RESUMO
BACKGROUND: The Healthy Lifestyle-Diet Index (HLD-index), previously developed to assess the degree of adherence to dietary and lifestyle guidelines for primary schoolchildren, was revised according to updated recommendations. Τhe association of the revised HLD-index (R-HLD-index) with obesity and iron deficiency (ID) was also examined. METHODS: A representative sample of 2660 primary schoolchildren from Greece (9-13 years old) participating in the 'Healthy Growth Study' was examined. Twelve components related to dietary and lifestyle patterns were used to develop the R-HLD-index. Scores from 0 up to 4 were assigned to each one of these components, giving a total score ranging from 0 to 48. The associations between the R-HLD-index, obesity and ID were examined via logistic regression analysis. RESULTS: The total score of the R-HLD-index calculated for each one of the study participants was found to range between 2 and 32 units, with higher scores being indicative of a healthier lifestyle and better diet quality. After adjusting for potential confounders, logistic regression analysis showed that an increase in the R-HLD-index score by one unit was associated with 6% lower odds for obesity. However, no significant association was observed between the R-HLD-index score and ID. CONCLUSIONS: The R-HLD-index may be a useful tool for public health policy makers and healthcare professionals when assessing diet quality and lifestyle patterns of primary schoolchildren. Identification of children with lower scores in the R-HLD-index and its individual components could guide tailored made interventions targeting specific children and behaviors.

Idiopathic inflammatory orbital myosites represent 10% of the orbital pseudotumors and 8% of the orbital pathologic processes in children. They are rarely described although they raise real diagnostic problems. The authors report the case of a 10-year old little girl who presented sudden proptosis. The clinical and radiological work up and the therapeutic test with corticosteroids were in favor of an inflammatory orbital myositis. The authors remind the clinical, radiological, and therapeutical aspects of this entity that remains very unfrequent in children and needs to be differenciated from rhabdomyosarcoma.

The effect of thyroid hormones and chemically related compounds, on the activity of UDP-glucuronosyltransferases (EC 2.4.1.17) and cytochrome P-450-dependent monooxygenases in rat liver microsomes was investigated. The animals were thyroidectomized and treated with different doses of the drugs for 3 weeks. Opposite effects were observed depending on the isoenzyme of UDP-glucuronosyltransferase considered. While 3,3',5-triiodo-L-thyronine, 3,3',5-triiodothyroacetic acid, 3,3',5-triiodothyropropionic acid, isopropyldiiodothyronine and L- and D-thyroxine strongly increased 4-nitrophenol glucuronidation in a dose-dependent fashion, they decreased markedly bilirubin glucuronidation. However, the activity toward nopol, a monoterpenoid alcohol, was not significantly changed regardless of which compound or dose was used. Variation of UDP-glucuronosyltransferase observed with 4-nitrophenol and bilirubin was related to the thyromimetic effect of the drugs estimated from the increase in alpha-glycerophosphate dehydrogenase. Thyronine and 3,5-diiodo-L-tyrosine, which did not enhance this activity, also failed to affect glucuronidation. Variations in UDP-glucuronosyltransferase activity were more likely due to changes in protein expression rather than changes in enzyme latency, since lipid organization of the microsomal membrane, as estimated from the mean anisotropy of 1,6-diphenyl-1,3,5-hexatriene by fluorescence polarization was not significantly modified by the drug administration. Although some of the drugs could significantly decrease the triacylglycerol and cholesterol contents in plasma, all failed to affect lauric acid hydroxylation. The activities of catalase, palmitoyl-CoA dehydrogenase (CN- insensitive) and carnitine acetyltransferase in the fraction enriched in peroxisomes were also not significantly affected by treatment with the thyroid hormone LT3. In contrast, the activity of 7-ethoxycoumarine O-deethylase was increased by large doses of thyronine and by 3,3',5-triiodothyropropionic acid. The concentration of total cytochrome P-450 was decreased in a dose-dependent fashion by all the compounds used, except thyronine. Finally, significant correlations were observed between glucuronidation of bilirubin and 4-nitrophenol and the content in cytochrome P-450. This suggests a possible coordinate regulation of the two processes, which depends on the physicochemical characteristics of the thyroid hormones and related compounds.

Severe restrictive disorders of ocular motility are rarely described in high myopia. Their cause is still unknown. Several theories have been suggested: structural changes in the ocular muscles, sixth-nerve palsy or an elongation of the ocular globe. We report the case of a 44 years old man with high myopia of the left eye and disturbed ocular motility. Medical imaging techniques (echography, CT, MRI) allowed us to objectify the cause of ocular motility problem.

Ocular manifestations of rheumatoid arthritis are mainly dry eye syndrome, scleritis, and keratitis. The occurrence of corneal ulceration in the course of this disease is a rare complication but can lead to ocular perforation. We report the case of a woman followed for rheumatoid arthritis who presented a bilateral sterile paracentral ulcer that responded well to medical treatment.

Isolated cilioretinal artery occlusion is a rarely reported initial manifestation of polycythemia vera. In this study, we reported a case of a 65-year-old man with polycythemia vera with cilioretinal artery occlusion as an initial manifestation.
RESUMO
The authors report a case of orbital cellulitis complicating bacteremia on central catheter infection. A 51-year-old man, with a history of diabetes and end-stage renal disease, was admitted for left exophthalmos with inflammatory chemosis, fever, and worsening of his general state. The CT scan showed exophthalmos with thickening of soft tissues and infiltration of the ocular fat without collection or sinus impairment. Orbital cellulitis was diagnosed. The etiological investigations showed Staphylococcus aureus bacteremia on femoral catheter infection. Progression was favorable with antibiotics and nursing care. The authors discuss the compromised prognosis of this disease and the need for rapid diagnosis and prompt therapeutic management.

INTRODUCTION: Tuberculosis is an endemic disease responsible for death and morbidity in developing countries. OBSERVATION: A 50-year-old man with no medical history was admitted to the emergency department for meningism associated with fever and confusion. The ophthalmic exam showed a decline in left visual acuity, reduced to light perception, VIth nerve left oculomotor paralysis, ocular fundus demonstrating a yellow tumor located on the posterior segment, measuring 1.5-2mm, papillomatous and prominent in the vitreous cavity. Fluorescein angiography showed a peritumoral choroiditis area, miliary tubercles of the choroid, and sectorial papillomatous edema. Color retinography unmasked inflamed posterior vitreous areas. Echography demonstrated a 4- to 5-mm oval hyperechogeneous and calcified tumor along with hyperechogeneous vitreous areas. Lumbar puncture showed lymphocytic meningitis associated with hyponatremia. The CT scan and MRI demonstrated optic neuritis. The antibiotic therapy was initiated and the outcome was favorable. CONCLUSION: This case report shows the importance of systematic ocular fundus in the presence of systemic tuberculosis and outlines the assessment of color retinography to unmask vitreous lesions. It shows the importance of radiological imaging in the semiological study of orbital and cerebral lesions.
