Background: Phenylketonuria (PKU) is one of the most common inborn errors of amino acids metabolism. It is an autosomal recessive disease that is caused by mutations in phenylalanine hydroxylase (PAH) gene. In the North Africa and Eastern Mediterranean region, E280K missense mutation and c.1055del.G frameshift mutation in PAH gene are one of the most common pathogenic mutations seen in PKU patients. Materials and Methods: In this study, we developed molecular protocols for rapid screening of the PKU patients for these two mutations. These protocols are based on hydrolysis probe real-time polymerase chain reaction technique using allele-specific probes labeled with 6-carboxyfluorescein (FAM) for wild-type (WT) and hexachloro-6-carboxyfluorescein (HEX) for mutant genotypes and Black Hole Quencher 1 as a quencher and high-resolution melting analysis using EvaGreen saturating dye. Results: There was complete accordance between the developed protocols in differentiating genotypes and they proved to be rapid, sensitive, and efficient for the detection and differentiation between WT, mutant, and heterozygous genotypes of the E280K and c.1055del.G mutations. Conclusions: These protocols allow easy molecular screening of the mutations studied among the families of affected people, especially for premarital screening. arabic 27 English 170

Despite the relative abundance of sunny weather, surprisingly, there is increasing evidence that vitamin D deficiency is extremely prevalent in females of reproductive age in Middle East countries. There is also increasing interest in the non-classical roles of vitamin in health and disease including its relation to incidence of gestational diabetes, its impact on glycaemic control in diabetes mellitus, and its association with some complications of pregnancy like preeclampsia. The objective of this study was to estimate the prevalence of Vitamin D deficiency in pregnant diabetic patients in west Libya and analyse potential links to socioeconomic and cultural factors. This is a cross sectional observational study. Random plasma was collected form expected mothers attending the Antenatal Diabetes Clinic at Tripoli’s Main Maternity Hospital. Demographics and socioeconomic and cultural factors were recorded at the same time. Samples were analysed for vitamin D level and biochemical screening panel. Vitamin D level was obtained from 160 patients (mean age 35 years). Over all 95 % of the study population had vitamin D levels below normal (defined as vitamin D level of < 20 ng/mL). Results were subcategorised into severe deficiency ( 30 ng/ml, only 1.3%, 2 patients). All patients were taking daily vitamin D Supplements at a dose of 400 IU as per hospital policy. Vitamin D deficiency is extremely prevalent in pregnant diabetic patients in Libya. There is no clear association with socioeconomic risk factors like employment, type of accommodation or geographic distribution. However, most of the study population had life style characterized by minimal exposure to direct sun arabic 11 English 70

Evidence based medicine, clinical reasoning, self-directed critical thinking and problem solving approach are mandatory in order to acquire better retained and usable knowledge in a clinical context through student-centered teaching, and team interpersonal skills promotion. Adoption of new and high standards methods of teaching such as 3D models [24,25], along with updated responsive teaching materials are mandatory and represent pre-requirements for accredited medical schools
