Exposure to Ochratoxin A from Rice Consumption in Lebanon and United Arab Emirates: A Comparative Study.

Our study aims to evaluate the ochratoxin A (OTA) in rice marketed in Lebanon and the United Arab Emirates (UAE), and to determine the exposure to OTA from rice consumption. All brands available in the market were collected twice (total number of collected samples: 105 and 127 in Lebanon and the UAE, respectively). Using ELISA, the OTA in 56 (53%) samples in Lebanon and 73 (58%) samples in the UAE were above the limit of quantification (0.8 µg/kg). The average concentrations of the positive samples ± standard deviations were 1.29 ± 0.32 and 1.40 ± 0.42 µg/kg in Lebanon and the UAE, respectively. Only one sample (1%) in Lebanon had a level at the borderline of the European Union (EU) limit, and two samples (1.6%) in the UAE had a level above the EU limit (5 µg/kg). The OTA in brown rice was higher than in white and parboiled rice for both countries, yet the difference was not significant. The packing season, packing country, and country of origin did not have any significant effects. The presence of a food safety certification resulted in lower OTA in the rice, but the difference was significant (p = 0.04) in the UAE only. Long grains had higher OTA than short grains, yet the difference was only significant in Lebanon (p = 0.046). The exposures were calculated as 1.27 ng/kg body weight/day in Lebanon and 1.42 ng/kg body weight/day in the UAE, and no health risk was observed for both the neoplastic and non-neoplastic effects.

Gallbladder-associated symptomatic hepatic choristoma: Should you resect?

INTRODUCTION: Hepatic choristomas or ectopic livers are uncommon, and occur due to a failure of embryological liver development. They pose a risk of carcinogenesis, with transformation to hepatocellular carcinoma (HCC) being described in the literature (Arakawa et al., 1999). It is often a silent clinical finding that can occur anywhere in the body and is usually diagnosed incidentally during abdominal surgical procedures or autopsies (Eiserth et al., 1940). We present the case of a patient with a symptomatic ectopic liver that was detected preoperatively, and removed laparoscopically with the gallbladder. PRESENTATION OF CASE: A 73-year-old lady was referred to our unit for a gallbladder tumor on ultrasound which was done for biliary colic. Tumor markers were normal. Computed tomography (CT) scan showed an enhanced soft tissue lesion measuring about 3×1.5cm interposed between the gallbladder and liver. Laparoscopic exploration revealed a bean-shaped hepatic choristoma attached to the liver on the medial wall of the gallbladder. The lesion was removed by en-bloc resection during laparoscopic cholecystectomy and extracted carefully in an endobag. Histopathological examination confirmed the absence of carcinogenesis. DISCUSSION AND CONCLUSION: Hepatic choristomas (HC) are a rare entity, usually identified during abdominal surgeries. It had been reported in several studies with different presentations. Awareness of this unexpected finding and familiarity of its potential complications and carcinogenesis will improve care delivery when encountered. Surgical treatment should be considered when the choristoma is not attached to the liver, in light of its potential transformation into HCC.
