service.

RESUMEN

Introduction: Absence seizures occur in various epilepsy syndromes, including childhood and juvenile absence epilepsy and juvenile myoclonic epilepsy. When children present with absence seizures at ages when syndromes overlap, initial syndrome designation is not always possible, making early prognostication challenging. For these children, the study objective is to determine clinical and initial electroencephalograph (EEG) findings to predict the development of generalized tonic-clonic seizures, which is a factor that affects outcome. Methods: Children with new-onset absence seizures between 8 and 11 years of age with at least 5 years of follow-up data were studied through the review of medical records and initial EEG tracings. Results: Ninety-eight patients were included in the study. The median age of absence seizure onset was 9 years (interquartile range [IQR] = 8.00, 10.00) and follow-up was 15 years (IQR = 13.00, 18.00). Forty-six percent developed generalized tonic-clonic seizures and 20% developed myoclonic seizures. On multiple regression analysis, a history of myoclonic seizures, anxiety, as well as bifrontal slowing and mild background slowing on initial EEG (P < .05) were associated with generalized tonic-clonic seizures. Although not statistically significant, a shorter duration of shortest EEG burst on baseline EEG was also associated with generalized tonic-clonic seizures. Conclusion: On initial EEG, bifrontal and background slowing and myoclonic seizures and anxiety are associated with developing generalized tonic-clonic seizures, which is of prognostic significance when early syndrome designation is difficult.
