Wheat allergy is one of the commonest food allergies in childhood and it typically presents with IgE mediated reactions, including anaphylaxis. Seizures are not typically reported to be a direct manifestation of anaphylaxis, though it can occur secondary to hypoxia following significant haemodynamic compromise. We describe a case of a previously well infant, who presented with anaphylactic shock to wheat and responded well to the initial management, but subsequently developed a cluster of brief generalised tonic clonic seizures without any ongoing haemodynamic instability. The tryptase level that was performed at 4–5 hours post reaction was raised at 49.1 µg/L. Skin prick test to wheat, wheat specific IgE, the omega-5 gliadin IgE were positive. Extensive work-up was performed to look for an underlying cause of seizures and all returned negative. To our knowledge, this is the first case report describing an unusual presentation of multiple seizures in a young infant, in association with an anaphylactic episode. In the absence of any other seizure provoking factor and underlying cause, we believe the association is more likely causative than coincidental.

Renal angiomyolipomas are benign neoplasms composed of varying amounts of adipose tissue, smooth muscles and blood vessels. They typically contain macroscopic fat, which is seen as negative attenuation on computed tomography. Calcification and scarring is rarely seen in renal angiomyolipomas. We report the case of a 40-year-old man who was found to have a renal angiomyolipoma with a central stellate scar and focal calcification. The lesion was initially misdiagnosed as a calyceal calculus.

INTRODUCTIONAdvanced hepatocellular carcinoma (HCC) has a dismal prognosis and is notoriously chemo-resistant. We conducted a Phase II prospective study to evaluate the activity and tolerability of gemcitabine and cisplatin in chemo-naïve advanced hepatocellular carcinoma. The trial considered a "no further interest" response rate of 10% and a target response rate of 30%. Utilising a Simon's minimax two-stage design with a type I error of 0.05 and power of 80%, 25 subjects would be required. Fifteen patients would be needed in stage 1 and if fewer than 2 responses were observed, the trial would be stopped and lack of efficacy claimed.

MATERIALS AND METHODSPatients with advanced HCC, diagnosed based on histology or by World Health Organization (WHO) criteria, were administered gemcitabine 1000 mg/m2 and cisplatin 25 mg/m2 on day 1 and day 8 of a 21-day schedule. Assessment of response based on computer tomography was performed after every 2 cycles of chemotherapy.

RESULTSThe trial was stopped early due to a lack of efficacy. A total of 15 patients were accrued. Twelve patients were hepatitis B positive and the other 3 patients were negative for both hepatitis B and C. Only 1 patient had a history of prior heavy alcohol use. Two patients had Child C liver cirrhosis, 5 patients had Child B cirrhosis, and the remaining 8 patients had Child A cirrhosis. This regime was well tolerated and there was only 1 patient who experienced grade IV toxicities. Only 5 of 15 patients experienced grade III toxicities (nausea and emesis, 1 patient; anemia, 1 patient; thrombocytopenia, 1 patient; and neutropaenia, 2 patients). Only 1 patient experienced a partial response to the combination of gemcitabine and cisplatin. A further 3 patients experienced stable disease and 11 patients progressed on chemotherapy. The median time to progression was 6 weeks. The progression-free curve showed a sharp descent in the initial part of the study, suggesting that many patients had disease progression after enrollment. The median overall survival was 18 weeks.

CONCLUSIONThe progression-free survival and overall survival in our study were extremely short. Based on the results of our phase 2 study, we are unable to recommend further studies utilising gemcitabine and cisplatin combination in patients with advanced HCC.
