Selected AbstractsCourse and outcome of childhood epilepsy: A 15-year follow-up of the Dutch Study of Epilepsy in ChildhoodEPILEPSIA, Issue 7 2010Ada Geerts Summary Purpose:, To study the course and outcome of childhood-onset epilepsy during 15-year follow-up (FU). Methods:, We extended FU in 413 of 494 children with new-onset epilepsy recruited in a previously described prospective hospital-based study by questionnaire. Results:, Mean FU was 14.8 years (range 11.6,17.5 years). Five-year terminal remission (TR) was reached by 71% of the cohort. Course during FU was favorable in 50%, improving in 29%, and poor or deteriorating in 16%. Mean duration of seizure activity was 6.0 years (range 0,21.5 years), strongly depending on etiology and epilepsy type. Duration was <1 year in 25% of the cohort and exceeded 12 years in another 25%. Antiepileptic drugs (AEDs) were used by 86% during a mean of 7.4 years: one-third had their last seizure within 1 year of treatment, and one-third continued treatment at the end, although some had a 5-year TR. At last contact, 9% of the cohort was intractable. In multivariate analysis, predictors were nonidiopathic etiology, febrile seizures, no 3-month remission, and early intractability. Eighteen patients died; 17 had remote symptomatic etiology. Standardized mortality ratio for remote symptomatic etiology was 31.6 [95% confidence interval (CI) 18.4,50.6], versus 0.8 [95% CI 0.02,4.2] for idiopathic/cryptogenic etiology. Discussion:, In most children with newly diagnosed epilepsy, the long-term prognosis of epilepsy is favorable, and in particular, patients with idiopathic etiology will eventually reach remission. In contrast, epilepsy remains active in ,30% and becomes intractable in ,10%. AEDs probably do not influence epilepsy course; they merely suppress seizures. Mortality is significantly higher only in those with remote symptomatic etiology. [source] Location of Mutation in the KCNQ1 and Phenotypic Presentation of Long QT SyndromeJOURNAL OF CARDIOVASCULAR ELECTROPHYSIOLOGY, Issue 11 2003Ph.D., WOJCIECH ZAREBA M.D. Introduction: Recent data showed that long QT syndrome (LQTS) patients with mutations in the pore region of the HERG (LQT2) gene have significantly higher risk of cardiac events than subjects with mutations in the non-pore region. The aim of this study was to determine whether there is an association between the location of mutations in the KCNQ1 gene and cardiac events in LQT1 patients. Methods and Results: The study population consisted of 294 LQT1 patients with KCNQ1 gene mutations. Demographic, clinical, and follow-up information was compared among subjects with different locations of KCNQ1 mutations defined as pre-pore region including N-terminus (1,278), pore region (279,354), and post-pore region including C-terminus (>354). Cardiac events observed during follow-up from birth until age of last contact or age 40 years were defined as syncope, cardiac arrest, or sudden death. There were 164 (56%) LQT1 patients with pre-pore mutations, 101 (34%) with pore mutations, and 29 (10%) with post-pore mutations. QTc duration did not differ significantly among the three subgroups (mean QTc = 494, 487, and 501 ms, respectively). There was no significant difference between groups with regard to the risk of cardiac events by age 40 years. Conclusion: There are no significant differences in clinical presentation, ECG parameters, and cardiac events among LQT1 patients with different locations of KCNQ1 mutations. These findings indicate that factors other than location of mutation influence clinical phenotype in patients with LQT1 mutations.

Methods:, Data collection was based on a questionnaire administered to the reference psychiatrists. Results:, Over a period of 12 months, 166 catchment area residents attempted suicide. Sixty-six (40%) had contacted the mental health department in the previous two years and completed data were obtained on 63. Twenty-nine (46%) suffered from mood, 26 (41%) from personality and 11 (18%) from schizophrenic disorders. Thirty-four attempts occurred within one year of psychiatric ward discharge, mostly in the first quarter. The reference psychiatrists reported that, at the last evaluation, 38 of 63 patients (60%) presented no change in clinical conditions, and 41 of 63 (68%) were considered at no immediate risk of suicide. Most of the attempted suicides in question (45, 72%) were judged to be unpreventable. In the two logistic regression analyses carried out, no independent variables were able to statistically significantly explain the variance in judged suicidal risk or the preventability of the index attempted suicide. Conclusions:, According to the psychiatrists' descriptions of their last contact with the patients, most attempted suicides have not been preceded by a change in clinical conditions. Moreover, psychiatrists, irrespective of their age and gender, and of patient diagnosis, frequently judged the attempts to have been unpreventable. [source] Remission of epilepsy after two drug failures in children: A prospective study,ANNALS OF NEUROLOGY, Issue 5 2009Anne T. Berg PhD Objective Determine the probability of a more than 1-year remission after failure of a second drug in children prospectively followed from initial diagnosis of epilepsy and then from time of second drug failure. Identify prognostic factors for remission after second drug failure. Methods Of 613 children, 128 did not respond favorably to 2 drugs, had a trial of at least a third drug (median, 3), and were followed for more than 1 year (median, 10.1 years) since second drug failure. Product limit and proportional hazards techniques were used to analyze predictors of any 1-year remission (Rem1) and 1- and 3-year remission at last contact (Rem1/3-LC). Results Seventy-three patients (57%) had a remission. Repeated remissions and relapses were common. Only 48 (37.5%) achieved Rem1-LC and 28 (23%) Rem3-LC. Idiopathic epilepsy (Rem1: rate ratio [RR], 3.64, p < 0.0001; Rem1-LC: RR, 2.57, p = 0.008) and seizure frequency (Rem1: RR, 0.76, p = 0.003; Rem1-LC: RR, 0.82, p = 0.04 per increase in category) were the most robust predictors. Symptomatic cause was the only correlate of Rem3-LC. Remission before second drug failure did not predict remission after second drug failure. Interpretation Remission after second drug failure is common but often temporary. Children who have not responded to two appropriate drugs should be carefully evaluated to maximize therapy and possibly considered for more aggressive treatments.

Spiess Study Type , Prognosis (retrospective cohort) Level of Evidence 2b OBJECTIVE To gather a pooled database from six tertiary-care referral centres using salvage cryotherapy (SC) for locally recurrent prostate cancer, and develop a pretreatment nomogram allowing a prediction of the probability of biochemical failure after SC, based on pretreatment clinical variables. PATIENTS AND METHODS We retrospectively analysed 797 men treated at six tertiary-care referral centres with SC for locally recurrent disease after primary radiotherapy with curative intent. The median duration of follow-up from the time of SC to the date of last contact was 3.4 years. The primary study endpoint was biochemical failure, defined as a serum prostate-specific antigen (PSA) level after SC of >0.5 ng/mL. RESULTS Overall, the rate of biochemical failure was 66% with a median of 3.4 years of follow-up. A logistic regression model was used to predict biochemical failure. Covariates included serum PSA level at diagnosis, initial clinical T stage, and initial biopsy Gleason score. On the basis of these results, a pretreatment nomogram was developed which can be used to help select patients best suited for SC. Our pretreatment nomogram was internally validated using 500 bootstrap samples, with the concordance index of the model being 0.70. CONCLUSION A pretreatment nomogram based on several diagnostic variables (serum PSA level at diagnosis, biopsy Gleason grade, and initial clinical T stage) was developed and might allow the selection of ideal candidates for SC.
