The postprandial glucose response to some varieties of commercially available gluten-free pasta: a comparison between healthy and celiac subjects.

The objective of the present paper is to evaluate the post-prandial response to some varieties of gluten free (GF) pasta that are commonly consumed in Italy. The glycaemic responses were compared with a glucose standard in healthy subjects and gluten-free diet celiac subjects. Subjects were served portions of the test foods and a standard food (glucose), on separate occasions, each containing 50 g available carbohydrates. Capillary blood glucose was measured from finger-prick samples in fasted subjects and at 15, 30, 45, 60, 90 and 120 minutes after the consumption of each test food. For each type of pasta, the glycaemic index (GI) was calculated by expressing the incremental area under the blood glucose curve as a percentage of each subject's average incremental area under the blood glucose curve (AUC) for the standard food. Gluten free pasta exhibited a range of GI values from 46 to 66. The glycaemic load (GL) and glycaemic profile (GP) were also calculated. A higher GI value was observed in pasta containing rice flour as the main ingredient. Lower values were observed in pasta obtained using corn or a mixture of corn and rice flour as the main ingredients. The results were confirmed in celiac subjects. The information presented in this paper may be useful in helping celiac people to select low-GI pasta.

[Choroidal metastasis from clinically regressed prostate adenocarcinoma: imaging of a rare case]. / Métastase choroïdienne d'un adénocarcinome de la prostate: iconographie d'un cas rare.

INTRODUCTION: Choroidal metastases are often the revealing feature of malignant diseases. We report a rare case of prostatic adenocarcinoma metastases at the choroids, diagnosed and followed by fluorescein angiography (FA), indocyanine-green angiography (ICGA), and optical coherence tomography (OCT-3 Stratus). OBSERVATION: A 54-year-old man was referred to our department for decreased vision in his left eye lasting for 1 month. On ophthalmic evaluation, best corrected visual acuity (BCVA) was 20/20 in his right eye and 20/63 in his left eye. Biomicroscopic examination of the anterior segments did not reveal anything abnormal in either eye. Funduscopic examination revealed two amelanotic choroidal masses in both his right and left eyes, located at the posterior pole and at the periphery. The systemic workup, including hematologic analysis and total-body computed tomography (CT), revealed elevated serum prostate-specific antigen (PSA) and alkaline phosphatase, extensive abnormalities of the axial skeleton, and nodular pulmonary shadows; therefore, prostatic adenocarcinoma was suspected. Needle biopsies (prostatic and pulmonary) confirmed adenocarcinoma of the prostate, with metastatic disease. We decided to submit the patient to intermittent total androgen blockade alone, without adjunctive radiotherapy. The patient responded well to intermittent total androgen blockade with oral bicalutamide and triptorelin injection alone, as documented on fundus pictures, ultrasonography, OCT, FA, and ICGA. DISCUSSION: Prostatic carcinoma should be considered in any male patient with a choroidal mass suspected of being a metastasis. In our patient, FA, ICGA, and OCT clearly documented the complete regression of choroidal metastasis from prostatic carcinoma. Fluorescein angiography, indocyanine-green angiography, and optical coherence tomography are useful tools in the diagnosis and follow-up of prostatic adenocarcinoma metastatic to the choroid.
