SUMMARYPurpose: To evaluate the presence of metabolic syndrome (MS) in children and adolescents treated with valproate (VPA). Methods: One hundred fourteen patients (54 male and 60 female) were studied. These patients were followed from the beginning of therapy for at least 24 months; at the end of follow-up, 46 patients (40.4%) had a considerable increase in body weight, whereas the other patients (59.6%) remained with the same weight. The MS was defined as having at least three of the following: abdominal obesity, dyslipidemia, glucose intolerance, and hypertension.Results: Forty-six patients developed obesity; 20 (43.5%) of 46 patients developed MS. Abnormal glucose homeostasis was identified in 45% of patients. High total serum cholesterol concentrations were noted in 10 (50%), high serum triglyceride concentrations in 7 (35%), and low high-density lipoprotein (HDL) in 15 (75%) of the 20 subjects with MS. However, there were no significant differences in the features of MS between boys and girls with MS. Conclusions: Patients who gain weight during VPA therapy can develop MS with a possible risk of cardiovascular disease.

A retrospective multicentre study was performed to analyse psychogenic non-epileptic seizures (PNES) in prepubertal and pubertal patients with idiopathic epilepsy and to determine whether have different clinical characteristics. In this study, we reviewed 36 patients from six neurological referral centres: Department of Pediatrics, Chieti (3 patients); Department of Child Neuropsychiatry, Naples (9 patients); Department of Child Neuropsychiatry, Bologna (8 patients); Department of Neuroscience, Tor Vergata University, Rome (3 patients); Department of Pediatrics, La Sapienza University, Rome (5 patients); and Department of Pediatrics, Siena (8 patients). The population was divided according to Tanner'stages into 14 prepubertal (group I) and 22 pubertal (group II) patients. The two groups were compared on several variables examining the differences between them. The most frequent clinical manifestations in group I were unresponsive events, whereas in group II, motor events were exhibited more significantly. Mood disorders, including major depression, appeared more frequently in pubertal group, but this did not reach a significant difference. Among the psychosocial stressors, fear of rejection and need for attention were the predominant types in the prepubertal patients. The findings of this study reveal some similarities and differences between prepubertal and pubertal patients, which might help to identify predictive factors in patients affected by idiopathic epilepsy who can develop PNES.

Since 1990 eight new antiepileptic drugs (AEDs) have been developed. Among these new drugs, Topiramate (TPM) is one of the latest AEDs available for treating drug resistant partial epilepsy both in adults and in children. The mechanisms underlying TPM antiepileptic activity are still incompletely understood. However, TPM, a sulfamate-substituted derivative of the naturally occurring monosaccharide D-fructose, has a different structure from other known AEDs. The antiepileptic activity of TPM in animal models of partial and generalized tonic-clonic seizures has been shown to be more effective as compared to other AEDs. Proposed mechanisms of action include reduction of epileptiform discharges through a voltage-dependent block of Na(+) channels, enhancement of the activity of gamma-aminobutyrate at some subtypes of gamma-aminobutyrate receptors, and antagonism of non- N-methyl-D-aspartate (NMDA) glutamate receptors. The pharmacokinetic profile of TPM, which is characterized by its rapid and almost complete absorption after oral administration, linear pharmacokinetics, minimal protein binding and predominantly renal excretion, makes the drug a good option for the treatment. TPM was found to be effective and well tolerated in many studies conducted in adults and pediatric patients suffering from epilepsy. This review, summarising the main studies in this field, provides an overview of the current knowledge about the relevant pharmacological and clinical information on the efficacy and tolerability of TPM.

Objectives: It was the aim of this study to evaluate the recurrence and progression at 1, 3 and 5 years in patients with non-muscle-invasive bladder cancer (NMIBC) who underwent a transurethral resection of bladder cancer following intravesical adjuvant chemotherapy or immunotherapy if indicated and to compare them with the European Organization for Research and Treatment of Cancer (EORTC) risk tables. Patients and Methods: Between 2002 and 2011, a total of 259 patients with NMIBC were treated with transurethral resection of bladder cancer. According to the clinical and pathological factors used by the EORTC scoring system, the patients were divided into four groups, and for each group, the probabilities of recurrence and progression were calculated. Results: The recurrence and progression rates of NMIBC of our patients were similar to those in the EORTC risk score system. Moreover, in our sample group, we found a minimally significant reduction in the recurrence rate in the intermediate- and high-risk groups. Conclusion: From the results obtained, we considered it essential to introduce the use of EORTC risk tables into our clinical practice to determine the recurrence and progression of NMIBC.

Antiepileptic drugs (AED) are a heterogeneous group of compounds widely used in both adults and children. These drugs are related to various adverse effects involving several organs and endocrinological and metabolic functions. In particular, relevant effects on thyroid function have been described. Subclinical hypothyroidism and alterations in thyroid hormone serum levels are reported in the literature; phenytoin, valproate and carbamazepine, in particular, seem to be involved in these alterations. The aim of this review is to analyse critically the principal alterations in thyroid function caused by AED therapy.
