Hepatoblastoma in adults is a rare malignancy that presents in the epithelial or mixed epithelial-mesenchymal variants. We report two cases, the former representing the epithelial and the latter the mixed type. A 21 year-old woman with epigastric pain had abdominal ultrasound and CT scans showing a large hepatic mass. A right trisegmentectomy was performed. The first and second recurrences were treated by resection. The third recurrence was treated by hepatic transarterial chemo-embolization, systemic chemotherapy and 19 percutaneous alcohol injections. A careful follow up by abdominal ultrasound and CT scans was able to detect the recurrence at an early stage. The patient is well at 151 months. A 39 year-old man with epigastric pain and dyspepsia had upper-GI series and abdominal CT scan showing a left hepatic mass involving the stomach. Liver resection and Billroth II hemigastrectomy were performed. A recurrence involving the left hepatic lobe, the spleen and the remaining stomach occurred 15 months later and the patient died from multi organ failure. Surgery is the treatment of choice of hepatoblastoma in adults. Recurrences can also be treated aggressively by surgical resections if no extrahepatic organs are involved. Other therapeutic modalities can be attempted whenever surgery is not possible.

Transdermal nicotine delivery systems are widely used in smoking cessation. The purpose of this study was to determine whether common symptoms of pyrosis and dyspepsia associated with these patches are related to gastroesophageal reflux or esophageal dysmotility. Twenty-seven paid volunteer cigarette smokers (> 15 cigarettes/day) without symptomatic gastroesophageal reflux disease participated in this single-blinded, placebo-controlled study. Twenty subjects completed the study. Subjects underwent three sequential 24-h intraesophageal pH/motor studies (Synectics model T32342084, Shore View, MN). The pH/motility probe was positioned 5 cm above the manometrically determined LES. A placebo patch was applied for the first 24-h study and a 15-mg nicotine patch (Nicotrol) was applied for the initial 16 h (removed for remaining 8 h) of the second 24-h period. A 21-mg nicotine patch (Nicoderm) was applied for another 24-h study period. All subjects consumed an identical, defined diet documented by meal receipts, and refrained from smoking and tobacco use throughout the study periods (CO breath test confirmation). The Wilcoxon, paired t-test, exact McNemar statistical methods were used. The results showed that there were no significant differences in reflux symptoms (pyrosis, chest pain, nausea, dysphagia), supine gastroesophageal reflux (number of episodes, duration, or cumulative acid exposure), or the total number of reflux episodes between placebo and nicotine patch treatment periods. The number of post-prandial upright acid reflux episodes (p = 004) and number of upright acid reflux episodes lasting more than 5 min (p = 0.007) were statistically higher with the placebo patch compared to the active nicotine patches. No differences in intraesophageal pH or motility indices were noted between the two transdermal nicotine patches (Nicotrol, Nicoderm). It was concluded that dyspeptic symptoms in subjects utilizing transdermal nicotine patches are not related to gastroesophageal reflux or to esophageal motor abnormalities.

A 21-day, open-label, multisite, dose escalation study comprising three demographic groups (children, adolescents, and adults) was performed to determine the pharmacokinetics and tolerability of orally administered buspirone. Thirteen children and 12 adolescents with anxiety disorder and 14 normal healthy adults were escalated from 5 to 30 mg buspirone bid over the 3-week study. Pharmacokinetic analysis revealed that buspirone was rapidly absorbed in all study groups, reaching peak levels at about 1 hour after administration. Peak plasma buspirone concentrations (Cmax) were highest in children and lowest in adults at all three dose levels (7.5, 15, 30 mg bid). However, 1-pyrimidinylpiperazine (1-PP), the primary metabolite of buspirone, exhibited a different plasma concentration-time profile; Cmax was significantly higher in children than in either adolescents or adults at all concentrations. In addition, TAUC0-T for 1-PP was significantly higher in the children cohort relative to adolescents and adults. Buspirone was generally safe and well tolerated at doses up to 30 mg bid in adolescents and adults and most of the children. The most frequently reported adverse events in children and adolescents were lightheadedness (68%), headache (48%), and dyspepsia (20%); 2 children withdrewfrom the study at the higher doses (15 mg and 30 mg bid) due to adverse effects. In adults, the most common adverse effect was somnolence (21.4%); lightheadedness, nausea, vomiting, and diarrhea were also reported, although these were mild in intensity.
