The aim of this study was to identify nationals at risk of developing type 2 diabetes within the next 10 years in some areas across Tripoli Health Authority in Libya. In this questionnaire‐based survey, a total of 400 Libyan nationals of both genders were randomly selected from seven areas across the central area of Tripoli Health Authority (Soug El‐Juma, Zawet Dahmani, Al‐Furnaj, Ain Zara, Al‐Madena Centre, Al‐Dhahra Centre, and Noflean). All participants approached (400) completed the study and responded to the items of the survey. Based on a modified Finnish Type 2 Diabetes Risk Score test (FINDRISC), 129 (32.3%) were categorised as either at moderate or at high/very high risk of developing diabetes within the next 10 years of life. Among the 129 participants at risk, body mass index was >25 kg/m2 in 125 (96.9%) and waist circumferences were high (>88 cm for females;>102 cm for males) in almost 45% of the women and 22% of the men. We found that in the sample studied the risk of developing diabetes was clear, and there is no doubt that interventions to reduce such risk are a priority rather than a need. Diabetes has a great impact on the health of the nation and also on the future resources of the country in managing the disease and its complications; a health education/health campaign could be one good answer to tackle the problem. arabic 9 English 54

Exposures to a wide variety of environmental substances are negatively associated with many biological cell systems both in humans and rodents. Trichloroethane (TCE), a ubiquitous environmental toxicant, is used in large quantities as a dissolvent, metal degreaser, chemical intermediate, and component of consumer products. This increases the likelihood of human exposure to these compounds through dermal, inhalation and oral routes. The present in vivo study was aimed to investigate the possible cellular and molecular etiology of liver abnormality induced by early exposure to TCE using a murine model. The results showed a significant increase in liver weight. Histopathological examination revealed a TCE-induced hepatotoxicity which appeared as heavily congested central vein and blood sinusoids as well as leukocytic infiltration. Mitotic figures and apoptotic changes such as chromatin condensation and nuclear fragments were also identified. Cell death analysis demonstrates hepatocellular apoptosis was evident in the treated mice compared to control. TCE was also found to induce oxidative stress as indicated by an increase in the levels of lipid peroxidation, an oxidative stress marker. There was also a significant decrease in the DNA content of the hepatocytes of the treated groups compared to control. Agarose gel electrophoresis also provided further biochemical evidence of apoptosis by showing internucleosomal DNA fragmentation in the liver cells, indicating oxidative stress as the cause of DNA damage. These results suggest the need for a complete risk assessment of any new chemical prior to its arrival into the consumer market.

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.
