Objectives: The objective of this study is to study the demographic, clinicopathological features, and geographical distribution of differentiated thyroid cancer (DTC) among Libyan patients referred from all parts of the country to the nuclear medicine department, for radioactive iodine (RAI) therapy.Materials and Methods: Retrospective review of medical records of 265 patients with differentiated thyroid carcinoma (DTC) referred to RAI therapy in the Nuclear Medicine Branch‑Tripoli Medical Center, in the period from May 2005 to October 2010. The data analyzed included sex, age at the time of diagnosis, the city of residence, pathological diagnosis, the extent of disease, and types of treatment.Results: There were 225 (84.9%) females and 40 (15.1%) males giving a sex ratio of 5.6:1. The mean age of males at diagnosis was 51.2 ± 14.8 (range 24–78) years and  the  mean age  of  the  females was  44.6 ± 15.6 (range 10–95) years. Two  hundred and  twenty‑three (84.2%) had  papillary thyroid cancer (PTC), 31 (11.7%) had  follicular thyroid cancer, 3 (1.1%) had  Hurthle cell  thyroid cancer, and  2 (0.8%) had follicular‑insular thyroid cancer. About 43 (16.2%) had  a  history of  multinodular goiter, and  3 (1.1%) Hashimoto’s thyroiditis. From data  collected, cervical lymph node metastases were found in 45 (17.0%), and distal metastases in 27 (10.2%).Conclusions: PTC was the most common type of DTC. DTC was more common among females. The current study showed that the disease tends to occur at an older age, and with less cervical lymph node metastases than previously reported.

Abstract The incidence of spinal cord injuries is the lowest of all major trauma, with devastating impact on the individual affected. The immediate treatment, though it remains mainly supportive, in many situations will determine the outcome and the cost of health care. Standards of care are unfortunately still lacking, this is mainly due to the existing controversies and lack of effective treatment of the injured cord. The author discusses here some of the controversial points based on literature review and personal observation. arabic 14 English 75

Background: Thiopurine S-methyltransferase (TPMT) is a cytosolic enzyme that catalyses the S-methylation of 6-mercaptopurine and azathioprine. Low activity phenotypes are correlated with polymorphism in the TPMT gene. Patients with low or undetectable TMPT activity could develop severe myelosuppression when they are treated with standard doses of thiopurine drugs. Since ethnic differences in the TPMT gene polymorphism have been demonstrated worldwide, assessing it in the Libyan population is worthwhile. Methods: We investigated TPMT gene polymorphism in a total of 246 Libyan healthy adult blood donors from three different Libyan regions (Tripoli, Yefren, and Tawargha) and 50 children with acute lymphoblastic leukaemia (ALL). We used polymerase chain reaction restriction length polymorphism (PCR-RFLP) and allele-specific PCR-based assays to analyse the TPMT gene for the variants* 2 c. 238 G> C,* 3A (c. 460 G> A and c. 719 A> G),* 3B (c. 460 G> A), and* 3C (c. 719 A> G). Results: Our results show that the TPMT variants associated with low enzymatic activity were detected in 3.25%(8 in 246) of adult Libyan individuals and the frequency of total mutant alleles was 1.63%. Heterozygous genotypes were TPMT* 3A in three subjects (0.61%) and TPMT* 3C in five subjects (1.02%). No TPMT* 2 and TPMT* 3B allelic variants and no homozygous or compound heterozygous mutant alleles were detected. The normal allele (wild-type) was found in 98.4% of the adult individuals studied. No mutant alleles were detected among the 50 children who had ALL. arabic 10 English 74
