ABSTRACT
Valproic acid (VPA) is commonly prescribed medication for epilepsy, migraine and bipolar disorder. Although the common adverse effect associated with VPA are typically benign, less common adverse effect can occur; these include hepatotixicity, teratogenicity and acute pancreatitis (AP). VPA-induced pancreatitis does not depend on valproic acid serum level and may occur anytime after onset of therapy. Re-challenge with VPA is dangerous and should be avoided. The diagnosis of VPA-induced pancreatitis seems to be underestimated because of difficulties in determining the causative agent and the need for a retrospective re-evaluation of the causative factor. More of idiopathic pancreatitis should be a drug-induced pancreatitis. We report four cases of VPA-induced AP found in a group of 52 cases of AP in children come to our attention from January 2008 to December 2012. The aim of these reports is to point out our experience about clinical presentation, diagnosis, management, outcome in children with VPA-induced AP and review of literature.

AIM: The aim of this retrospective study was to report our experience about characteristics of clinical presentation, etiologies, diagnosis and medical or surgical treatment of pediatric cholelitiasis. METHODS: Twenty-four children, ranging from 7 to 17 years of age (14 females and 10 males), with diagnosis of cholelitiasis were studied from 2008 through 2011. Exclusion criteria included: active infection, cholangitis, severe anemia or thrombocytopenia in cases with hemolytic diseases. Diagnosis was performed with abdominal ultrasonography-scanner (US). Furthermore, complete peripheral blood examination was performed to all patients. Follow-up was conducted by clinical and US and/or CT supports between 6 and 24 months. RESULTS: Laparoscopic cholecystectomy was performed in 16 patients, conservative management in 10. No cases of majority morbility or death rate were found. RMN-colangiography was conducted in 2 cases with cholestasis elevated index: no stone were found in common bile duct. During follow-up evaluation, 2 patients began sympotimatic and were undergone to cholecystectomy. "Wait and see" management was performed in all asymptomatic cases. In only 2 cases ursodeoxycholic acid (UDCA) was administrated. CONCLUSION: Laparoscopic cholecystectomy is a "gold standard" also for a treatment of cholelitiasis in childhood; it is an efficacy and safe treatment also for pediatric gallstones. Medical therapy with UDCA lead not to dissolution of gallstones but it had a positive effect on the symptoms.

AIM: The aim of this study was to report our experience about clinical presentation and management in children with mild and sever acute pancreatitis (PA). METHODS: At the onset of clinical manifestations the following laboratory and instrumental tests were performed to all patients: abdominal ultrasonography, measurement of blood amylase and lipase and PCR; preventive antibiotic therapy, gabexate mesylate and proton pump inhibitors were also administrated to all patients. During the follow-up CT and dosage amylase and lipase in blood were performed. RESULTS: Results summarize data of 52 patients with suspected diagnosis of acute pancreatitis admitted to our hospital within 24 h of symptoms (from January 2008 to December 2011). Age ranged between 4-18 years, and the study included 30 females and 22 males. According to Santorini Consensus Conference, 40 patients were defined having a mild and 12 a severe pancreatitis. All patients with mild PA underwent a medical and/or surgical treatment (endoscopic retrograde cholangiopancreatography, laparoscopic cholecystectomy); there were 2 fatalities between patients with severe PA and 2 cases of pancreatic pseudocyst treated with guided CT drainage and therapy with octreotide. All patients had abdominal pain but the location, severity and duration of pain were extremely variable. Blood dosage of amylase was altered in 83% of cases and of lipase in 100%. Ultrasonography showed abnormalities in 89% of the patients and TC showed alterations of pancreatic parenchyma in 100% of the cases when performed at 48 h. CONCLUSION: In absence of randomized controlled studies, systematic review or guidelines for diagnosis and management of PA in pediatric age we used our experiences on adult patients, aware of this approach limitation.

In utero exposure to antiepileptic drugs (AEDs) may affect neurodevelopment causing postnatal cognitive and behavioral alterations. Phenytoin and phenobarbital may lead to motor and learning dysfunctions in the pre-exposed children. These disorders may reflect the interference of these AEDs with the development of hippocampal and cerebellar neurons, as suggested by animal studies. Exposure to valproic acid may result in inhibition of neural stem cell proliferation and/or immature neuron migration in the cerebral cortex with consequent increased risk of neurodevelopmental impairment, such as autistic spectrum disorders. A central issue in the prevention of AED-mediated developmental effects is the identification of drugs that should be avoided in women of child-bearing potential and during pregnancy. The aim of this review is to explore the possible link between AEDs and neurodevelopmental dysfunctions both in human and in animal studies. The possible mechanisms underlying this association are also discussed.
