Bulgular: 791 çocuktan (421 erkek, 370 kız, ortalama yaş 6.5) alınan örnekler test edildi. Tüm çocuklar hayatlarının ilk iki yılında 4 doz tam hücreli boğmaca aşısı ile aşılanmıştı. Yakın zamanda gerçekleşen ve gerçekleşmeyen boğmaca enfeksiyonu sıklığı sırasıyla% 4.8 ve% 2.5 idi. Çocukların% 76.1’i tespit edilemeyecek düzeyde IgG’ye sahipti. Sonuç: Çalışma boğmaca enfeksiyonun okula başlayan çocuklar arasında sık olarak geçirildiğini göstermiştir. Bu artış, okula başlama yaşındaki çocukların% 76.1’inde serumda boğmacaya karşı antikor düzeyinin tespit edilemeyecek düzeyde olmasının dolaylı bir sonucu olması ile açıklanmıştır. arabic 26 English 62

Measles, Mumps ,and rubella (MMR) are serious diseases that can lead potentially to disability and death. The study aimed to determine seroprevalence rates of antibody levels against MMR among Libyan children at school entry. This was a cross sectional study undertaken in Tripoli, from August to September 2016. Children of school-entry age (> 5 to ≤ 7 years) were randomly recruited at vaccination centers. Sera were tested for antibodies againstMMR. Data analyzed by SPSS program version 20. Out of 546 children, 290 were males. IgG antibodies against measles, mumps, and rubella were positive in 513 (94%), 436 (80%), 538 (98.5%) children, respectively. Seropositivity rates in Libyan children at school entry is protective and this is similar in so many other studies. This indicates that MMR vaccine program is effective in strengthening herd immunity in the Libyan community. arabic 19 English 111

Alkaline phosphatase (ALP) enzyme level, which is routinely measured at clinical laboratories, increases in end-stage renal disease (ESRD) and hepatitis patients. This study investigated the difference in ALP level among ESRD and hepatitis patients. ALP level was measured in sera of patients suffering from ESRD, HCV and HBV infections, as well as patients suffering from comorbidity of these diseases, then the obtained values of ALP level were statistically compared to a control group. The results of three-Way ANOVA revealed that the mean of ALP level increased significantly (P-value< 0.05) in all types of diseases compared to the control group, with the highest increase in case of ESRD patients infected with Hepatitis B and C. Also, it was found that the interaction of group-gender significantly (P-value< 0.05) altered ALP level in patients suffering from HCV or HBV infections, while the interaction of group-age, gender-age, group-gender-age were found not to significantly alter it. In conclusion, ESRD patients with HBV/HCV coinfection may have a higher risk of liver-related morbidity and mortality than ESRD or HBV or HCV patients. arabic 25 English 103

Factor V Leiden G1691A (FVL) and Factor II prothrombin G20210A (PGM) mutations are the leading causes of thrombophilia. In this study, we have investigated the prevalence of the FVL G1691A and PGM G20210A single nucleotide polymorphisms (SNPs) among Libyan deep vein thrombosis (DVT) and myocardial infarction (MI) patients. SNP genotyping was performed using high-resolution melt analysis (HRM) and DNA sequencing. Biochemical parameters conducted on 112 males and 93 females showed no significant difference in means between the control group and the deep vein thrombosis and myocardial infarction groups. For Factor V Leiden, 40 samples were genotyped. Of the 40 samples, 6 (15.0%) of them were heterozygous and no one was homozygous. As for Factor II SNP, 59 samples were genotyped and only 2 (3.3%) were heterozygous. All the heterozygous samples showed 100% concordance between the HRM-PCR and DNA sequence analysis. Our study showed, for the first time, that both the FVL and PGM mutations are present among Libyan DVT and MI patients and that the FVL mutation is significantly associated with DVT but not with MI. However, our results do not support the association of PGM G20210A mutation with DVT or MI. arabic 18 English 117

Fungi are a huge source of unexplored bioactive compounds. Owing to their biological activities, several fungi have shown commercial application in the health industry. Tuber aestivum Vittad. is one such edible fungi with an immense scope for practical biological applications. In the present study, the anti-angiogenic activity of petroleum ether and ethanol extracts of T. aestivum was investigated using the chick chorioallantoic membrane assay and compared to the positive controls silibinin and lenalidomide. Both the extracts showed a dose-dependent anti-angiogenic response. The extracts were also assessed for their anti-inflammatory potential by lipoxygenase-inhibition assay. The IC50 values for LOX inhibition assay, computed by the Boltzmann plot, were 368.5, 147.3 and 40.2 μg/mL, for the petroleum ether extract, ethanol extract, and the positive control ascorbic acid, respectively. The ethanol extract of T. aestivum showed superior anti-angiogenic and anti-inflammatory activity than the petroleum ether extract. Compositional investigation of the extracts by GC–MS revealed the presence of various bioactive compounds. The compounds were correlated to their anti-angiogenic and antiinflammatory activity based on a meticulous literature search. arabic 25 English 145

Angiogenesis is a complex physiological process that cannot be treated with single agent therapy. Several edible fungi have been known to encompass bioactive compounds, and are promising sources of multi-component drugs. One such widely consumed edible fungi is Cantharellus cibarius, which has been explored for its biological activities. The present study focused on assessing the anti-angiogenic activity of petroleum ether and ethanol extracts of C. cibarius using chick chorioallantoic membrane (CAM) assay. Both the extracts showed a dose-dependent response which was compared with the anti-angiogenic activity of the positive controls silibinin, and lenalidomide. The extracts were also studied for their lipoxygenase (LOX) inhibitory potential and compared to ascorbic acid as the positive control. The IC50 values of the petroleum ether extract, ethanol extract, and ascorbic acid for LOX inhibition assay were 135.4, 113.1, and 41.5 mg/mL, respectively. Although both the extracts showed similar responses in CAM assay, ethanol extract proved to be more potent in LOX inhibition assay. Finally, the extracts were investigated for their chemical composition using GC-MS. A correlation between LOX inhibition and anti-angiogenic potential was established at the molecular level. A meticulous literature search was carried out to correlate the biochemical composition of the extracts to their anti-angiogenic activity arabic 19 English 119

The extra demand imposed upon the Libyan health services during and after the Libyan revolution in 2011 led the ailing health systems to collapse. To start the planning process to re-engineer the health sector, the Libyan Ministry of Health in collaboration with the World Health Organisation (WHO) and other international experts in the field sponsored the National Health Systems Conference in Tripoli, Libya, between the 26th and the 30th of August 2012. The aim of this conference was to study how health systems function at the international arena and to facilitate a consultative process between 500 Libyan health experts in order to identify the problems within the Libyan health system and propose potential solutions. The scientific programme adopted the WHO health care system framework and used its six system building blocks: i) Health Governance; ii) Health Care Finance; iii) Health Service Delivery; iv) Human Resources for Health; v) Pharmaceuticals and Health Technology; and vi) Health Information System. The experts used a structured approach starting with clarifying the concepts, evaluating the current status of that health system block in Libya, thereby identifying the strengths, weaknesses, and major deficiencies. This article summarises the 500 health expert recommendations that seized the opportunity to map a modern health systems to take the Libyan health sector into the 21st century arabic 10 English 65

Aim: The aim of the study was to assess the success and possible complications of closed reduction (CR) treatment of developmental hip dysplasia (DHD) in late‑diagnosed children and explores its relation to the acetabular index (AI) measurement prior to treatment. Patients and Methods: Twenty‑three consecutive patients with dislocated hips, 16 unilateral and 7 bilateral (30 hips), were retrospectively included in the study. They were admitted to the specialist pediatric orthopedic unit of the University Hospital (Tripoli Medical Center) in Tripoli, Libya. There were 21 females and 2 males with an average age at diagnosis of 17 months (range from 14 to 31 months). Their average follow‑up period was 3 years (2–5 years), and none of them received treatment prior to diagnosis. All patients received prior inpatient skin traction for at least 2 weeks followed by CR with soft tissue release (adductor tenotomy), hip spica applied and maintained for an average of 3 months. Patients who had a failure of reduction or resubluxation at follow‑up went for open reduction and a reconstruction procedure. Results: CR was successful in 27 hips (90%), failed in 3 (10%) other, the average age of the successful reduction group was 20.5 months, while that of the open reduction group, it was 23 months (Р = 0.25). The average AI of the CR group was 39.0°, while that of the open reduction group, it was 42.7° (Р = 0.15); 6.7% of patients with an AI of 40° had a failure of CR of the hip (Р = 0.46). No complications of treatment were recorded at follow‑up. Conclusion: Staged CR of DHD in older children in the hands of experienced specialists is still a valid means of their treatment, especially in developing countries with limited resources. There is a relatively higher failure rate of CR, the older the child is and the higher the AI. arabic 11 English 78
