Abstract
About half of patients with Graves’ disease develop an orbitopathy related to an inflammatory expansion of the periorbital adipose tissue and muscles. We used a targeted metabolomic approach measuring 188 metabolites by mass spectrometry to compare the metabolic composition of tears in patients with active (n = 21) versus inactive (n = 24) thyroid-associated orbitopathy. Among the 44 metabolites accurately measured, 8 showed a significant alteration of their concentrations between the two groups. Two short-chain acylcarnitines, propionylcarnitine and butyrylcarnitine, and spermine showed increased concentrations in the tears of patients with active orbitopathy, whereas ornithine, glycine, serine, citrulline and histidine showed decreased concentrations in this group. In addition, the ratio putrescine/ornithine, representing the activity of ornithine decarboxylase, was significantly increased in patients with active compared to inactive orbitopathy (p = 0.0011, fold change 3.75). The specificity of this candidate biomarker was maintained when compared to a control group with unclassified dry eye disease. Our results suggest that the stimulation of ornithine decarboxylase by TSH receptor autoantibodies in orbital fibroblasts could lead to increased synthesis of spermine, through the increased activity of ornithine decarboxylase, that may contribute to periorbital expansion in Graves’ ophthalmopathy.

Abstract
OBJECTIVE To study the adolescent student's knowledge and its sources about AIDS, and its mode of spread in Islamabad. SETTING One boys and two girls schools in Islamabad. METHODS A cross-sectional survey was conducted, using an anonymous, self-administered, brief Urdu questionnaire which was distributed among 100 boys and 182 girls. RESULTS The response rate was 100% and the average age of respondents was 14.6 years in boys and 12 years in girls. Most respondents knew about AIDS and reported television as their main source of knowledge. Most respondents also correctly believed that AIDS patient can pass on the disease to others, however, they had erroneous beliefs about its mode of transmission. CONCLUSION This study testifies to the effectiveness of the successful television based health education campaign regarding AIDS in the adolescent boys and girls, in Islamabad.

Abstract
The aim of this was to evaluate the pattern of care for diabetic patients in Alexandria as a model from a developing country. It is a cross-sectional multi-centric. One thousand diabetic patients who had diabetes for no less than one year were randomly selected from 14 out-patient clinics and diabetic centres. Results showed that monitoring of the glycaemic state was based, almost entirely upon fasting blood glucose levels, with only a small minority (4%) having HbA measurements. During the previous 12 months, an electrocardiogram had not been performed in 26% of the subjects studies and the fundus was not examined in 38%. Twenty nine percent did not receive neurological examination, and feet were not inspected in 24%. Testing for albuminuria, serum creatinine, blood cholesterol, and triglycerides was performed only in 34%, 37%, 36% and 32% respectively. Patient's habits in seeking care revealed that 78% regularly attended the medical centre for follow up, 64% followed dietetic instructions, and 89% were compliant with prescribed therapy. Only 8% did self examination of blood glucose and 26% checked glucose in urine by themselves. Generally, the pattern of care provided for health insured diabetic patients is better than that received by non-health-insured cases. It is concluded that in Egypt the quality of diabetes care differs in many aspects from the recommended standards and that structural as well as organisational improvements are urgently needed, particularly to guarantee adequate care to non-health insured patients.

Abstract
Experience with the yeast recombinant hepatitis B vaccine Engerix-B now exceeds 10 years. We reviewed published studies on this vaccine. These show the vaccine to be safe, causing mostly only minor local symptoms and to be highly immunogenic both in monitored clinical trials and under field conditions. Engerix-B consistently elicits high geometric mean antibody titres and a high protective efficacy has been established in three groups at high-risk of hepatitis B infection, homosexual men, institutionalised mentally handicapped subjects and neonates of chronic carrier mothers. The profile of the recombinant hepatitis B vaccine in certain high-risk groups and immuno compromised people is discussed. Finally we present updated post marketing surveillance data based on 496 million distributed doses of vaccine.
